How to make authorization, and posting in Classmates with embeeded Linux (without a browser)?

Good day,

I develop software to emmbed Linux devices, these devices have browsers to run only 1 app.

At the moment this application is implemented login and posting in the social network Vkontakte API https://vk.com/dev/auth_direct

Read all the documentation https://apiok.ru/ext/oauth/ but not found how to do it (without a browser) and Classmates.

Please tell me

Sincerely,
Andrew
