Cvent Registration Attendees API covers event registrations and attendees. It is part of Cvent Registration, the event registration product in the Cvent Event Cloud. That product handles online registration websites, attendee data capture, payment processing, group registration, custom field collection and badge or on-site check-in workflows. Teams that build integrations for events, conferences and ticketing would use this API to work with registration and attendee data programmatically. It runs on the unified Cvent Platform REST API at api-platform.cvent.com and uses OAuth 2.0 client credentials. The Cvent developer portal has a dedicated Registration Guide, and Cvent Webhooks deliver real-time registration changes.
