PayPal/IPN

Overview

Instant Payment Notification (IPN) is one of two methods by which a web site may retrieve payment information from PayPal in real-time, i.e. immediately after a payment is completed. The other method is Payment Data Transfer (PDT).

IPN is somewhat more reliable than PDT in that PayPal's server contacts the merchant's server directly to transmit transaction data as soon as the transaction has occurred, rather than depending on the customer's browser to convey the data.
