Shared with Merchant Clients. 2 Notifications For a list of notifications and order states please refer to the States & Events page at https://docs.gointerpay.net/display/PUB/States+and+Events. ​ Notifications are sent via HTTP POST to a merchant-specified URL. The content of the HTTP POST is signed JSON which must be validated against the signature as follows: 1. Compute the SHA-256 HMAC value of the JSON entity using the shared secret; 2. Base-64 encode the result, and compare this to the specified Signature header. GoInterpay considers a notification delivered when it receives an HTTP 200 OK response. Notifications are re-sent until an HTTP 200 OK response is received. The HTTP Date header specifies the date and time the notification was generated. If a notification is received out of order or is unknown, the merchant should still produce an HTTP 200 OK but ignore the notification.
