Callback URL requirements

In order to receive and process transaction status updates via webhooks, you need to provide us with the callback URL. The requirements for the callback URL are:

  1. You can use any URL as a destination for events. However, the provided URL should be a dedicated page on your server.
  2. The provided URL must be able to accept HTTP POST requests.
  3. We're expecting to get a 200 OK status code when we send a callback with transaction updates. If we receive this status, we will decide that the callback was delivered and won’t send it again.

Otherwise, we will continue sending callbacks for a maximum of 23 times every hour until we receive 200 OK.
