Hello everyone. I have a question regarding OAuth2.  
I’m using **OAuth implicit code flow** on the app’s frontend. Then I pass fetched token to the python backend where I try to retrieve data about the user.  
I use only “user:read:email” scope.

The issue is that when I call **[https://api.twitch.tv/helix/users](https://api.twitch.tv/helix/users)** like so:

```auto
auth_headers = {
            'Authorization': 'Bearer ' + access_token,
        }
url = 'https://api.twitch.tv/helix/users'
response = requests.post(url=url, headers=auth_headers)

```

I receive `{'error': 'Unauthorized', 'status': 401, 'message': 'Client ID is missing'}`  
If I add `Client-Id=some_cliend_id` to the request headers everything works.

Shouldn’t it work with token only?

No both a ClientID and Bearer token are required/must be specified.
