  version: v2
  description: 'Event Cloud surface of the Cvent Platform REST API — events,

    contacts, registrations, attendees, sessions, exhibitors, surveys,

    Attendee Hub, and webhook resources. Provides programmatic access to events, contacts,

    registrations, attendees, sessions, exhibitors, surveys, webhooks, and

    related Event Cloud resources, authenticated via OAuth 2.0 client

    credentials. Endpoint host varies by region — US accounts use

    api-platform.cvent.com and EMEA accounts use api-platform-eur.cvent.com.


    Best-effort spec derived from Cvent developer portal documentation

    (overview, quickstart, Registration Guide, Managing Events Guide).

    Refer to https://developers.cvent.com/docs/rest-api/overview for the

    authoritative reference and downloadable OpenAPI.
