How to organize the invitation of friends in the mobile version of the game?

Question

Classmates

Greetings to all, there was a question about api classmates.
There are methods for inviting friends ( https://apiok.ru/wiki/display/api/friends.appInvite+ru)
And there is a mobile online game connected via m.ok.ru to classmates.
How to organize the use of this method? This would allow to triple the audience of the project and would significantly help the project as a whole.
We asked the publisher to do this, but as far as we can judge, there is no clear result.

Answer 1

It is highly recommended to use the https://apiok.ru/wiki/pages/viewpage.action?pageId... widget instead of this method, which does the same thing, but does not require permission from us to use the friends.appInvite method, which we give extremely rarely.
