YouTube has announced new policy which will take off in the coming month.
In an email send to all YouTubers, public dislike on video will be made private starting from 13th of December 2021.
However, the company give option for anyone who want to make it public dislike public on it channels to apply in a form accompanying the email.
The email read:
Dear YouTube API developer,
We would like to inform you of upcoming changes to YouTube that will impact the data available via the Data API starting December 13, 2021.
On November 10, YouTube will be making the public dislike count private. Users will still be able to dislike videos, and creators will still have access to the dislike counts for their own videos in YouTube Studio. Learn more about this change in our blog post.
To make the dislike count private across the platform, we also will be removing public access to the dislike count data via our API.
Here are details on how this will and will not affect the API:
The dislike_count field within the statistics part of the video resource will be omitted on calls to the video.list endpoint except in cases in which the request is being authenticated as a user (such as the creator or the agent user) who owns the video that is being requested.
The videos.rate endpoint will be unaffected.
Developers who do not display dislike counts publicly and still need the dislike count for their API client can apply to be put on an allow list for an exemption.
If you would like to apply for an exemption, you must complete this application form. Otherwise, your access to public dislike count data via the Data API will end on December 13, 2021.
Thank you for being a YouTube API developer.
The YouTube API Services team
