OData

Advanced

OData (Open Data Protocol) is an ISO/IEC-approved OASIS standard. It defines a set of best practices for building and using REST API. Use OData to create REST-based services that let you publish and edit resources using simple HTTP requests. Such resources should be identified with a URL and defined in the data model. Creatio supports OData 4 and OData 3 protocols. OData 4 provides more features than OData 3. The main difference between the protocols is the data format of the server's response. Learn more about the differences between OData 3 and OData 4 protocols in the official OData documentation. Use OData 4 for Creatio integration.

All external requests to the Creatio application must be authenticated. We recommend using cookie-based authentication (form-based authentication) implemented with AuthService.svc web service for OData requests.

OData 4 protocol

The odata web service provides access to Creatio objects via the OData 4 protocol.

The OData service URL for .NET Framework

https://mycreatio.com/0/odata

The OData service URL for .NET Core

https://mycreatio.com/odata

OData 3 protocol

The EntityDataService.svc web service provides access to Creatio objects via the OData 3 protocol.

The EntityDataService.svc server address

https://mycreatio.com/0/ServiceModel/EntityDataService.svc

Use the EntityDataService.svc service to work with Creatio objects in a WCF client.

Windows Communication Foundation (WCF) is a program framework that handles data exchange between applications. WCF is a part of .NET Framework.

The WCF client operates via receiving the service metadata and creating client proxy classes. The client application will communicate with Creatio's EntityDataService.svc service using these mediator classes.

To implement the client application:

1. Create a .NET project where you will implement the Creatio integration.

2. Generate client proxy classes for the EntityDataService.svc service.

3. Create a context instance of the EntityDataService.svc service's runtime environment.

4. Implement the integration's client business logic using the methods of the proxy class instance.

There are several ways to generate the proxy classes for the EntityDataService.svc service:

Using the DataServiceModel Metadata Utility Tool (DataSvcutil.exe) .

From the Visual Studio client application project.

Generate proxy classes using the DataServiceModel Metadata Utility Tool

DataSvcUtil.exe is a command line program provided by WCF Data Services . The utility uses the OData channel and generates the data service's client classes required to access the service from the .NET Framework client application. The data classes are generated using the following metadata sources:

WSDL – the service metadata document. Describes the data model provided by the data service.

CSDL – the data model file. Uses the common schema definition language ( CSDL ). Learn more: [MC–CSDL]: Conceptual Schema Definition File Format.

EDMX – an *.xml file. Create it using programs for working with the EDM model. The programs are included in the Entity Framework . Learn more: [MC–EDMX]: Entity Data Model for Data Services Packaging Format.

The DataSvcUtil.exe tool is usually installed in the C:\Windows\Microsoft.NET\Framework\v4.0 directory. For 64-bit systems, the respective directory is usually C:\Windows\Microsoft.NET\Framework64\v4.0 .

The DataSvcutil.exe utility calling format

datasvcutil /out:file [/in:file | /uri:serviceuri] [/dataservicecollection] [/language:devlang] [/nologo] [/version:ver] [/help]

Find the detailed information about the DataSvcutil.exe utility in the official MSDN documentation.

Generate proxy classes from the Visual Studio client application project To generate proxy classes from the Visual Studio client application project:

1. Right-click the project where you want to implement Creatio integration and select [ Add Service Reference… ] in the context menu.

2. Enter the complete address of the EntityDataService.svc service in the [ Address ] field.

3. Click [ Go ] and specify the Creatio user credentials. The entities supported by the service will appear in the

[ Services ] window upon success. 4. Specify the namespace to include the generated proxy classes in the [ Namespace ] field. For example, CreatioServiceReference . You will also need to link this namespace in the using block of the project.

5. Click [ OK ] to generate the proxy classes. This will add a new Reference.cs code file with the description of proxy classes to the project. Use the classes to call and interact with the data service's resources as objects.

Visual Studio also lets you generate the service's proxy classes from the service metadata file stored on your drive. To do this, enter the complete path to the metadata file, starting from the file:// prefix, in the [ Address ] field.

file://C:/metadata.xml

Visual Studio will link the Microsoft.Data.Services.Client.dll build in the project upon generating the service's proxy classes. This ensures OData 3 protocol support. If the client application requires an earlier version of the protocol, link the corresponding build manually. This client library lets you call the EntityDataService.svc data service using the standard .NET Framework programming templates and the LINQ request language.

Add the using directives to and declare the variable of the OData service address in the project code to ensure successful compilation.

The Using directives

using System; using System.Data.Services.Client; using System.Net; using Terrasoft.Sdk.Examples.CreatioServiceReference; using System.Linq;

Declare the variable of the OData service address

private static Uri serverUri = new Uri("http:////0/ServiceModel/EntityDataService.svc/");

The limitations of OData protocol When using the OData protocol, keep in mind the following limitations:

It is not possible to create system users. It is not possible to specify the culture of the returned data. The culture is determined by the culture of the user on whose behalf you executed the request.

The response body can contain up to 20 000 lines. A batch request can contain up to 100 sub-requests.

OData integration examples

Advanced

View the Creatio API documentation with examples of various CRUD operations to the Creatio via OData 3 and OData 4 protocols on a separate web resource. Stream data type request examples

Advanced

The following elements have the Stream data type:

Images Files

Binaries

Use the following standard methods to work with the Stream data type:

GET – retrieve data

POST – add data

Batch request examples

Advanced

Batch requests combine multiple HTTP requests by specifying each request as a separate object in the batch request's body. The Creatio database server returns a single HTTP response that contains the responses to each request. Use batch requests to improve Creatio performance. The batch requests utilize:

The POST HTTP method.

The $batch parameter.

The Content-Type header.

The values of the Content-Type header:

application/json – restricts the content the server returns for each request within the batch request to a single type.

multipart/mixed – allows you to set unique Content-Type headers for each request in the batch request body.

If one of the requests completes with a 4xx-5xx group response code, the subsequent requests will not be executed. Add the Prefer: continue-on-error header to the main HTTP request to enable the execution of the subsequent requests.

Attention. A batch request can contain up to 100 requests.

WCF client request examples

Advanced

Use the DataServiceQuery universal class to retrieve the service's object collection. This class is a request to the service that retrieves the collection of a specific type of entities.

