To notify the merchant about the payment result in real time, the IPS Assist system provides a service for synchronously sending payment results to the merchant server. After the buyer completes payment for the order (using a bank card or one of the of electronic cash payment means), a message with payment parameters is sent to the merchant server using the HTTP POST or SOAP method.
You can set up sending in your Personal Account by specifying the URL for sending results, protocol type (POST or SOAP), signature type and secret word.
