Invalid username - cant get devices

[nogetfx]

Hi

I'm trying get Spotify devices (and eventually set active device) via the web API. I can retrieve track info, but as soon I try to access device or play/pause I get the "Invalid User" reply.

I can see the necesary scopes in the Auth token reply, but I'm missing something.

'token_type': 'Bearer', 'expires_in': 3600, 'scope': 'user-modify-playback-state user-read-playback-state user-read-currently-playing user-read-recently-played'}

In other posts the Spotify username is mentioned as a possible error. I use same account in Home assistant and can play/pause with no errors.

Thanks

    def _set_device(self, *args):
        BASE_URL = 'https://api.spotify.com/v1/'
        DEV_URL = "me/player/devices"
        AUTH_URL = 'https://accounts.spotify.com/api/token'

        auth_response = requests.post(AUTH_URL, {
            'grant_type': 'client_credentials',
            'client_id': '..',
            'client_secret': '..',
            'scope': 'user-modify-playback-state user-read-playback-state user-read-currently-playing user-read-recently-played',
        })

        auth_response_data = auth_response.json()
        access_token = auth_response_data['access_token']

        headers = {
            'Authorization': 'Bearer {token}'.format(token=access_token)
        }
        track_id = '7I6y2ptp8e5zTIxmv8uEjP'
        #r = requests.get(BASE_URL + 'audio-features/' + track_id, headers=headers)
        #r = requests.get(BASE_URL + 'me/player/devices', headers=headers)
        r = requests.get('https://api.spotify.com/v1/me/player/pause', headers=headers)

Welcome to the forum, @nogetfx!

It looks like you're using the client credentials flow to authenticate with Spotify. In order to use the player endpoints, you'll want to obtain a token through one of the other OAuth flows, like the authorization code flow. You can find more information about this in our OAuth documentation: https://developer.spotify.com/documentation/general/guides/authorization-guide/
