The PayPal Instant Payment Notification (IPN) service allows PayPal to communicate with your website, and mark transactions as complete, failed, refunded, etc.

Note: please replace “yoursite.com” with the appropriate name of your website.
If the PayPal IPN is not working, you can disable IPN verification, which simply disables an extra verification step that is performed when IPN messages are processed.
Important: Since September 30, 2016, PayPal IPN verification requires an SSL certificate.
Contact to your hosting provider if you don’t know how to get one.
