Twitch Tv documentation gives example of finding user_id
curl -H 'Accept: application/vnd.twitchtv.v5+json' \
-H 'Client-ID: uo6dggojyb8d6soh92zknwmi5ej1q2' \
-H 'Authorization: OAuth cfabdegwdoklmawdzdo98xt2fo512y' \
-X GET 'https://api.twitch.tv/kraken/user'
but I just want to use the client_id …
How to get the user_id with only client_id?
