Finally, this document defines the parameters used in You Tube Data API requests as well as the XML tags returned in an API response.For Java, PHP and Python developers, the XML tags may correspond directly to a property of a Video Entry, Profile Entry or other type of object.The You Tube Data API retrieves search results from a specially optimized search index.
Please note that there may be delays between the time that a video is uploaded or updated and the time the new information is included in video feeds.
The following list provides expected data latencies for various API functions: The You Tube Data API offers different views, or projections, of the data available in the API.
A projection changes the structure of a feed but does not alter the content of a feed.
Note: The You Tube Data API (v2) has been officially deprecated as of March 4, 2014.
Please refer to our deprecation policy for more information.
Please use the You Tube Data API (v3) for new integrations and migrate applications still using the v2 API to the v3 API as well.This document is intended for programmers who are writing client applications that interact with You Tube.The document supplements the information in the developer's guide protocol as well as the language-specific guides for Java, PHP and Python developers.This document lists the different types of feeds that you can retrieve using the You Tube Data API.It also provides diagrams that explain how to navigate between different feeds – for example, the diagrams show that a user's playlists feed contains URLs that reference individual playlists and data such as a user's profile.The diagrams also indicate how you would navigate from one feed to another.
