However, other actions can trigger IPNs. For example, your site's back-office process might invoke a PayPal API that refunds a payment, or a customer might notify PayPal of a disputed charge.</p> <p>You receive and process IPN messages with a listener (sometimes called a handler). This listener is basically a web page or web application that you create on your server that is always active and had code that allows it to accept and verify IPN messages sent from PayPal, and then invoke backend services on your server, based on the information from the IPN message. The web application waits for IPNs and (typically) passes them to an administrative process that responds appropriately. PayPal provides sample code that can be modified to implement a listener that handles the IPN sent from messages PayPal.
