I didn't know where to post this, but since this is a tool that can help me in selling my games, I posted it here. ^^
I want to know if anyone has used this, and if yes, then how to use it? I know how to enable the product using my PayPal account, I know how the buyer pays for a product (in this case, the game) etc., but what I couldn't find in the documentation, is how to allow the buyer to download the game immediately after paying, and so that it would be secure.
I have a hunch it has something to do with Instant Payment Notification (IPN), but I'm not sure.
Any ideas?
