PayPal Order Management Integration Guide PDF document. © 2008 PayPal, Inc. This document is written for merchants who use PayPal to manage order information. This document describes the PayPal features for managing orders, such as Payment Data Transfer ( PDT ), Instant Payment Notification ( IPN ), and Downloadable History Log. PayPal is the faster, safer way to pay and get paid online. The service allows people to send money without sharing financial information. PayPal supports payments in 25 currencies including: U.S. Dollar, Australian Dollar, Canadian Dollar, Hong Kong Dollar, Singapore Dollar, Taiwan New Dollar, New Zealand Dollar, Euro, Swiss Franc, Czech Koruna, Swedish Krona, Danish Krone, Norwegian Krone, Hungarian Forint, Mexican Peso, Philippine Peso, Malaysian Ringgit, Chinese RMB, Israeli New Shekel, Pounds Sterling, Brazilian Real, Polish Zloty, Thai Baht, Turkish Lira and Japanese Yen. PayPal offers four payment notification methods for back-end integration: Email, Reporting, Instant Payment Notification ( IPN ), Payment Data Transfer ( PDT ). PDT's primary function is to display payment transaction details to buyers when they are automatically redirected back to your site upon payment completion. Both IPN and PDT send back the same data; however, there are several important differences. The most important: with PDT, it is possible to miss a notification if the user closes the browser before the redirection is complete, while with IPN at the end of the website payment flow, PayPal POSTs the IPN data asynchronously ( i.e. not as part of the website payment flow ). What does it mean? It is simple: PDT perhaps will send you a notification, while IPN will always send you a payment notification. For this reason, or if you are using this data to fulfill orders ( in a database environment, for example ), PayPal strongly recommends that you also enable Instant Payment Notification ( IPN ). Because credit card and bank information is not transmitted in Instant Payment Notification ( IPN ), PayPal does not require Secure Sockets Layer ( SSL ) to encrypt IPN transmissions.
