How to implement fixation of payment or return of an order using the Measurement Protocol?

Question

PHP

Good afternoon.
Help with implementation in php.
It is necessary to send a request to Google Analytics for payment or return of the order upon triggering a certain event (clicking on a button, for example). Transactions have already been created, all products, prices and other necessary information are already present. You need to send 2 events: payment passed or a refund occurred. If the return is more or less clear ( Purchase tracking ), then payment is a problem. I have never worked with Google analytics before and I don’t know if there is such an opportunity at all. Thanks in advance.

but it's better to deal directly with Google,
the main idea is to form a request with fields and POST it to the GA url, the answer is usually 200 if the data passed ok, or not 200 if the data did not pass the
correctness of the data GA does not check, everything is on your side
