IPN Overview :

  • PayPal Instant Payment Notification is a call back system that will get initiated once a transaction is completed(eg: When ExpressCheckout completed successfully).
  • You will receive the transaction related IPN variables on your IPN url that you have specified in your request.
  • You have to send these IPN variables back to PayPal system for verification. Upon verification, PayPal will send a response string with "VERIFIED" or "INVALID".
  • If your server fails to respond with a successful HTTP response, PayPal will resend this IPN either until a success is received or up to 16 times.

How to run?

  • IPN Listener script samples are provided for different languages.
  • Deploy IPN Listener script in Cloud environment or you can expose your server port using any third party LocalTunneling software, so that you can receive PayPal IPN call back.
  • Make a PayPal API call (eg: DoDirect Payment request), setting the IpnNotificationUrl field of the API request class to the url of deployed IPN Listener script.
  • You will receive IPN call back from PayPal.
