Graph API Explorer > Get User Access Token > always gives "Token Expired"; What's wrong?! & How to overcome?
<p>A little <strong>Update*</strong> at the end of the question.</p>

<hr>

<p>It is the very first time I try to use Facebook API. I am following this <a href="https://www.youtube.com/watch?v=GwbO_PdwK_4" rel="nofollow noreferrer">video tutorial</a>. I logged in correctly to Facebook and after that I registered to <a href="https://developers.facebook.com/" rel="nofollow noreferrer">developers.facebook.com</a> I followed these steps:</p>

<ul>
<li>Click <strong>Tools &amp; Support</strong>  </li>
<li>Under <strong>Tools</strong> click <strong>Graph API Explorer</strong></li>
<li>Select <strong>Graph API Explorer</strong></li>
<li>Select <strong>Get User Access Token</strong></li>
<li>Select All the options from both <strong>User Data Permissions</strong> &amp; <strong>Extended Permissions</strong> </li>
<li>Click <strong>Get Access Token</strong> - After that I click three <strong>OKay</strong>'s with default settings.</li>
</ul>

<p>I got what is shown in this image:<br>
I clicked on <em>refresh</em> many times, and I also tried <kbd>ALT</kbd>+<kbd>T</kbd>, but it always gives <strong>Token Expired</strong>.</p>

<p><strong>Update*</strong></p>

<p>I copied the access token despite the message <strong>"Token Expired"</strong> is still exist, and I continue following the tutorial, and it works OK!!</p>

<p>I am happy that it works now. But what is the wrong that yields this alert message?!</p>
