How to process the response from the payment system?

Question

1C-Bitrix

There is a task to process the response from the payment system.
Specified a link for the handler - /bitrix/tools/sale_ps_result.php I
created my own handler, but the response to the processRequest method of my handler does not come.
I started to find out, it turned out that the system calls the processRequest method in the file /bitrix/module/sale/lib/paysystem/service.php

How can I redirect the output to my handler?
