GAMADV-XTD3 is a free, open source command line tool for Google Workspace Administrators to manage domain and user settings quickly and easily.

GAMADV-XTD3 is built with Python 3; as Python 2 support ends on 2020-01-01, this is the version of Advanced GAM that new/existing users should install.

This page provides simple instructions for downloading, installing and starting to use GAMADV-XTD3.

GAMADV-XTD3 requires paid, or Education/Non-profit, editions of Google Workspace. G Suite Legacy Free Edition has limited API support and not all GAM commands work.

GAMADV-XTD3 is a rewrite/extension of Jay Lee's GAM, without his efforts, this version wouldn't exist.

GAMADV-XTD3 is backwards compatible with GAM, meaning that if your command works with regular GAM, it will also work with GAMADV-XTD3. There may be differences in output, but the syntax is compatible.

Basic GAM documentation is hosted in the GitHub Wiki. Documentation specifically for GAMADV-XTD3 is hosted in the GitHub GAMADV-XTD3 Wiki and in Gam*.txt files.

The GAM mailing list / discussion group is hosted on Google Groups. You can join the list and interact via email, or just post from the web itself.

The official GAMADV-XTD3 source repository is on GitHub in the master branch.

GAMADV-XTD3 is maintained by Ross Scroggs.

To run all commands properly, GAMADV-XTD3 requires three things:

• An API project which identifies your install of GAMADV-XTD3 to Google and keeps track of API quotas.
• Authorization to act as your Google Workspace Administrator in order to perform management functions like add users, modify group settings and membership and pull domain reports.
• A special service account that is authorized to act on behalf of your users in order to modify user-specific settings and data such as Drive files, Calendars and Gmail messages and settings like signatures.

Use these steps if you have never used any version of GAM in your domain. They will create a GAM project and all necessary authentications.
