Webhook notifications

To notify a merchant of an accepted payment or of a changed transaction status, PayCross sends POST requests to the URL from notification_url parameter.

PayCross sends notifications when a transaction status is changed to one of pending, expired, failed or successful.

POST requests (notification) include the shop credentials (Shop ID and Secret Key) and a JSON-serialized message with transaction parameters.

Warning

To avoid receiving of fake notifications, always check credentials received. Only successful verifying of these credentials can guarantee that a notification really came from PayCross.
