All I want to do is to return the email of the user that completes pay transaction… I found this demo over the web but I cant find the link…
don't forget to create paypall sandbox account
So I will need three pages
1. Default.aspx for filling the user email adress and the amount to be send to paypal.
2. Sendpayment.aspx .Sends the data to paypall
3. Paypal .aspx. It is a listener that “listens” paypall transaction status.
• Default.aspx
