Since its inception in 1998, PayPal has quickly grown to become the global standard for online payments and is constantly expanding into new countries, languages, and currencies.

This book shows developers how to integrate PayPal directly into websites to make use of its payment technologies. This allows developers, no matter what language they program in, to build shopping carts or similar channel products with PayPal as a payment option. Merchants can also use this book to find out the basics of e-commerce, where PayPal fits in, and how they could take a DIY approach to solving their e-commerce needs.
