How to authorize a VK account through a third-party API application?

Question

PHP

In general, the need has ripened to receive a token through a third-party application.

I took the first random software, which is authorized through a third-party application, for example, through KATE MOBILE.
Snapped, received requests:
https://oauth.vk.com/token?grant_type=password&cli... - authorization through android applications

https://android.clients.google.com/checkin

https://android.clients.google.com/c2dm/register3

https://api.vk.com/method/auth.refreshToken?receip...
===============
As a result, after the refreshToken, I am given the KATE MOBIle application token

What requests to send androyd client to get a response in the form of a token for receipt?
Maybe there is a ready-made solution, I tried

example

https://github.com/vodka2/vk-audio-token

but did not understand how to send requests to Google.

What is required from the script then?
I insert the log: pass
application id and in echo it gives me the kate mobile token - that's it.

Answer 1

the code from vodka2 is quite working
specifically about requests to google there is an example
https://github.com/vodka2/vk-audio-token/blob/d586...
Well, auth.refreshToken and requests to google are not needed for all methods, only for some, for example, for working with audio.
