title: Is there a way to know if Vimeo video was watched by current browser user?
body: <p>We are showing several Vimeo videos on a page. We want to show watched videos differently (like you see it on youtube - watched label and video is a bit transparent).</p>
  
  <p>A perfect thing for us would be a JSONP method that you can specify an array of video IDs and it returns a list of flags says which videos were watched by current user.</p>
  
  <p>Better if this can be a non API method (so that this request can be made directly from user's browser with his Vimeo cookies to Vimeo server).</p>
  
  <p>In Vimeo API I could find only how to get all videos watched by me <a href="https://developer.vimeo.com/api/endpoints/me#/watched/videos" rel="nofollow">https://developer.vimeo.com/api/endpoints/me#/watched/videos</a>.</p>
  
  <p><strong>UPD</strong> also posted on Vimeo forums <a href="https://vimeo.com/forums/api/topic:278934" rel="nofollow">https://vimeo.com/forums/api/topic:278934</a></p>
  
  <p><strong>UPD 2</strong> I've checked on youtube: if you are not logged in and you watch a video - it does not appear as "watched" afterwards. So probably this question is not relevant because our users are also mostly not logged into vimeo.</p>
