  title: Graphite Platform
  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.

        Entry point to install the Graphite GitHub App on an organization. The

        push events and calls GitHub's APIs with fine-grained permissions and
        short-lived tokens. Served by GitHub, not by Graphite.
