PayPal is a popular payment processor, especially for new site owners. It allows credit card transactions as well as payments from within PayPal itself. There are predominantly two “flavors” of PayPal’s payment processing tools: Website Payments Standard (WPS) and Website Payments Pro (WPP). For our purposes, we’ll be using Website Payments Standard, since there are no setup fees, no extra security setup required, and we can get started right away. In this lesson we'll create test PayPal buyer and seller accounts, set up access to the test sandbox, and make sure it is working properly.
