title: Search video with vimeo Api using javascript
body: <p>I want to use the new vimeo api to fetch videos based on a query, but I getting a 401 Authorization Required with this message "error": "A valid user token must be passed."</p>
  
  <p>I'm using this code :</p>
  
  <pre><code>var urlX = 'https://api.vimeo.com/videos?query=elvis&amp;client_id='+VIMEO_API_KEY;
  
  $.getJSON(urlX, function(data){
  console.log(data);
  });
  </code></pre>
  
  <p>So obviously I have an authentication problem. 
  As client_id I'm using my "Client Identifier" from my app created in Vimeo's dashboard. 
  The error I keep getting mention "user token", do I have to generate one via Vimeo's dashboard or via php ?
  I'm a bit lost here.</p>
