To notify the merchant about payment results in real-time the IPS Assist provides the service for synchronous sending the results of the payment to the merchant server. After completion of the buyer payment (by bankcard or by e-cash) the message is being sent to the merchant server via HTTP POST method with parameters of the payment.
In the Personal Account you can specify the URL for sending the results, the type of signature and the secret word.
After you configure and activate the service the results of payments by bankcards and electronic cash will be sent to the enterprise server. The results of payment confirmation, refunds and cancellations are not sent. Also the result of a payment which is closed by timeout is not sent.
Attention! For security reasons results are sent only on ports 443, 8443, 80, 8080. No other ports can be used to receive the results!
To use the service through HTTPS a certificate from the trusted certification authority must be used.
