title: dropbox api authentication SSL error
body: <p>I try to be authenticated using <a href="https://github.com/kunalvarma05/dropbox-php-sdk" rel="nofollow noreferrer">Dropbox-php-sdk</a>. Therefore i use localhost development environment without ssl. Is that possible or not as i get the following error:</p>
  
  <pre><code>$callbackUrl = "http://localhost/dropboxphp/finish.php";
  
  $accessToken = $authHelper-&gt;getAccessToken($code, $state, $callbackUrl);
  echo $accessToken-&gt;getToken();
  </code></pre>