Create a context object instance of the Creatio application environment to execute a request to EntityDataService.svc .

The examples in this article will use the forms authentication.

To implement the forms authentication:

1. Create a LoginClass class.

2. Implement the authServiceUri (a string that requests the Login method of the AuthService.svc authentication service) and AuthCookie (Creatio's authentication cookies) fields.

3. Implement the TryLogin(string userName, string userPassword) method that authenticates the user and saves the server's response to the AuthCookie field.

4. Implement the OnSendingRequestCookie(object sender, SendingRequestEventArgs e) method that will be called in response to an event of the SendingRequest context instance (creating a new HttpWebRequest instance).

The OnSendingRequestCookie method authenticates the user and adds the cookies received in response to the data request.

OnSendingRequestCookie

static void OnSendingRequestCookie(object sender, SendingRequestEventArgs e) { // Call the method of the LoginClass class that authenticates the user's method passed in the parameters. LoginClass.TryLogin("CreatioUserName", "CreatioUserPassword"); var req = e.Request as HttpWebRequest;

// Add the received authentication cookies to the data request. req.CookieContainer = LoginClass.AuthCookie; e.Request = req; }

There are several ways to execute the service request:

A LINQ request to the named DataServiceQuery object received from the service context.

Implicit enumeration of the DataServiceQuery object received from the service context.

Explicit call of the Execute method of the DataServiceQuery object. Call the BeginExecute method for asynchronous execution.

Retrieve a contact collection via a LINQ request.

Example. Define and implement the LINQ request that returns all contact entities of the EntityDataService.svc service.

Implement the example

The LINQ request

public static void GetOdataCollectioByLinqWcfExample() { // Create the Creatio application context. var context = new Creatio(serverUri); // Define the method that adds authentication cookies upon creating a new request. context.SendingRequest += new EventHandler(OnSendingRequestCookie); try { // Build a LINQ request to retrieve the contact collection. var allContacts = from contacts in context.ContactCollection select contacts; foreach (Contact contact in allContacts) { // Execute the contact actions. } } catch (Exception ex) { // Process errors. } }

Retrieve a contact collection via an implicit request

Example. Use context to execute an implicit request that retrieves all contact entities of the EntityDataService.svc service.

Implement the example

GetOdataCollectionByImplicitRequestExample()

public static void GetOdataCollectionByImplicitRequestExample() { // Create the Creatio application context. var context = new Creatio(serverUri); // Define the method that adds authentication cookies upon creating a new request. context.SendingRequest += new EventHandler(OnSendingRequestCookie); try { // Define an implicit request that retrieves the contact collection from the service. DataServiceQuery allContacts = context.ContactCollection; foreach (Contact contact in allContacts) { // Execute the actions with contacts. } } catch (Exception ex) { // Process errors. } }

Retrieve a contact collection via an explicit request

Example. Use the DataServiceContext context to execute an explicit request that retrieves all contact entities of the EntityDataService.svc service.

Implement the example

GetOdataCollectionByExplicitRequestExample()

public static void GetOdataCollectionByExplicitRequestExample()

{ // Define the Uri of the service request that returns the contact collection. Uri contactUri = new Uri(serverUri, "ContactCollection"); // Create the Creatio application context var context = new Creatio(serverUri); // Define the method that adds authentication cookies upon creating a new request. context.SendingRequest += new EventHandler(OnSendingRequestCookie); try { // Call the Execute<>() method to execute an explicit request to the service. foreach (Contact contact in context.Execute(contactUri)) { // Execute the contact actions. } } catch (Exception ex) { // Process errors. } }

CRUD operation examples

Retrieve an object

public static void GetOdataObjectByWcfExample() { // Create the Creatio application context. var context = new Creatio(serverUri); // Define the method that adds authentication cookies upon creating a new request. context.SendingRequest += new EventHandler(OnSendingRequestCookie); // var contact = context.ContactCollection.Where(c => c.Name.Contains("User")).First(); // Execute the contact actions. }

Create an object

public static void CreateCreatioEntityByOdataWcfExample() { // Create a new contact and initialize its properties. var contact = new Contact() { Id = Guid.NewGuid(),

Name = "New Test User" }; // Create a new account to which the contact is connected and initialize the account's properties. var account = new Account() { Id = Guid.NewGuid(), Name = "Some Company" }; contact.Account = account; // Create the Creatio application context. var context = new Creatio(serverUri); // Define the method that adds authentication cookies upon creating a new request. context.SendingRequest += new EventHandlerl(OnSendingRequestCookie); // Add the contact to the service data model's contact collection. context.AddToAccountCollection(account); // Add the account to the service data model's account collection. context.AddToContactCollection(contact); // Connect the contact to the account in the service data model. context.SetLink(contact, "Account", account); // Save the changes to Creatio in a single request. DataServiceResponse responces = context.SaveChanges(SaveChangesOptions.Batch); // Process the server's responses. }

Update an object

public static void UpdateCreatioEntityByOdatetWcfExample() { // Create the Creatio application context. var context = new Creatio(serverUri); // Define the method that adds authentication cookies upon creating a new request. context.SendingRequest += new EventHandler(OnSendingRequestCookie); // Select a collection's contact to update. var updateContact = context.ContactCollection.Where(c =< c.Name.Contains("Test")).First(); // Update the contact's properties. updateContact.Notes = "New updated description for this contact."; updateContact.Phone = "123456789"; // Save the changes to the service data model. context.UpdateObject(updateContact); // Save the changes to Creatio in a single request. var responces = context.SaveChanges(SaveChangesOptions.Batch); }

Delete an object

public static void DeleteCreatioEntityByOdataWcfExample() { // Create the Creatio application context. var context = new Creatio(serverUri);

context.SendingRequest += new EventHandler(OnSendingRequestCookie); // Select a contact collection's object to delete. var deleteContact = context.ContactCollection.Where(c => c.Name.Contains("Test")).First(); // Delete the object from the service data model. context.DeleteObject(deleteContact); // Save the changes to Creatio in a single request. var responces = context.SaveChanges(SaveChangesOptions.Batch); // Process the server's responses. }

Available status codes

200 OK A request that does not create a resource was completed successfully, and the resource's value does not equal 0. In this case, the response body should contain the value of the resource specified in the request URL. The information in the response depends on the request method: GET – the resource was found and passed in the response body.

