    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.

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