I have multiple online stores running OSCommerce and ZenCart. I accept credit card payments through a separate gateway and I would like to set all of them up to accept Paypal as well. However, it seems that I can only have one "return URL" and orders are being paid for, but not processed by my shopping carts since users aren't being redirected back to my websites' "checkout_complete" pages.
I'm using Paypal Website Payments Standard and a Business Paypal account.
Can someone provide a solution for this?
