PayPal TimeOut - DoExpressCheckoutPayment

We are using PayPal on a faily large website, integration went well with all code helpers from the integration wizard. Now we had processed a number of transactions in the first day of putting this live but a small percentage (5%) essentially had there transaction processed by PayPal but our system recieved a TimeOut. I believe this happens at the point where we submit the "DoExpressCheckoutPayment" Method. and because of this the system cannot tell if the payment has been complete or not.

This is a real tough one, as the website has a live currency that we need to update so paypal taking the money but the system not updating is not acceptable.

I'm interested to know if this is a common problem and how we should go about handeling it. I'm doing my best to re-create the issue but cannot at this time.

This looks like a similar problem - https://www.x.com/thread/45136

Any help would be appriciated!

After looking into this in more depth, retry logic is not a good idea as the TimeOut is due to the response (So paypal has most likly credited the account).

Instant Payment Notification (IPN) seems to be the solution.

Add retry logic to your application. This is a common way of handling this problem.
