  summary: Capture, route and deliver webhooks.
  description: >-
    Hookie exposes three HTTP surfaces.


    **Ingest + streaming** is the public plane. A path-form endpoint URL
    authenticates by its own high-entropy slug — there is no key, token or
    cookie — and an `ik_live_…` ingest key authenticates the `/v1/*` routes.
    Whenever the URL names a dataset the payload is stored whole into it;
    project mapping rules are evaluated on exactly one shape, `POST
    /v1/ingest/{ingest_key}` with no dataset segment.


    **The customer portal API** is a separate, token-authed surface for your end
    customers, scoped to one portal and one customer.


    **The admin API** drives the console. It accepts either a browser session or
    an OAuth bearer token from a connected coding agent — the same routes, the
    same validation, the same audit trail. An agent's authority is its user's
    workspace role narrowed to the scopes granted in the console.

        a bearer token is not ambient credentials.
