description: >-
  Demostack has a real event surface and advertises it publicly, but publishes
  no AsyncAPI document and no webhook reference. This artifact captures the
  event catalog as Demostack documents it — the webhook product statement on the
  integrations page, plus the per-destination event and field lists in the
  Salesforce, HubSpot and Slack help-center guides. No event names, payload
  schemas, headers, signing scheme, retry policy or delivery guarantees are
  published anywhere, and none are invented here.

    "Push real-time demo events to any CRM, data warehouse, BI tool, or custom
    endpoint. Auto-follow-up when a session ends, flag deals gone cold when demos
    go untouched, and analyze demo activity alongside the rest of your GTM data."
  destinations:
    - any CRM
    - data warehouse
    - BI tool
    - custom HTTP endpoint
  note: >-
    Marked "NEW!" on the integrations page alongside Demostack MCP. Configuration
    is done inside the Demostack application; there is no public documentation of
    the endpoint registration surface, the payload, or the signature.

    note: >-
      Demostack advertises delivery to any custom HTTP endpoint but publishes no
      payload schema for it. An integrator cannot write a receiver from public
      documentation.

gaps:
  - No AsyncAPI document is published on any Demostack host.
  - No named event types (no demo.viewed / session.ended style identifiers).
  - No JSON payload schema or example body for the custom-endpoint destination.
  - No signature header, timestamp, or replay-protection scheme documented.
  - No retry, backoff, or delivery-guarantee statement.
  - No public API for registering or listing webhook endpoints.
