How to retrieve a YouTube video's tags with YouTube v3 API?

I want to retrieve the tags for a specific YouTube video using v3 of the YouTube API. I'm able to retrieve a video with this request to the search endpoint, https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=1&q=cats&type=video&key={YOUR_API_KEY}. Now I hit the video endpoint trying to get the tags for the video from the above query. https://www.googleapis.com/youtube/v3/videos?id=IytNBm8WA1c&part=snippet&key={YOUR_API_KEY} Response, ``` { "kind": "youtube#videoListResponse", "etag": "\"PMn2rAVTRiZHkX45qiqfcLZoTXM/rYBuk4KeZFmSMoiSuaXfy6-Pm28\"", "items": [ { "id": "IytNBm8WA1c", "kind": "youtube#video", "etag": "\"PMn2rAVTRiZHkX45qiqfcLZoTXM/_6K6Qz8rLYf0d5gUnucV1LwbwU4\"", "snippet": { "publishedAt": "2007-07-09T14:02:03.000Z", "channelId": "UCFMV3DqmnaRc4oNGvi-3OvQ", "title": "Funny Cats", "description": "it's soo funny :D\r\n\r\naudio content is licensed by UMG\r\n\r\nSong 1: Gioachino Rossini - The Thieving Magpie 0:00 - 1:37\r\nSong 2: The Presidents of the United States of America - Kitty 1:38 - 2:47\r\nSong 3: The Nutcracker 2:48 - 3:51\r\nSong 4: Smash Mouth - All Star 3:51 - 7:06\r\nSong 5: The Wiseguys - Ooh La La 7:07 - 7:43\r\n\r\nPS: i will ignore messages with the subject\r\n\"Business Proposal Regarding Your YouTube Videos\"", "thumbnails": { "default": { "url": "https://i.ytimg.com/vi/IytNBm8WA1c/default.jpg" }, "medium": { "url": "https://i.ytimg.com/vi/IytNBm8WA1c/mqdefault.jpg" }, "high": { "url": "https://i.ytimg.com/vi/IytNBm8WA1c/hqdefault.jpg" } }, "channelTitle": "nguoap", "categoryId": "15" } } ] } ``` API Explorer for this request - https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.videos.list?id=IytNBm8WA1c&part=snippet&_h=3& Even if I authorize this request I get the same results. Although, if the account being authorized owns the video it returns the tags. How can I get the tags for the videos I own without asking the end-user to authorize their accounts? This implementation is client side with JS. UPDATE: GData Issue Link: https://code.google.com/p/gdata-issues/issues/detail?id=4513
