Ruby Code Samples

  • This webpage provides code samples for the YouTube Data API using the Google APIs Client Library for Ruby, downloadable from the ruby folder in the YouTube APIs code sample repository on GitHub.

  • The samples include functionality for adding a channel subscription, which is done by calling the subscriptions.insert method.

  • OAuth 2.0 authorization is demonstrated through a code sample that checks for a local file with credentials, and if not present, opens a browser to get them and save them for future use.

  • Another sample code allows users to retrieve videos that have been uploaded to their channel by using the playlistItems.list method and the channels.list method.

  • Users can use a code sample that utilizes the search.list method to search YouTube for specific keywords, and it will retrieve videos, channels, and playlists related to the searched term.

  • A sample is available that shows how to upload a video to a YouTube channel using the videos.insert method.

The following code samples, which use the Google APIs Client Library for Ruby, are available for the YouTube Data API. You can download these code samples from the ruby folder of the YouTube APIs code sample repository on GitHub.
