How can I pass a parameter to paypal (clicking buy now button) and receive it back after successful payment?

[Duaa Momani]

I am trying to add a paypal (buy now button) into my facebook application. I need to send the user's ID into the paypal page, and do some code for that same user after he/she submit payment.

That means:
facebook ----ID---> paypal ---ID---> successful link

Is there a way to do that?

Thanks a lot!

That's a great question for PayPal's Consumer Tech department. You can reach them at 1-888-221-1161.

Hope this helps!
