marekp Posted March 22, 2007 Posted March 22, 2007 Hello everyone, I am seting up my osCommerce site and installed PayPal Credit/Debit Card modul. I am testing it using sandbox. My problem is that when I confirm transaction it takes me to PayPal sandbox to log in for payment but when I try to log in I am geting mesage that "This invoice has already been paid. For more information, please contact the merchant". Is this osCommerce problem or PayPal sandbox problem? Regards, Marek Quote
Jack_mcs Posted March 22, 2007 Posted March 22, 2007 How to fix that is in the documentation of the lastest oscommerce paypal IPN version.

grspec Posted March 22, 2007 Posted March 22, 2007 I am having this same problem and I have followed the instructions in the documentation. Allow duplicate payments is off, I have even gone in and created a new user and verified the new order is number 5 in the db(last order was 4). but when I go to login to sandbox to pay for the invoice I get This invoice has already been paid. For more information, please contact the merchant. Any ideas? Quote
