Since its initial launch in 2007, the YouTube Data API has become one of Google’s most popular APIs by request volume, thanks to the awesome apps from developers like you. To help you make better integrated video experiences, you can now use the YouTube API version 3.0. The new API is easy to use thanks to rich client library support, improved tooling, reference documentation and integration with Google’s common API infrastructure. Version 3.0 only returns what you ask for and uses JSON rather than XML encoding for greater efficiency. The API introduces new core functionality including Freebase integration via topics, and universal search. If you develop social media management apps, you’ll love channel bulletin post and full subscriber list management, also new in this release. Version 3.0 of the API constitutes the API's biggest overhaul to date and we’re eager for you to try it today!
New functionality: Topics, universal search, and audience engagement support
Have you ever tried to search for YouTube videos only to find out that keyword search can produce ambiguous results? With the new Topics API, thanks to the power of Freebase, you can find exactly what you’re looking for by specifying Freebase topic IDs rather than search keywords.
For example, if you’re reading this post from outside of the US and you would like to search for content related to football, /m/02vx4 is probably the topic ID you're after. The API's universal search feature lets you retrieve channels, playlists and videos matching the topic with just one request like this one. Find out more in our Topics API Guide.
Version 3.0 introduces better tools to engage and interact with your YouTube audience. Social media management apps can now help content creators communicate with their channel subscribers using bulletin posts.
If you would like to learn more about the YouTube API version 3.0, read the full post on The YouTube API Blog. The post covers efficiency improvements, features several companies already using version 3.0 and contains useful links to source code examples and documentation.
