Paypal add-to-cart
Hi- So I'm building a customer site to sell downloadables through his site, and he wants to use paypal. We need to build some basic account functionality so individuals buying the items create an account first, and we'll track which items were purchased. This means we have to get some reply from paypal when the transaction is done to note a completed transaction. Can I use your free tools to accomplish this? Do I need something else?
