title: Is it possible (and how) to get comments left on youtube on any account/channel?
body: <p>I'm trying to use this code <code>https://www.googleapis.com/youtube/v3/comments?part=snippet&amp;id=zwGBTcIHN0U&amp;key={YOUR_API_KEY}</code> (clearly with a proper key) to get comments left on a random channel, random video but I get an empty list as result:</p>
  
  <pre><code>{
   "kind": "youtube#commentListResponse",
   "etag": "\"tbWC5XrSXxe1WOAx6MK9z4hHSU8/pGLBhpjR05yQoJV31WoAx2PEFVw\"",
   "items": []
  }
  </code></pre>
  
  <p>I can't find proper documentation beside the official one: <a href="https://developers.google.com/youtube/v3/docs/comments/list#try-it" rel="nofollow">https://developers.google.com/youtube/v3/docs/comments/list#try-it</a></p>
  
  <p>Any help?</p>
