The notification contains transaction outcome information and is sent by the XPay gateway in server-to-server mode with the POST method, in JSON format.
The notification is optional, it is sent if the "notificationUrl" parameter is set in the APIs:
- POST /orders/hpp (Hosted Payment Page)
- POST/orders/paybylink (Pay-By-Link)
- POST /orders/build (XPay Build)
It is possible to check the IP addresses from which notifications are sent and the user agent used by the gateway, in the Service Usage Specifications section.
