title: Spotipy client_credential_manager no token provided
body: <p>I'm trying to use the Spotify API with the <code>spotipy.py</code> python module. I saw a specific example in several places and everyone says it works. this is the code:</p>
  
  <pre class="lang-py prettyprint-override"><code>CLIENT_ID = '3de0e551d7ad4f53928abdef515150ed'
  CLIENT_SECRET = '6c77d106a8e843508bc7569f9a0f8397'
  USER = 'd03ueir6zw7k1dyywjc97fee2?si=GVU-LsDRTg2vL5KPMTbfJg'
  
  client_credentials_manager = SpotifyClientCredentials(client_id=CLIENT_ID,
                                                        client_secret=CLIENT_SECRET)
  sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)
  sp.trace = False
  
  plists = sp.user_playlists(USER)
  
  print(plists)
  </code></pre>
  
  <p>Of course in the original code, I put my real client id and secret.</p>
  
  <p>However, when I run this code I'm getting an API response that says "No Token Provided".</p>
  
  <pre class="lang-js prettyprint-override"><code>{
    "error": {
      "status": 401,
      "message": "No token provided"
    }
  }
  </code></pre>
  
  <p>I know you need to get permissions for some actions, but I thought the client credentials manager takes care of the permissions for me.</p>
  
  <p>How do I make this code work?
  And what permissions are given to me using the client credentials manager?</p>
