A callback is a client message on an event that has occurred using an HTTP request. The UAPAY system makes an HTTP request with the POST method to the URL specified by the client. The format of the transmitted data is JSON. The request is signed using a JWT token, more about this here.

Important! To receive a callback from the product environment, you must provide your personal UAPAY manager with the URL to which you want to receive them, and after confirmation, your URL will be included in the list of allowed URLs to receive a callback. |
There is also a guaranteed callback delivery mechanism - in addition to the first delivery attempt, there are 5 more attempts during the next day with intervals between requests - 5 s, 5 min, 1 h, 2 h, 24 h.
