Problem with Channel Subscriber Check

[Ben]

@BarryCarlyon

if you intend to use the API for this, you will require an access token from the broadcaster in order to read that data. The data “blongs to” the streamer/broadcasters so you need the streamer/broadcasters to read that data

So it is not possible for a user to find out whether another user has a sub on the streamer channel? Just about the chat tags?

When i see Chatterino or Chatty what ever. This Tools load all users Subscribtion + Tier 1 or 2 or 3.
Without a Chat Tag. How is this possible? Can I get an accessToken from a user ID even if I’m not that user?
