# Google Tag Manager

Google Tag Manager is a tag management system that lets teams deploy and update measurement codes and related code fragments — collectively known as tags — on a website, mobile app, or server-side container without editing site code on every change. The Tag Manager API v2 exposes that configuration programmatically: accounts, containers, workspaces, tags, triggers, variables, container versions, and user permissions, across web, iOS, Android, AMP, and server-side usage contexts. Changes are staged in a workspace, frozen into an immutable container version, and then published to live traffic, with fingerprint-based optimistic concurrency guarding every write. Access is OAuth 2.0 only, with seven granular scopes separating read, edit, publish, and user-management rights.
