PayPal Payment Data Transfer to Angular Web App

Question

I got a quick question:

I want to implement a PayPal checkout. I found out I can use PayPal Payment Data Transfer. If somebody pays me I want PayPal to send me some information back like: User_ID and Item_ID.

How do I post this Data in my PayPal Button and how can I consume this data after I got redirected to my page.

Btw I got an AngularJs Web App and I want to consume the return data in my return page Controller.

Answer 1

I found out how to do it:

PayPal Instant Payment Notification: https://developer.paypal.com/docs/classic/products/instant-payment-notification/

You can store your information in the PayPal custom input:

<input type="hidden" name="custom" value="$user_id" />

Consume it in your php listener file:

$custom = $_POST['custom'];
