body: <p>How to create button for owner YouTube account for opening streaming live video?</p>
  
  <p>In YouTube, on Creator Studio in "Live Streaming" there is list of events. Each events with status "Live Now" has button "Resume Hangout On Air". This button has property named <code>data-token</code> which allows to open Hangouts.</p>
  
  <p>The link looks like: <code>https://hangouts.google.com/hangouts/_/ytl/[data-token]</code></p>
  
  <p>The question is, how I can get <code>data-token</code> from YouTube API or maybe there are other ways? </p>
