Get the broadcaster_id and the user_id of any channel with the name

But this token is the same token that i am using to do all the others endpoints in the headers or it’s another ???
because i do this in the other endpoints and it works
let headers = new HttpHeaders();
headers = headers.set(‘client-id’, this.apiKey);
headers = headers.set(‘Authorization’, “Bearer” + ’ '+ accesToken);

And I supose that i can do this endpoint for two random channels no and not mine?

Thank you for all
