Using Paypal with osCommerce

In this tutorial we will guide you through installing and configuring the Paypal module in osCommerce. This allows you to accept Paypal payments, which is one of the most common tools for online banking and accepting money, with millions of users.  This module does not require users to have a paypal account to check out, and it will allow you to accept major credit cards.

First, we will install the PayPal Website Payments Standard module, then we will view / edit the settings for this module. The official osCommerce documentation states that this module supports these paypal features:

• Sandbox server to perform test transactions