POST – the resource with the description of server actions caused by the request was passed in the response body.

201 Created A request that creates a resource successfully. The response body should contain the created resource. Used for POST requests that create a collection, create a multimedia object (e. g., a photo), or call an action through import.

202 Accepted Data request processing has started but has not finished yet. There is no guarantee that the request will be completed successfully (asynchronous request processing).

204 No content The request was processed successfully, but there is no need to return any data. The value of the requested resource is 0. The response will pass only the headers, the response body should be empty.

3xx Redirection Redirection means the client must take further actions to execute the request. The response should contain the Location header with the URL that can be used to retrieve the result. The response can also contain the Retry-After header that displays time, in seconds. The time specifies how long the client can wait before executing another request to the resource in the Location header.

304 Not modified The client executes a GET request with the If-None-Match header, and the content remains unchanged. The response should not contain any other headers.

403 Forbidden The request is correct, but the server refused to authorize it. This means the client lacks permissions to work with the resource. This may be caused by an invalid BPMCSRF cookie.

404 Not Found The server cannot find the resource specified in the URL. The response body may contain additional information.

405 Method Not Allowed The resource specified in the request URL does not support the specified request method. The response should contain the Allow header with the list of request methods the resource supports.

406 Not Acceptable The resource specified in the request URL does not have any current view that is acceptable for the client as per Accept , Accept-Charset , and Accept-Language request headers. The service does not provide a default view.

410 Gone The requested resource is no longer available. The resource had used the specified URL but was deleted and is no longer available.

412 Prediction Failed The client specified a request header condition the resource cannot process.

424 Failed Dependency The current request cannot be processed because the requested action depends on another action that could not be executed. The request has not been executed due to dependency failure.

501 Not Implemented The client is using a request method that is not implemented in OData 4 protocol and cannot be processed. The response body should contain the description of the unimplemented functionality.

Response body

@odata.context

Information about the type of the returned data. Besides the data source path, the data_resource element can contain the $entity parameter. This parameter indicates that the response returned a single instance of the collection object. Available only for GET and POST requests.

Advanced

The Creatio DataService web service is a RESTfull service. RESTful is a quite simple information management interface that doesn't use any additional internal layers, i.e., the data doesn't need to be converted to any third- party format, such as XML. In a simple RESTful service, each record is uniquely identified by a global identifier such as URL. Each URL, in turn, has a strictly specified format. However, this service is not always convenient for transferring large amounts of data. With the use of the DataService, the data can be automatically configured in various data formats such as XML, JSON, HTML, CSV, and JSV. The data structure is determined by data contracts. The full list and description of the DataService data contracts is displayed on table.

The Creatio application DataService services

Service Description

InsertQuery Add section record query class.

UpdateQuery Update section record query class.

DeleteQuery Delete section record query class.

SelectQuery Select section record query class.

BatchQuery Package query class.

Filters Filter class.

Resctrictions when using DataService When using DataService, take into account the following restrictions:

1. Maximum number of records that you can obtain by request is specified in the [ MaxEntityRowCount ] (the default value is 20000). You can change the system setting value in the .\Terrasoft.WebApp\Web.config file.

Attention. We do not recommend changing the [ MaxEntityRowCount ] system setting. This may lead to performance issues. We recommend using the page-oriented display implemented in the " IsPageable " and " RowCount " properties of the SelectQuery data contract.

2. The number of requests is unlimited.

Add a button to create a new record in the [Contacts] section

Advanced

Example. Add to the [ Contacts ] section a button that when clicked invokes a method, using the InsertQuery class that adds a record with the following data:

Full name — John Best;

Full job title — Developer;

Business phone — +12 345 678 00 00.

Example implementation algorithm

1. Add button to the [ Contacts ] section For this particular case, you need to create a replacement client module of the [ Contacts ] section.

In the created client schema, add the InsertQueryContactButtonCaption localizable string, and set the "Add contact" value to it.

Add a configuration object with the button location settings to the diff array.

diff

diff: /**SCHEMA_DIFF*/[ // Metadata to be added to the custom button section. { // The element is added to the page. "operation": "insert", // Parent interface element name to which the button is added. "parentName": "ActionButtonsContainer", // The button is added to the interface element collection // of the parent element (its metaname is specified in parentName). "propertyName": "items", // Added button metaname. "name": "InsertQueryContactButton", // Additional element properties. "values": { // Added element type — button. itemType: Terrasoft.ViewItemType.BUTTON, // Binding button caption to the localizable schema string. caption: { bindTo: "Resources.Strings.InsertQueryContactButtonCaption" }, // Binding method of processing the button click. click: { bindTo: "onInsertQueryContactClick" }, "layout": { "column": 1, "row": 6, "colSpan": 1 } } } ]/**SCHEMA_DIFF*/

2. Add the processing method for the button click event In order for a record with the necessary data to be added when a button created in the section is clicked, add the following method to the methods section of the replacement client schema:

methods

methods: { // Method of processing the button click. onInsertQueryContactClick: function() { // Creating the Terrasoft.InsertQuery class instance. var insert = Ext.create("Terrasoft.InsertQuery", { // Root schema name. rootSchemaName: "Contact" });

// Setting the Terrasoft.ParameterExpression value-parameters. // A value-parameter instance is created and added to the column value collection. // Creating a value-parameter instance for the [Job title] column. insert.setParameterValue("Name", "John Best", Terrasoft.DataValueType.TEXT); // Creating a value-parameter instance for the [Business phone] column. insert.setParameterValue("Phone", "+12 345 678 00 00", Terrasoft.DataValueType.TEXT); // Creating a value-parameter instance for the [Job title] column. insert.setParameterValue("Job", "11D68189-CED6-DF11-9B2A-001D60E938C6", Terrasoft.DataValueType.GUID); // Data update query. insert.execute(function(response) { // Displaying server answer window.console.log(response); }); // Updating list data. this.reloadGridData(); } }

Attention. Unlike the previous example, authorization is not required because the code is executed directly in the Creatio application.

