Notifications of “Notification URL call” type (IPN)

The Notification URL is the URL of a dedicated page on the merchant website that is automatically called by the payment gateway when specific events take place.

By default, the rules are created to manage the events below:
  • end of payment (accepted or rejected),
  • payment abandoned or canceled,
  • token creation or update,
  • recurring payment creation,
  • new installment date,
  • authorization made in case of a deferred payment,
  • update of a transaction status by the acquirer,
  • operation made via the Merchant Back Office (cancellation, refund, duplication, manual payment, etc.).

These rules must be enabled and configured according to the needs of the merchant (see chapter Setting up notifications).

With each call, the payment gateway transmits transaction details to the merchant website. This is called instant notification (or IPN as in Instant Payment Notification).

To guarantee the security of the exchange, the data is signed with a key known only to the merchant and the payment gateway.
