How to check the balance of an MTS SIM card in PHP?

Question

PHP

Dear colleagues!
Task : periodically automatically check the balance of the phone (corporate account) using a web server with PHP and Curl. To display the remainder in the interface of the internal application.
The links that exist today in Google and Yandex lead to resources that describe a simple solution to the problem, but none of them takes into account today's realities. MTS has changed the login principle and updated the pages so that the solutions presented on the network do not work.
If someone has already solved this problem, I beg you to share the implementation in PHP or Bash.

Answer 1

They have a Personal Account and a mobile application. There is a balance available.
A. Solution through the "Personal Account"
1. imitate a login to your personal account using curl, saving cookies and other tinsel
2. simulate a request to your personal account to the balance page using curl
most likely this page contains a balance
3. parse HTMl balance via XML or