The implementation of the InsertQuery class for the client part of the application kernel is different from the implementation of the InsertQuery in its back end. So, to create the parameters, the setParameterValue method is used, and for the query execution — the execute method. Learn about all the available properties and methods of the InsertQuery class implemented in the kernel client part in the API documentation. Add a button to read records in the [Contacts] section

Advanced

Example. In the [ Contacts ] section, add a button which will open the method that will use DataService to read records in the [ Contacts ] section with the following columns:

Id ;

Full name ;

Number of activities — aggregate column, which displays the number of activities of this contact.

Example implementation algorithm

1. Add a button in the [ Contacts ] section Create a replacing client module of the [ Contacts ] section.

In the created client schema, add SelectQueryContactButtonCaption localizable string and set its value to Select contacts.

Add a configuration object with the settings determining the button position to the diff array.

diff

//Setup of section button display. diff: /**SCHEMA_DIFF*/[ // Metadata for adding a custom button in a section. { // Indicates that an elementis added on a page. "operation": "insert", // Meta name of the parent control element where the button is added. "parentName": "ActionButtonsContainer", // Indicates that the button is added to the control element collection // of parent element (meta-name specified in parentName). "propertyName": "items", // Meta-name of the added button. "name": "SelectQueryContactButton", // Additional properties of the element. "values": { // Type of added element - button. itemType: Terrasoft.ViewItemType.BUTTON, // Binding button title to a schema localizable string.

caption: { bindTo: "Resources.Strings.SelectQueryContactButtonCaption" }, // Binding of the button pressing handler method. click: { bindTo: "onSelectQueryContactClick" }, "layout": { "column": 1, "row": 6, "colSpan": 1 } } }

]/**SCHEMA_DIFF*/

2. Add handler method for the button pressing event

To enable reading the records when the button is clicked, add the following method to the methods section of the replacing client schema:

methods

methods: { // Handler method for button click. onSelectQueryContactClick: function() { // Creating an instance of the Terrasoft.InsertQuery class. var select = Ext.create("Terrasoft.EntitySchemaQuery", { // Root schema name. rootSchemaName: "Contact" }); // Adding the [Full name] column to query. select.addColumn("Name"); // Adding [Number of activities] aggregate column to a query. select.addAggregationSchemaColumn( // Path to column in relation to the root schema. "[Activity:Contact].Id", // Aggregation type — quantity. Terrasoft.AggregationType.COUNT, // Column title. "ActivitiesCount", // Aggregation function scope - for all elements. Terrasoft.AggregationEvalType.ALL); // Update query to server // Getting whole collection of records and displaying it in the browser console. select.getEntityCollection(function(result) { if (!result.success) { // Processing/logging of error. this.showInformationDialog("Data query error");

return; } // Displayed message. var message = ""; // Analyzing resulting collection and generating displayed message. result.collection.each(function(item) { message += "Full name: " + item.get("Name") + ". Number of activities: " + item.get("ActivitiesCount") + "\n"; }); // Displaying message in console. window.console.log(message); }, this); } }

Note. Unlike the previous example, authentication is not needed in this case, because the program code is executed by Creatio directly.

In the client of the application core, there is not a class like the server core SelectQuery class. To select data from a section, use the Terrasoft.EntitySchemaQuery class. For more information on this class methods and properties are described in the API documentation. Filter records in the [Contacts] section

Advanced

Example. Create a console application that will read the following data from the [ Contacts ] section using the DataService service:

Id ;

Full name ;

Number of activities is an aggregating column that shows the number of activities of this contact.

It is necessary to filter the data so that only those contacts whose number of activities is in the range of 1 to 3, and the [ Full name ] column value starting with "H" are read.

Example implementation algorithm

1. Сreate and configure a C# console application project that reads records To perform this step, you must perform the example of reading records in a third-party application.

The result of the query class implementation instance to read the records with the columns in an abbreviated form:

SelectQuery()

// Query class instance. var selectQuery = new SelectQuery () { // Root schema name. RootSchemaName = "Contact", // Adding columns to query. Columns = new SelectQueryColumns () { // Column collection. Items = new Dictionary () { // Column [Full name]. { // Key. "Name", // Value. new SelectQueryColumn () { // An expression that specifies the column type. Expression = new ColumnExpression () { // Expression type - schema column. ExpressionType = EntitySchemaQueryExpressionType.SchemaColumn, // Path to the column. ColumnPath = "Name" } } } // Column [Number of activities]. { "ActivitiesCount", new SelectQueryColumn () { Expression = new ColumnExpression () { // Expression - subquery. ExpressionType = EntitySchemaQueryExpressionType.SubQuery, // Path to the column relative to the root schema. ColumnPath = "[Activity: Contact] .Id", // Function type - aggregating. FunctionType = FunctionType.Aggregation, // Aggregation type - number. AggregationType = AggregationType.Count

} } } } } };

2. Add filter implementation

In order to filter data, you must create an instance of the Filters collection class instance, fill in the necessary properties, and then pass the link to this instance to the Filters property of the query class instance that you created in the previous step.

Filter collection class implementation example

// Query filters. var selectFilters = new Filters () { // Filter Type - group. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.FilterGroup, // Filter collection. Items = new Dictionary { // Filter Implementation. } }; // Adding filter to query. selectQuery.Filters = selectFilters; // Query class instance serialization to read data from the JSON string. var json = new JavaScriptSerializer () Serialize (selectQuery).;

The Items property must contain the key-value type collection. The key is a string containing the filter name, and the value is an instance of the Filter class that contains a direct implementation of the filter.

