description: >-
  Cvent publishes a full webhook catalogue on its developer portal — 40 documented message types
  across eight subject areas, each with its own reference page — plus a REST surface for managing
  subscriptions (the Hooks tag, /hooks and /contacts/hooks). It does NOT publish an AsyncAPI
  description of any of it, so the event surface is documented for humans and unavailable to
  machines except by reading the OpenAPI callback declaration.

  callback_declared: true
  callback_note: >-
    POST /contacts/hooks is the one operation in the whole 458-operation spec that declares an
    OpenAPI `callbacks` object, so the contact-hook payload shape IS machine-readable. The other
    39 message types are documented only in prose.

    - scheme: CallbackApiKeyAuth
      type: apiKey
      in: header
      name: Authorization
      description: >-
        Tells Cvent to use API key auth when invoking YOUR callback endpoint. Cannot be used to call
        Cvent.
    - scheme: CallbackBasicAuth
      type: http
      scheme_name: basic
      description: Tells Cvent to use HTTP Basic when invoking your callback endpoint.

  groups: 8
  asyncapi_document: false
  machine_readable_payloads: 1
  note: >-
    40 documented message types, exactly one of which has a machine-readable payload contract. An
    AsyncAPI document over this catalogue is the single largest missing artifact on Cvent's event
    surface.
