Chapter 20. PROCESSING CREDIT CARD TRANSACTIONS WITH PERL
Introducing PayPal
If you have a product or service to sell, it makes sense to provide it for sale on the Internet. In the early days of the Internet, many startup companies appeared, promising secure credit card transactions and instant payment transfers to serve a growing digital economy. Since that time, some companies have disappeared but one that has remained viable is PayPal.
PayPal offers multiple solutions and products for both consumers and merchants. You can use PayPal as a financial transaction engine for your Web site, charging credit cards, issuing refunds, transferring funds, and as a database for organizing your orders, transactions, and shipping addresses.
