Question

I made a script for IPN which works great but how can i immediately notify the user?

I mean paypal redirects the customer to a custom-page i can define, simultanously my ipn.php checked the status,

BUT how can i immediately tell the customer on this custom-page that it was successful or not.

this custom-page does somehow has to know that this is the customer-xyz which made the ipn-verified!!! payment xyz, but how? i think also this custom-page redirect should wait the 5 seconds because php does only process files/request on-loads… so after 5 seconds the ipnscript surely did complete.

Sorry if this question is too newby but i dont know how to notify the customer about the (ipn-verified!!!) payment-status immediately.

How do you do this?

Thanks so much

When a customer is redirected to your “return” page, you can use PDT (which is much the same process as IPN) to determine which transaction has completed.

You need to use IPN to action the purchase (as the user could close their web browser before returning to your website, and thus never see the return page). You can then use PDT to confirm the transaction and thank the user for their purchase, give them access to anything that they can then download, display their package tracking details, or whatever.
