Business Catalyst End of life announcement - find out more details.

Instant payment notification (IPN) is a method for online retailers to automatically track purchases and other server-to-server communication in real time.

IPN messages can represent a successful or failed payment, order transaction status changes, accounting ledger information and many other possibilities depending on the payment gateway.

When an E-commerce system requests a resource from a payment gateway, like a new invoice or bill for goods, the request must contain a URL endpoint representing a script or program to handle returning notifications. IPN messages are then sent to the retailer's E-commerce system by HTTP POST as the resource is updated by the gateway. The IPN handler usually performs standard actions like validating the message, updating inventory levels in the E-commerce system, notifying customers of successful or failed payments, etc. Depending on the retailer's business requirements and the level of sophistication of the E-commerce software, some or all of the IPN messages can be handled or ignored.

In Business Catalyst, IPN messages are used in integration with PayPal Payment Gateway

In order to enable the IPN messages:

Please notice:

If the IPN is not enabled on your PayPal account used to accept payments from your E-commerce Business Catalyst Site , the Order Status will be

empty and the payment is not registered on the Business Catalyst order.
