title: Is it possible to pass Facebook Graph API access token through request header?
body: <p>I am testing Facebook Graph API v2.3 with <a href="https://www.getpostman.com/" rel="noreferrer">Postman</a>.
  While it is possible to get response by putting access token in query string as follow: </p>
  
  <pre><code>https://graph.facebook.com/v2.3/me?access_token=my_access_token
  </code></pre>
  
  <p>I am wondering whether it's possible to do the same thing with HTTP request headers, which would be something like this:</p>
  
  <pre><code>GET /v2.3/me HTTP/1.1
  Host: graph.facebook.com
  Authorization: &lt;my_access_token&gt;
  Cache-Control: no-cache
  Postman-Token: &lt;postman_token&gt;
  </code></pre>
  
  <p>Based on this similar question (i.e. <a href="https://stackoverflow.com/questions/16526211/how-should-a-client-pass-a-facebook-access-token-to-the-server">How should a client pass a facebook access token to the server?</a>) on Stackoverflow, it seems that this should be possible. </p>
  
  <p>Any thoughts on this?</p>

    <p>What raised my interest is that, when I used the <code>API Graph Explorer</code> provided by Facebook Developers, it seems that there's no query string in that sandbox either. How does that work? </p>

  <p><code>Facebook API Graph Explorer</code> DO use query string for access token. Thanks to <a href="https://stackoverflow.com/users/1427878/cbroe">@CBroe</a>'s response.</p>