To implement a filter that selects only those contacts that have a number of activities within a range of 1 to 3, you must add the following instance to the collection of filters:

Example of the instance to the collection of filters

// Filtration by activity. { // Key. "FilterActivities", // Value. new Filter {

// Filter type - range filter. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.Between, // Comparison type - range. ComparisonType = FilterComparisonType.Between, // An expression to be tested. LeftExpression = new BaseExpression () { // Expression type - subquery. ExpressionType = EntitySchemaQueryExpressionType.SubQuery, // Path to the column relative to the root schema. ColumnPath = "[Activity: Contact] .Id", // Function type - aggregating. FunctionType = FunctionType.Aggregation, // Aggregation type - number. AggregationType = AggregationType.Count } // Filter range final expression. RightGreaterExpression = new BaseExpression () { // Expression type - parameter. ExpressionType = EntitySchemaQueryExpressionType.Parameter, // Expression parameter. Parameter = new Parameter () { // Parameter data type - integer. DataValueType = DataValueType.Integer, // Parameter value. Value = 3 } } // Filter range initial expression. RightLessExpression = new BaseExpression () { ExpressionType = EntitySchemaQueryExpressionType.Parameter, Parameter = new Parameter () { DataValueType = DataValueType.Integer, Value = 1 } } } }

Add the following instance to the filter collection to filter contact records where the [ Full name ] column value begins with "H":

Example of the instance to the filter collection

// Filtering by name. { // Key. "FilterName", // Value. new Filter { // Filter type - comparison filter. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.CompareFilter, // Comparison type - starts with an expression. ComparisonType = FilterComparisonType.StartWith, // Expression to be tested. LeftExpression = new BaseExpression () { // Expression type - schema column. ExpressionType = EntitySchemaQueryExpressionType.SchemaColumn, // Path to the column. ColumnPath = "Name" } // Filtration expression. RightExpression = new BaseExpression () { // Expression type - parameter. ExpressionType = EntitySchemaQueryExpressionType.Parameter, // Expression parameter. Parameter = new Parameter () { // Parameter data type - text. DataValueType = DataValueType.Text, // Parameter value. Value = "CH" } } } }

Filter records in the [Contacts] section using a macro

Advanced

Example. Create a console application that uses DataService to read records from the [ Contacts ] section with the following columns:

Id ;

Full name ;

Birth date .

The data must be filtered, so that only contacts who were born in 1992 are shown.

Example implementation algorithm

1. Create and set up a C# application project that reads records To execute this step, execute the record reading example. The result of implementing an instance of query class for reading records:

SelectQuery()

// Instance of query class. var selectQuery = new SelectQuery() { // Root schema name. RootSchemaName = "Contact", // Adding columns to query. Columns = new SelectQueryColumns() { // Collection of columns. Items = new Dictionary() { //Column [Full name]. { // Key. "Name", // Value. new SelectQueryColumn() { // Expression that specifies the column type. Expression = new ColumnExpression() { // Type of expression - schema column. ExpressionType = EntitySchemaQueryExpressionType.SchemaColumn, // Pat to column. ColumnPath = "Name" } } }, // Column [Number of activities]. { "ActivitiesCount",

new SelectQueryColumn() { Expression = new ColumnExpression() { // Expression type — subquery. ExpressionType = EntitySchemaQueryExpressionType.SubQuery, // Path to column relative to the oot schema. ColumnPath = "[Activity:Contact].Id", // Function tyoe — aggregation. FunctionType = FunctionType.Aggregation, // Aggregation type — quantity. AggregationType = AggregationType.Count } } } } } };

2. Add a filter implementation with macros

To filter the data, create an instance of the Filters collection class, fill out the properties with corresponding values, and then pass the instance link to the Filters property of the query class created on the previous step.

An example of filter collection class implementation

// Query filters. var selectFilters = new Filters() { // Filter type — group. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.FilterGroup, // Filter collection. Items = new Dictionary {

// Filter by year of birth. { // Key. "FilterYear", // Value. new Filter { // Filter type — comparison. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.CompareFilter, // Comparison type — equal. ComparisonType = FilterComparisonType.Equal, // Expression to check.

LeftExpression = new BaseExpression() { // Expression type — schema column. ExpressionType = EntitySchemaQueryExpressionType.SchemaColumn, // Path to schema. ColumnPath = "BirthDate" }, // Expression with which the checked value is compared. RightExpression = new BaseExpression { // Expression type — function. ExpressionType = EntitySchemaQueryExpressionType.Function, // Function type — macro. FunctionType = FunctionType.Macros, // Macro type — year. MacrosType = EntitySchemaQueryMacrosType.Year, // Function argument. FunctionArgument = new BaseExpression { // Type of expression that determines the argument — parameter. ExpressionType = EntitySchemaQueryExpressionType.Parameter, // Parameter initialization. Parameter = new Parameter { // Parameter type — integer. DataValueType = DataValueType.Integer, // Parameter value. Value = "1992" } } } } } } }; // Adding filters to query. selectQuery.Filters = selectFilters; // Serialization of select query class instance in a JSON string. var json = new JavaScriptSerializer().Serialize(selectQuery);

The collection contains a single filter with the FilterYear key. Because only those records that have their year of birth equal to 1992 must be selected from the collection, the type of filter is set as a comparison filter. The type of comparison is set as an equality of values. As a verified expression, set the [ Date of birth ] column. Specify the macro function as the expression to compare with.

In this case using a macro is optimal because the birth date is stored in the database in YYYY-MM-DD format. The macro automatically determines the year value, so the developer does not need to write additional program code.

Because the EntitySchemaQueryMacrosType.Year macro is parametric, the FunctionArgument property must be

initialized and assigned a link to an instance of the BaseExpression class. In it, the integer parameter with value "1992" is defined. Update a record in the [Contacts] section

Advanced

Example. Create a console application that used DataService to update the "John Smith" record added in the example. Add "[email protected]" as the value in the [ Email ] column of this record.

Example implementation algorithm

1. Create and set up a C# application project Using the Microsoft Visual Studio development environment (version 2017 and up), create a Visual C# console application project and specify project name, for example, DataServiceUpdateExample . Set ".NET Framework 4.7" for the project property Target framework .

In the References section of the project, add dependencies from the following libraries:

System.Web.Extensions.dll – class library included in .NET Farmework;

Terrasoft.Core.dll – library of base Creatio server core classes. It can be found using the following path: [Creatio setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Core.dll ;

Terrasoft.Nui.ServiceModel.dll — application service class library. It can be found using the following path: [Creatio setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Nui.ServiceModel.dll ;

Terrasoft.Common.dll – library of base Creatio server core classes. It can be found using the following path: [Creatio setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Common.dll .

