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

GAMADV-XTD3 is built with Python 3.

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

GAMADV-XTD3 requires G Suite for Business, Education, Non Profit, Partner or Government Edition. Google Apps 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.


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

Mailing List / Discussion group

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.

Source Repository

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 G Suite 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.
