Paypal checkout does not have IPN feature

[usamaabaid]

I am looking at PayPal Checkout as described at Sample code for PayPal Checkout. There are only 2 JavaScript methods involved with this form of PayPal payment page, which are createOrder and onApprove.

I was expecting a way of specifying IPN which is easily available with PayPal Standard button.

Question

Is IPN feature available in PayPal Checkout and if no, then what would be the best way of implementing something like IPN?

I am thinking of using sample code as below to mimic IPN feature functionality.

onApprove: function(data, actions) {
return actions.order.capture().then(function(details) {
// Show a success message to the buyer
//alert('Transaction completed by ' + details.payer.name.given_name + '!');

//IPN implementation as below
//Instead of showing a message to the buyer, redirect to a success page
//and pass query string variables to pass data from payment page top success page
window.location = "https://www.somesitexyzabc.com/success?s=1&d=abc";
});

If anyone facing same issue i have found the solution which is below.

IPN is very old. PayPal Checkout with Orders v2 doesn't use IPN. There's no purpose for it.

To record transactions on your server, do the capture on your server.

I think you'll need two routes, one for 'Create Order' and one for 'Capture Order', documented here: https://developer.paypal.com/docs/business/checkout/server-side-api-calls/#server-side-api-calls

Pair your two routes with the following approval code: https://developer.paypal.com/demo/checkout/#/pattern/server

When a capture is successful within your server, do whatever you need to do with the information you have before returning the JSON to the approve function.