Add the using directives to the application source code file:

Adding the using directives

using System; using System.Text; using System.IO; using System.Net; using System.Collections.Generic; using Terrasoft.Nui.ServiceModel.DataContract; using Terrasoft.Core.Entities; using System.Web.Script.Serialization; using Terrasoft.Common;

2. Add fields and constants and field declarations to the source code To access DataService features, add the fields and constants to the application source code.

Adding the fields and constants

// Primary URL of Creatio application. Must be repoaced with a custom one. private const string baseUri = @"http://example.creatio.com"; // Request string to the Login methid of the AuthService.svc service. private const string authServiceUri = baseUri + @"/ServiceModel/AuthService.svc/Login"; // Path string for the UpdateQuery. private const string updateQueryUri = baseUri + @"/0/DataService/json/reply/UpdateQuery"; // Creatio authentication cookie. private static CookieContainer AuthCookie = new CookieContainer();

Here, three string fields are declared. These fields will be used to form authentication query and read data queries execution paths. Authentication data will be saved in the AuthCookie field.

3. Add method that performs Creatio application authentication аAuthentication is required to enable access to the DataService for the created application.

4. Add implementation of the record add query

Because the updateQueryUri constant declared earlier contains a path for sending data in the JSON format, sent data must be configured beforehand as a string that contains a JSON object that corresponds to the UpdateQuery data contract. This can be done directly in a string variable, although a much more secure and convenient way of doing this would be to create an instance of the UpdateQuery class, fill out its properties and then serialize it to a string.

Implementation the request for adding a record

// Instance of the request class. var updateQuery = new UpdateQuery() { // Root schema name. RootSchemaName = "Contact", // New column values. ColumnValues = new ColumnValues() { // Key-value collection. Items = new Dictionary() { // [Email] column. { // key.

"Email", // Value — instance of object schema request class. // Configuration of [Email] column. new ColumnExpression() { // Type of expression of obkect schema query — parameter. ExpressionType = EntitySchemaQueryExpressionType.Parameter, // Query expression parameter. Parameter = new Parameter() { // Parameter value. Value = "[email protected]", // Parameter data type — string. DataValueType = DataValueType.Text } } } } }, // Query filters. Filters = new Filters() { // Filter type — group. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.FilterGroup, // Filter collection. Items = new Dictionary() { // Filter by name. { // Key. "FilterByName", // Value. new Filter { // Filter type — comparison filter. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.CompareFilter, // Comparison type — starts with expression. ComparisonType = FilterComparisonType.Equal, // Expression to check. LeftExpression = new BaseExpression() { // Expression type - schema column. ExpressionType = EntitySchemaQueryExpressionType.SchemaColumn, // Path to column. ColumnPath = "Name" }, // Filtering expression. RightExpression = new BaseExpression() {

// Expression type - parameter. ExpressionType = EntitySchemaQueryExpressionType.Parameter, // Expression parameter. Parameter = new Parameter() { // Parameter data type - text. DataValueType = DataValueType.Text, // Parameter value. Value = "John Smith" } } } } } } }; // Serialization of update query class instance in a JSON string. var json = new JavaScriptSerializer().Serialize(updateQuery);

Here, an instance of the UpdateQuery class is created. In the ColumnValues property, the "[email protected]" value is set for the [ Email ] column. To apply this value to a specific record or group of records, specify a link to a correctly initialized Filters class in the Filters property. In this case, a single filter is added to the filters collection to select only records that have the "John Smith" value in the [ Full name ] column.

The next step is to execute DataService POST -query. To do this, create an instance of the < HttpWebRequest class, fill its properties and connect the string with the JSON object created earlier then execute the DataService query and process its result. To do this, add the following source code:

Request implementation

// Converting a JSON object string to a byte array. byte[] jsonArray = Encoding.UTF8.GetBytes(json); // Creating an insrance of HTTP request. var updateRequest = HttpWebRequest.Create(updateQueryUri) as HttpWebRequest; // Defining a request method. updateRequest.Method = "POST"; // Determining type of request content. updateRequest.ContentType = "application/json"; // Adding authentication cookie received earlier to a request. updateRequest.CookieContainer = AuthCookie; // Set length for request content. updateRequest.ContentLength = jsonArray.Length;

// Putting BPMCSRF token to the request header. CookieCollection cookieCollection = AuthCookie.GetCookies(new Uri(authServiceUri)); string csrfToken = cookieCollection["BPMCSRF"].Value; updateRequest.Headers.Add("BPMCSRF", csrfToken);

// Plase a JSON-object to request content. using (var requestStream = updateRequest.GetRequestStream()) { requestStream.Write(jsonArray, 0, jsonArray.Length); } // Executing HTTP request and getting a response from server. using (var response = (HttpWebResponse)updateRequest.GetResponse()) { // Displaying response in console. using (StreamReader reader = new StreamReader(response.GetResponseStream())) { Console.WriteLine(reader.ReadToEnd()); } }

Delete a record in the [Contacts] section

Advanced

Example. Create a console application that, using the DataService service, will delete the "John Best" contact record added in the example.

Example implementation algorithm

1. Сreate and configure a C# console application project Using the Microsoft Visual Studio (version 2017 and up) development environment, create a Visual C# console application project and name it DataServiceDeleteExample. The Target framework project property must be set to .NET Framework 4.7.

In the References section of the project you need to add dependencies of the following libraries:

System.Web.Extensions.dll is a class library included in the .NET Farmework

Terrasoft.Core.dll is a main class library of the application server kernel. Can be found by the following path: [Directory with the installed application]\Terrasoft.WebApp\bin\Terrasoft.Core.dll

Terrasoft.Nui.ServiceModel.dll class library the application services. Can be found by the following path: [Directory with the application installed]\Terrasoft.WebApp\bin\Terrasoft.Nui.ServiceModel.dll .

Terrasoft.Common.dll is a main class library of the application server kernel. Can be found by the following path: [Directory with the installed application]\Terrasoft.WebApp\bin\Terrasoft.Common.dll .

Add using directives to the application source code file:

Adding using directives

2. Add field declarations and constants to the application source code To access the DataService features, you must add the fields and constants to the application source code.

