I have an Shopping Cart in ASP.NET. And I need to integrate PayPal as Payment Gateway with PayPal IPN. How can I do it ?? I need ConfirmationIPN.aspx file and tell me how to pass the parameter to PayPal for IPN.
If I get Complete Shopping Cart in ASP.NET then its great.

Please refer to this thread:
If you're working with paypal sandbox, you need to make two accounts on their test site. One for a buyer and one for a seller. Then use the "demo" credentials when testing this stuff.
