description: Cvent's published webhook event catalogue. Cvent does NOT publish an AsyncAPI document — no /asyncapi.yaml,
  no event-catalog spec, nothing in the cvent GitHub org — so this records the real event surface as a webhook catalogue
  instead. Each entry has its own documentation page on the developer portal; the message names and grouping are
  Cvent's, read from the published documentation route index. Payload schemas are documented per page and are not
  reproduced here.
asyncapi_published: false
spec_absent_note: No AsyncAPI/CloudEvents/event-catalog artifact is published by Cvent as of 2026-09-07. Nothing
  was generated in its place — an AsyncAPI document authored by us would assert a contract Cvent does not serve.
transport: HTTPS POST to a subscriber-configured URL
subscription:
  style: API-managed + UI
  operations:
  - getContactHooks
  - createContactHook
  - deleteContactHook
  openapi: openapi/cvent-registration-webhooks-api-openapi.yml
  tag: Hooks
  note: The Hooks tag in the REST contract manages contact-hook subscriptions programmatically; event/session/speaker
    webhooks are configured per event in the Cvent UI (see the Event Setup and Session Setup guides).
