As per the docs
You need to specify a ClientID as a header, browsers won’t do that “outta the box”
Or you need to specify the oAuth as a Authorization header
curl -H 'Authorization: Bearer cfabdegwdoklmawdzdo98xt2fo512y' \
-X GET 'https://api.twitch.tv/helix/users?id=44322889'
For example
You could of used any posting tool/client Testing tool such as Postman
I’m surprised that dashboard doesn’t easily provide the ID for you.
If you provide the bots username I can just look it up for you.
