What is Instant Payment Notification (IPN)
The Instant Payment Notification, also known as "IPN", is a method for online retailers to automatically receive backend notifications about purchases in real-time. This allows E-commerce systems the opportunity to store payment transactions, order information and other sales internally. IPN messages can represent payment success or failures and order transaction status changes.
How it works
A PayCafe merchant must first enable the IPN functionality within the Merchant Portal. Once enabled, PayCafe sends notifications of all transaction-related events to the IPN web address, along with the transaction variables. When customers pay for goods or services, PayCafe sends a secure API payload containing transaction information (IPN messages) to the URL.
If you have questions regarding IPN or setup, please submit a support ticket through merchant portal at www.paycafe.com/login/
