Paypal IPN (Instant Payment Notification) is PayPal's push notification service that sends a notification when a transaction is created or has a status change

Paypal Instant Payment Notification (IPN) is PayPal's push notification service that sends a regular HTTPS POST request to a URL you designate in your PayPal account, or when you make certain API calls. PayPal will then notify you when a transaction is created or its status changes (i.e. a dispute is opened).

Common events that can trigger an IPN notice

  • payments
  • Credit Card payments
  • Credit Card disputes
  • PayPal disputes (where PayPal was the payment method)
  • Dispute settlement
  • echeck payment clearance (a PayPal payment status change)
