Abnormal Payment Callback Notification
Webhook
When the abnormal order status changes to success or failure, the merchant will receive a callback notification, and the merchant needs to update the local order status based on the callback notification.
Merchant can add an abnormal payment callback address (HTTPS protocol URL accessible from the public network) in the institutional information of Pay Protocol management backend. When an abnormal payment is detected, the system will send an abnormal order notification to this URL.
The callback will be sent up to 6 times, respectively at 0 seconds, 15 seconds, 30 seconds, 3 minutes, 5 minutes, and 10 minutes after the abnormality is confirmed.
When the merchant returns success normally, the system will consider the callback successful and will not send subsequent callbacks.
Note: The merchant needs to verify the signature of the callback notification to ensure the security of the notification. The signing method of the callback is consistent with the normal request.
