How do I get a notification to my site from someone else's PayPal?

Question

PayPal

A long time ago I saw a marketplace plugin for WordPress based on wookomers. If my memory serves me right, that was the case.
The sellers could indicate their paypal. And the platform received a notification after the payment that the order was paid.
I could be wrong, but I think so.
Question.
Can I receive a notification on my site, in fact, from someone else's payment transaction? I don't need a commission, etc. Only a notification, preferably by api, that the order has been paid.
I don't have wordpress or wokomers. I will write the functionality myself, if possible. If not, what is the best way to automate this? To avoid forcing people to manually reconcile payments.

Answer 1

Apparently this possibility was before and remained for old accounts

Answer 2

without access to someone else's account - no ,
either they will register an IPN URL ,
or even add a user with view-only rights to their account and you will go to them

Answer 3

add the notify_url parameter when generating a paypal payment request and implement an IPN notification handler using this URL.
You can generate a link like this - substitute your seller email instead of [email protected] and url instead of https://test.com/notify
