Page Summary
-
This content provides a code sample utilizing the Google APIs Client Library for .NET to interact with the YouTube Content ID API.
-
The code demonstrates how to retrieve a list of channels that are managed by a specific content owner through the
channels.listmethod of the YouTube Data API. -
The sample requires OAuth 2.0 authentication, using
NativeApplicationClientto handle credentials and authorization, with specific scopes includingYoutubeReadonlyandYoutubepartner. -
The code fetches and displays the titles and IDs of up to 50 channels per page, with support for pagination using the
nextPageTokento retrieve additional results.
The following code samples, which use the Google APIs Client Library for .NET , are available for the YouTube Content ID API .
