API Providers Guideанаapi Design
API Providers Guide API Design Prepared By Kin Lane June 2014 Table of Contents Overview of The API Design Space A New Generation Of API Design Developing The Language We Need To Communicate Leading API Definition Formats Building Blocks of API Design Companies Who Provide API Design Services API Design Tools API Design Editors API Definitions Providing A Central Truth For The API Lifecycle Contributing To The Deployment Lifecycle Contributing To The Management Lifecycle Contributing To The Testing & Monitoring Lifecycle Contributing To The Discovery Lifecycle An Evolutionary Period For API Design Overview of The API Design Space In the early days of APIs, everything was just about deploying and consuming—you were doing one or the other. Then by 2006 we saw the stabilization of common API management practices emerge from providers like Mashery, and then 3Scale. Now in 2014 we are stabilizing again, and the API universe is expanding around the area of API design, with new approaches, tools and entire companies emerging to provide services that are dedicated to helping companies design the best APIs they can. I define the world of API design as everything that goes into planning and designing your API, as well as the definition of your API that will eventually be deployed as your production endpoints, drive your documentation, generate the code samples your developers will use to integrate, test, monitor, and allow your API to be foundthrough this lens, API design is fast becoming the driver for all areas of the API lifecycle. Depending on our needs, API design may begin with understanding HTTP, and REST, or may learning more about applying hypermedia as part of your design constraints, or API design might simply be about generating a Swagger definition, so you can generate interactive API documentation. -
