The following information should assist you in setting up the osCommerce shopping cart software to work with our service.
There is a module that has been developed for osCommerce that is needed to work with 2Checkout. This module is absolutely necessary to be compliant with our system. You may find this module at the following URL:
It is a common problem to have the sales work in the 2CO account but not the osCommerce cart after a sale. This is because there has to be a return URL set up in your account to tell the 2CO system were to send the sale information after it is placed. osCommerce needs this information to correctly process and finish the sale on your end. This URL can be set up on the Look & Feel setting page of the 2CO Classic Sellers Area (V2). You will find this link under the Helpful Links section of your account homepage. This URL can also be setup on the new VA sellers area Site Management page.
The URL below must be in both the Pending and Approved URL boxes. If you installed OSC to a directory other than the default directory, you will need to use that directory structure here. Be sure to replace “www.your-domain.com” with your actual domain name.
