API Youtube, how to get like and dislikes

Question

On a website, i use API Youtube with ZendGdata for retrieve all video of a user and create webpage with the video and his informations.

Now i need to add a system for like or dislikes video on my website, and i need to retrieve the number of likes and dislikes.

(Yes, there are 2 questions here^^)

So, i retrieve for example title with $videoEntry->getVideoTitle();, number of views with $videoEntry->getVideoViewCount(); but how i can retrieve number of likes/dislikes ?

And how i can vote for a video on my website ?

If you take a look at the videos resource in YouTube 3.0 API, among the values included are:

• likeCount
• dislikeCount

Full details here: https://developers.google.com/youtube/v3/docs/videos

If you're using the YouTube 2.0 API, then check out the <yt:rating> tag, which contains the following fields:

• numLikes
• numDislikes

An update to Cormac answer is that youtube will remove this and you can use it for yourself only.

Note: The statistics.dislikeCount property will be made private as of December 13, 2021. This means that the property will only be included in an API response if the API request was authenticated by the video owner. See the revision history for more information.
