Developer APIs

YouTube offers access to the YouTube video repository and community features via a GoogleData ("GData") API.


Legacy API Information

The older API is officially deprecated. If you're developing new projects on the YouTube platform, you should use the new API to ensure support.

See the migration guide for more information about updating websites or applications based on the legacy API.
