For successfully received notification, you need to send code 200 and parameter "OK" in the response. Anything, other than OK will be regarded as failed notification.
The notification will be retried every 2 hours until it is acknowledged as successfully received from the merchant.
We will stop sending the notification after 3 days if it is still not acknowledged as received.
Please contact our Technical support team if you want to use this feature.
