I found the twitch api library for python, with it you can subscribe to the channel, but for this you need to generate a token and specify scopes
I can’t find suitable scopes in this list
how then to generate a token so that you can force the account to subscribe?
Assuming by “subscribe” you mean “follow” since you referenced the follows scope.
The ability to add/remove follows has been removed from the API. It’s no longer possible to follow or unfollow a channel via the API
Reference: Deprecation of Create and Delete Follows API Endpoints
not via api? selenium? request?
No longer supporte via the API
Technially a violation of the developer agreement, issues with screenscarping and headless interaction aside.
Not sure what you mean here.
