do you mean this, if so where do i add this:
https://id.twitch.tv/oauth2/authorize?client_id=${CLIENT_ID}&redirect_uri=${redirectUrl}&response_type=code&scope=openid+user_read
and the body of the message:
Object {
“error”: “Bad Request”,
“message”: “Missing required parameter "broadcaster_id"”,
“status”: 400,
}
