Stage 2

If the initial notification fails, the subsequent two (2) IPN messages are sent after 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.
