Is anyone versed in integrating PayPal into a .NET project? I&#039;ve been studying the text @ and I get more confused the more I look at it.<BR><BR>One thing that really bother me: it appears that a client can make a purchase for something via PayPal and then close their browser so that my site never gets the variables that it was a success. If that is correct, then that is a huge drawback defeating the purpose of automating payments.<BR><BR>I also don&#039;t understand the difference between passing a variable URL link to PayPal to redirect a successful transaction to versus the IPN redirection link that you set-up in your profile on PayPal. Those are two links that redirect the user, but which one is used. The author seems to use both.<BR><BR>My head hurts.
