title: Get Vimeo thumbnails for private videos
body: <p>I have a list of Vimeo private video urls (<code>https://player.vimeo.com/video/1234567890</code>), which I'd like to display as thumbnails on my page.
  I can't find a working way to do it. </p>
  
  <p>Any solutions based on <code>http://vimeo.com/api/v2/video/{id}</code> are long dead. </p>
  
  <p>And something like this <code>https://i.vimeocdn.com/video/1234567890.jpg</code> would return the wrong image.</p>
  
  <p>Is there a way to get an image thumbnail url based on video id without authorization ?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>In my case, I manged to get the <code>thumbnail_url</code> by querying</p>
  
  <p><code>GET https://vimeo.com/api/oembed.json?url=https://player.vimeo.com/video/{id}</code></p>
