I am trying a simple request to get some user by ID as specified in the API reference guide([https://dev.twitch.tv/docs/api/reference/#get-users](https://dev.twitch.tv/docs/api/reference/#get-users)). I have tried the GET request in a REST console with `Authorization` as the header name and `Bearer myclientid` as the header value and I get this response:  
{  
“error”: “Unauthorized”,  
“status”: 401,  
“message”: “Must provide a valid Client-ID or OAuth token”  
}

I tried on my linux machine to do the following and get the same response:

curl -H ‘Authorization: Bearer myclientid’ -X GET ‘[https://api.twitch.tv/helix/users?id=44322889](https://api.twitch.tv/helix/users?id=44322889)’

I’ve gone to my dashboard and triple checked my client id to make sure it’s correct. I’ve also tried using the Client ID of an entirely different project I had created years ago. What am I doing wrong?

Bearer is for authorized keys not for clientID’s

For ClientID just send

> curl -H ‘Client-ID: myclientid’ -X GET ‘[https://api.twitch.tv/helix/users?id=44322889’](https://api.twitch.tv/helix/users?id=44322889%E2%80%99)

Thank you so much. I spent way too long trying to figure that out. Maybe the documents should mention this…

The Docs do explain this.

In the Getting Started section of the API docs [Twitch API | Twitch Developers](https://dev.twitch.tv/docs/api/) the second step shows how to use your Client ID to make requests.

Also in the Guide section of the API docs [Twitch API Concepts | Twitch Developers](https://dev.twitch.tv/docs/api/guide/#authentication) it explains authentication and how User Access and App Access tokens are sent in requests.
