IPN POST failure recovery process



No of attempts

Stage 1

2Checkout sends the first Instant Payment Notification (IPN) instantaneously for events per your account’s Notification Settings.


Stage 2

If the initial notification fails, 2Checkout sends the subsequent two (2) IPN messages within the next five (5) minutes.


Stage 3

If the issue persists, and requests continue to result in failures, 2Checkout makes another four (4) retries, 15 minutes apart.


Stage 4

Following the four tries made in Stage 3, the 2Checkout system performs one-hour interval continuous requests for a maximum of two (2) days after it sent out the initial notification, until a valid response.
