What is PayPal IPN?
With the help of Instant Payment Notification, PayPal Sends a GET request directly to a notification URL. The buyers are generally oblivious to it because the whole procedure takes place in the background. It is easy to configure and set up. It generally takes less than 15 minutes to set things up.
When payments are stalled or approved, canceled or chargebacks payments, then merchants can automate order deliveries. The notification was received for each one of them. eCheque payments updates are also posted as notifications. Background access to URL notification is instant after being updated on new transactions.
It is necessary to be sure about not processing orders in duplicate because duplicate notifications are failed to send. Notification URL is hidden from other users and customers, which helps keep things in secure and order. In the background, notifications can be processed, and updates or respective emails can be made.
When IPN is used all alone, with email customers can only be notified because there is no other way to show order information or download them on the web page. It requires more code for verification and checks to discard certain notifications and pay attention to important ones.
