Question

Classmates

Dear users and guests, MB, who knows how you can still perform this action., For example:
www.ok.ru/group/52814902993802 - (Full version
) not by 52814902993802.

Answer 1

For most applications, the id is real and the same in the api.
For applications with non-zero encoding seed, you can get id like this: real = encoding seed ^ received from api