Adding the fields and constants

// Main Creatio URL. Has to be changed to a custom one. private const string baseUri = @"http://example.creatio.com"; // Query string to the Login method of the AuthService.svc service. private const string authServiceUri = baseUri + @"/ServiceModel/AuthService.svc/Login"; // DeleteQuery query path string. private const string deleteQueryUri = baseUri + @"/0/DataService/json/reply/DeleteQuery"; // Creatio cookie authentication. private static CookieContainer AuthCookie = new CookieContainer();

Three string constant fields that are used to carry out the authentication requests and requests to read data are declared here. The authentication data will be stored in the AuthCookie field.

3. Add a method that performs authentication in the Creatio application You need to authenticate the newly created application to access the DataService web service.

4. Implement a query to add a record

As the previously declared updateQueryUri constant contains the path for sending data in JSON format, the data sent must be pre-configured in the form of a string containing a description of the JSON object corresponding to the UpdateQuery data contract. This can be done directly in a lowercase variable but it is much easier and safer to create an instance of the UpdateQuery class, fill its properties, and then serialize it to a string.

Implementation the request to adding a record

// Query class instance.

var deleteQuery = new DeleteQuery() { // Root schema name. RootSchemaName = "Contact", // Query filters. Filters = new Filters() { // Filter type — group. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.FilterGroup, // Filter collection. Items = new Dictionary() { // Filtration by name. { // Key. "FilterByName", // Value. new Filter { // Filter type — comparison filter. FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.CompareFilter, // Comparison type — starts with an expression. ComparisonType = FilterComparisonType.Equal, // Expression to be checked. LeftExpression = new BaseExpression() { // Expression type — schema column. ExpressionType = EntitySchemaQueryExpressionType.SchemaColumn, // Column path. ColumnPath = "Name" }, // Filtration expression. RightExpression = new BaseExpression() { // Expression type — parameter. ExpressionType = EntitySchemaQueryExpressionType.Parameter, // Expression parameter. Parameter = new Parameter() { // Parameter data type — text. DataValueType = DataValueType.Text, // Parameter value. Value = "John Best" } } } } }

} }; // Class instance serialization of the JSON string adding query. var json = new JavaScriptSerializer().Serialize(updateQuery);

This creates an instance of the DeleteQuery class. The Contact value is set in the RootSchemaName property. To delete a particular record or group of records, you need to set a link to the correctly initialized Filters class instance to the Filters property. In this case, a single filter that selects only records with the John Best value in the [ Full name ] column is added to the filter collection.

In the final step you must perform POST query to the DataService service. To do this, create an instance of the HttpWebRequest class, fill in its properties, attach a previously created string with the JSON object to a request, and then execute and process the result of the query to the DataService service. To do this, add the following source code:

Request implementation

} }

Add and update a record in the [Contacts] section

Advanced

Example. Create a console application that will use DataService to:

add a contact record with the value "John Smith" in the [ Full name ] column;

change the value of the [ Business phone ] column to 012 345 67 89 for all contact records that have "John Smith" as the value in the [ Full name ].

Records must be added and modified via a batch query.

Example implementation algorithm

1. Create and set up a C# application project Using the Microsoft Visual Studio development environment (version 2017 and up), create a Visual C# console application project and specify the project name, for example, DataServiceBatchExample . Set ".NET Framework 4.7" for the project property Target framework .

In the References section of the project, add dependencies from the following libraries:

System.Web.Extensions.dll – class library included in .NET Framework;

Terrasoft.Core.dll – library of base Creatio server core classes. It can be found using the following path: [Creatio setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Core.dll ;

Terrasoft.Nui.ServiceModel.dll — application service class library. It can be found using the following path: [Creatio setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Nui.ServiceModel.dll ;

Terrasoft.Common.dll – library of base Creatio server core classes. It can be found using the following path: [Creatio setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Common.dll .

Add the using directives to the application source code file.

Adding the using directives

using System; using System.Text; using System.IO; using System.Net;

using System.Collections.Generic; using Terrasoft.Nui.ServiceModel.DataContract; using Terrasoft.Core.Entities; using System.Web.Script.Serialization; using Terrasoft.Common;

2. Add fields and constants and field declarations to the source code To access DataService features, add the fields and constants to the application source code.

Adding the fields and constants

// Primary URL of Creatio application. Must be replaced with a custom one. private const string baseUri = @"http://example.creatio.com"; // Request string to the Login methid of the AuthService.svc service. private const string authServiceUri = baseUri + @"/ServiceModel/AuthService.svc/Login"; // Path string for the BatchQuery. private const string batchQueryUri = baseUri + @"/0/DataService/json/reply/BatchQuery"; // Creatio authentication cookie. private static CookieContainer AuthCookie = new CookieContainer();

Here, three string fields are declared. These fields will be used to form authentication query and read data queries execution paths. Authentication data will be saved in the AuthCookie field.

3. Add method that performs Creatio application authentication Authentication is required to enable access of the created application to the DataService.

4. Implement query adding request

Because the batchQueryUri constant declared previously earlier contains a path for sending data in the JSON format, sent data must be configured beforehand as a string that contains a JSON object description. Use data contract classes to create separate queries then serialize them in a string.

For a query to add a contact record with the name "John Smith", add the following program code:

Implementation the request for adding a record

// Insert query. var insertQuery = new InsertQuery() { RootSchemaName = "Contact", ColumnValues = new ColumnValues() { Items = new Dictionary() {

{ "Name", new ColumnExpression() { ExpressionType = EntitySchemaQueryExpressionType.Parameter, Parameter = new Parameter { Value = "John Smith", DataValueType = DataValueType.Text } } } } } };

To change the value of the [ Business phone ] column to 012 345 67 89 for all contact records that have "John Smith" value in the [ Full name ] column, add the code.

