In an effort to maximize visibility for domain admins, we recently started logging admin actions related to Google Apps Marketplace (GAM) apps in Admin console. Admins can now view logs for whenever they install/uninstall a GAM app and when they grant/revoke data grants for an app. Admins can view this data in the Reporting section of Admin console.
Rapid release and Scheduled release
