After confirmation of the transaction by the external payment system, a notification (callback) with the final status of the transaction will be sent to the merchant’s website.
A callback is a POST request containing information about the results of successful and unsuccessful operations, which is sent to special addresses specified by the client and transmits data on a specific transaction in the form of a set of parameters.
The address to which the notification is sent must be provided at the beginning of the integration.
The transaction status is contained in the parameter status.
The status will be sent again until the http code 200 is received with a period of 5 minutes.