Implementation the request for updating a record

// Update query. var updateQuery = new UpdateQuery() { RootSchemaName = "Contact", ColumnValues = new ColumnValues() { Items = new Dictionary() { { "Phone", new ColumnExpression() { ExpressionType = EntitySchemaQueryExpressionType.Parameter, Parameter = new Parameter() { Value = "0123456789", DataValueType = DataValueType.Text } } } } }, Filters = new Filters() { FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.FilterGroup, Items = new Dictionary()

{ { "FilterByName", new Filter { FilterType = Terrasoft.Nui.ServiceModel.DataContract.FilterType.CompareFilter, ComparisonType = FilterComparisonType.Equal, LeftExpression = new BaseExpression() { ExpressionType = EntitySchemaQueryExpressionType.SchemaColumn, ColumnPath = "Name" }, RightExpression = new BaseExpression() { ExpressionType = EntitySchemaQueryExpressionType.Parameter, Parameter = new Parameter() { DataValueType = DataValueType.Text, Value = "John Smith" } } } } } } };

After serializing the created instances of the query class, add information about the qualified name of the corresponding data contract to the strings with JSON objects. Compose the string with batch query.

Batch query

// Serialization of update query class instance in a JSON string. var jsonInsert = new JavaScriptSerializer().Serialize(insertQuery); // Inserting query type in a JSON string. jsonInsert = jsonInsert.Insert(1, @"""__type"": ""Terrasoft.Nui.ServiceModel.DataContract.InsertQuery""," // Serialization of instance of the update query class in a JSON string. var jsonUpdate = new JavaScriptSerializer().Serialize(updateQuery); // Inserting query type in a JSON string. jsonUpdate = jsonUpdate.Insert(1, @"""__type"": ""Terrasoft.Nui.ServiceModel.DataContract.UpdateQuery""," // Creating batch query. var json = @"{""items"": [" + jsonInsert + "," + jsonUpdate + "]}";

The next step is to execute the POST DataService query. To do this, create an instance of the HttpWebRequest class, fill its properties and connect the string with JSON object, created earlier, then execute the DataService query and process its result. To do this, add the source code.

Request implementation

// Converting a JSON object string in a byte array. byte[] jsonArray = Encoding.UTF8.GetBytes(json); // Creating an instance of HTTP request. var batchRequest = HttpWebRequest.Create(deleteQueryUri) as HttpWebRequest; // Defining request method. batchRequest.Method = "POST"; // Determining request content. batchRequest.ContentType = "application/json"; // Adding authentication cookie received earlier to a query. batchRequest.CookieContainer = AuthCookie; // Set the ContentLength property of the WebRequest. batchRequest.ContentLength = jsonArray.Length;

// Adding CSRF token to the request header. CookieCollection cookieCollection = AuthCookie.GetCookies(new Uri(authServiceUri)); string csrfToken = cookieCollection["BPMCSRF"].Value; batchRequest.Headers.Add("BPMCSRF", csrfToken);

// Adding JSON object to the query contents. using (var requestStream = batchRequest.GetRequestStream()) { requestStream.Write(jsonArray, 0, jsonArray.Length); } // Executing HTTP request and getting reply from server. using (var response = (HttpWebResponse)batchRequest.GetResponse()) { // Displaying response in console. using (StreamReader reader = new StreamReader(response.GetResponseStream())) { Console.WriteLine(reader.ReadToEnd()); } } // Application execution delay. Console.ReadKey();

The object that contains the value of the added column. Has the Object type.

The Filters class C#

The Namespace Terrasoft.Nui.ServiceModel.DataContract .

An instance of the UpdateQuery class must contain a link to a correctly initialized instance of the Filters class in the Filters property. Otherwise, new column values from the ColumnValues property will be set for ALL section records.

DeleteQuery class C#

Advanced

The Namespace Terrasoft.Nui.ServiceModel.DataContract .

The DeleteQuery contract is used to delete sections. The data is transferred to the DataService via HTTP by using the POST request with the following URL:

The structure of request for deleting data

// URL format of the POST query to DataService to delete data. http(s)://[Creatio application address]/[Configuration number]/dataservice/[Data fromat]/reply/DeleteQuery

An example the request for deleting data

// URL example of the POST query to DataService to delete data. http(s)://example.creatio.com/0/dataservice/json/reply/DeleteQuery

The DeleteQuery data contract has a hierarchical structure with multiple nesting levels. In the Creatio application server part, the DeleteQuery data contract is represented by the DeleteQuery class of the Terrasoft.Nui.ServiceModel.DataContract namespace of the Terrasoft.Nui.ServiceModel.dll class library. However, for simplicity, the hierarchical structure of the DeleteQuery data contract is conveniently presented as a JSON format object:

Structure of the DeleteQuery data contract

{ "RootSchemaName":"[Root schema]", "OperationType":[Record operation type], "ColumnValues":[Column values. Not used.], "Filters":[Query filters] }

Properties

RootSchemaName string

A string containing the name of the root object schema of the added record.

OperationType QueryOperationType

Operation type is set by the QueryOperationType namespace Terrasoft.Nui.ServiceModel.DataContract namespace enumeration value. For the SelectQuery the QueryOperationType.Select value is set.

Possible values ( QueryOperationType )

Select 0

Insert 1

Update 2

Delete 3

Batch 4

ColumnValues ColumnValues

Contains a collection of column values of the added record. Inherited from the BaseQuery parent class. Not used in this type of queries.

Filters Filters

Query filter collection. Its Filters type is defined in the Terrasoft.Nui.ServiceModel.DataContract namespace.

The Filters class C#

The Namespace Terrasoft.Nui.ServiceModel.DataContract .

The DeleteQuery query class instance must contain a link to the correctly initialized Filters class instance in the Filters property. Otherwise ALL section records will be deleted.

Batch queries C#

Advanced

Batch queries are used to minimize requests to DataServise, which improves application performance. Packet query is a collection that contains a custom set of DataService requests. The query data is transferred to DataService via HTTP, with the help of POST by the URL.

The structure of batch query

// URL format of the batch POST query to DataService. http(s)://[Creatio application address]/[Configuration number]/dataservice/[Data fromat]/reply/BatchQuery

An example the batch query

// URL example of the batch POST query to DataService.

http(s)://example.creatio.com/0/dataservice/json/reply/BatchQuery

The data that comprises a batch query can be passed in different formats. One of the more convenient formats is JSON.

The structure of a batch query in JSON format

{ "items": [ { "__type": "[Full qualified name of the query type]", //One-time query contents. ... }, // Other one-time queries. ... ] }

To generate the contents of one-time queries that comprise a batch query, use the following data constants: InsertQuery , SelectQuery , UpdateQuery and DeleteQuery .
