I have an existing Pay-Per-Click Search Engine. I devloped the entire site myself(It is all In PHP/mySQL), but I do'nt know how to do Paypal IPN. I need to establish instant payment of some sort, and I believe this is the easiest. If you know of any other payment processing system that is free and you can set up, I would love to hear of it.
