如何在ASP.NET中验证Paypal成功页面

Question

I have a PayPal transaction successful page that I need to store customer data on.

How can I authenticate this page on page load so that it only displays when users come back from a successful PayPal transaction? (you can't just type it in manually in the browser)

Answer 1

I think you can send some custom data parameter to PayPal which PayPal sends as a parameter to your success page. You have to check for the correct value of that parameter in your Page_load event.
