I would like to work with the Google Admin SDK and get information about our domain's email settings per user. I refer to Developer's Guide | Email Settings API
I am comfortable approaching the problem in Java, Python, and C# and all three languages have examples included in the documentation.
Where can I get all these libraries shown in the documentation?
C#
using Google.GData.Apps;
using Google.GData.Apps.GoogleMailSettings;
using Google.GData.Client;
using Google.GData.Extensions;
Java
import sample.appsforyourdomain.gmailsettings.GmailSettingsService;
Python
import gdata.apps.emailsettings.client
