Setting up a notification on batch change

The payment gateway notifies on the merchant website in the following cases:

When a transaction expires.
This is the case of transactions created in manual validation mode and that have not been validated in time by the merchant. The status of these transactions changes to "Expired" (EXPIRED).
When a PayPal transaction that has been blocked due to suspected fraud is finally accepted or refused.
The status of the concerned transactions changes from "Control in progress" (UNDER_VERIFICATION) to "Captured" (CAPTURED) or"Refused" (REFUSED).

This rule is disabled by default.

Right-click Instant Payment Notification URL on batch change.
Select Manage the rule.
Enter the E-mail address(es) to notify in case of failure field in the "General settings” section. To specify several e-mail addresses, separate them with a semi colon (;).
To allow the platform to automatically resend the notification in the event of failure, check the Automatic retry in case of failure box. This mechanism allows up to 4 attempts to be made.
For more information, see Automatic retry in case of failure.
