title: Spotify API 400 Error Only Valid Bearer Authentication Supported
body: <p>I'm trying to use the spotify api to get data for my top artists and songs. I followed the authorization code examples here <a href="https://github.com/spotify/web-api-auth-examples" rel="noreferrer">https://github.com/spotify/web-api-auth-examples</a>. The authorization works and I can log in and see my basic info and now I'm trying to get my top artists however I get a 400 error: "Only valid bearer authentication supported". </p>
  
  <p>Here's my code for this</p>
  
  <pre><code>    app.get('/get_top_artists', function(req, res) {
    var authString = 'Basic' + new Buffer(client_id + ':' + client_secret).toString('base64')
    var authOptions = {
      url: 'https://api.spotify.com/v1/me/top/artists',
      headers: {
        'Authorization': authString
      }, function(res) {
        console.log(res)
      }
    };
  
    request.post(authOptions, function(error, response, body) {
      if (!error &amp;&amp; response.statusCode === 200) {
        var get_top_artists = body.get_top_artists;
        res.send({
          'get_top_artists': get_top_artists
        });
      }
    });
  })
  </code></pre>
  
  <p><strong>EDIT</strong></p>
  
  <pre><code>    app.get('/get_top_artists', function(req, res) {
    console.log('top artists');
  
    var authOptions = {

        form: {

          grant_type: 'authorization_code'
        },

            json: true
          };
  
          // use the access token to access the Spotify Web API
