Using PayPal button to pay for Software?

[mgfranz]

I have written an app that I want the end user to be able to purchase through PayPal, the PayPal button will be integrated into the app itself.  Making the button is easy, but what I need is the end user info on the PayPal purchase page, I will need their name and email.  What is the best way to implement this?

Also, when creating a button, how can I create it where upon successful payment delivery of the "unlock" code will be emailed to them automatically?

Thanks,

Fixed by just directing the buyer to an "Approved" page on my website, they enter their email address and I email them their code.
