How to find out your balance on a Sberbank account/card via API?

Question

API

Sberbank has a mobile application in which you can see the balance of your accounts / cards. It turns out that Sberbank has an API.
There is a zenmoney.ru service for accounting finance (personal accounting), which has the ability (in a mobile application) to synchronize with Sberbank. And this is also confirmation that Sberbank has an API.
But nowhere can I find any documentation, or even a discussion about how to implement such a thing myself. The answers I found on the Internet only say that Sberbank does not have such an API, you can get information about the balance on accounts / cards via SMS requests, but somehow zenmoney.ru implemented synchronization with Sberbank. But although, as I understand it, the zenmoney.ru application “pretends to be” an application from a savings bank during synchronization, but I think this is not a problem and most likely you just need to set the “correct” user-agent.
Where can I find documentation on how to find out the balance on an account/card and get the latest transactions on these Sberbank accounts/cards via API?

Answer 1

Have you tried to create an account like "connection to the bank" in Zenmoney and choose Sberbank? He asks for a login, password and pincode, i.e. just imitates their mobile application for android (specifically for android, Sber, apparently, has different APIs for different platforms).
It looks like the guys just sniffed the requests of the original application and filed a plugin for themselves .
