  title: Graphite Platform Authentication Stacks API
  description: 'Graphite does not publish a standalone public REST API. Graphite is built on top of GitHub: it installs as a GitHub App (graphite-app) that consumes GitHub webhooks and calls GitHub''s APIs with short-lived tokens, and it is driven by the gt CLI which authenticates with a Graphite auth token. This OpenAPI models the real, observable surface area as logical operations: the GitHub App install entry point and the documented gt CLI stacked-PR workflow operations. Endpoint paths for CLI operations are illustrative of the platform actions the CLI performs and are not a documented public HTTP contract.'
