IPN锛?Instant Payment Notification (IPN)

You have turned on the IPN feature. You can view your IPNs on the IPN History page. If necessary, you can resend IPN messages from that page. For more information on using and troubleshooting this feature, read more about Instant Payment Notification (IPN).

Your listener must respond to every IPN message it gets, whether you take action on it or not. If you do not respond, PayPal assumes the IPN was not received and re-sends it. Further, PayPal continues to re-send the message periodically until your listener responds, although the interval between retries increases with each attempt. An IPN will be resent for up to four days, with a maximum of 15 retries.
