Cvent Event Cloud

Cvent Event Cloud Housing API

RegLink APIs allow you to exchange data with Cvent Passkey events and hotel reservation-booking engines. Generally, there are four primary categories of functionality that RegLink APIs support: * **Sync Registrants.** Allow individual registrant information to be sent to Cvent Passkey, streamlining the hotel reservation process for attendees. Attendees can then be directed to Passkey post-registration and reserve a hotel room without re-entering their data again. This is done with the reservation request endpoint. * **Fetch Rooms.** The ability for an external system to fetch Passkey event details and hotel room availability based on various criteria. * **Fetch Reservations.** The ability for an external system to fetch detailed reservation information for individual registrants. This is done with the Reservation endpoint and the Callback system. * **Manage Reservations.** The ability for an external system to create, modify or cancel a registrant's hotel reservation directly or indirectly. If you need authentication credentials or have any questions regarding the RegLink APIs, contact the [Cvent Passkey Integrations Team](https://web.cvent.com/survey/c6a60a30-d981-4ae8-af28-686af0eeb9b7/welcome). * **Passkey.** A software solution allowing your invitees to book room reservations directly with hotels. * **Housing Event.** An Passkey event where invitees will be able to register and book rooms. * **Reservation Request.** Represents a request to book rooms in the housing event. * **RegLink.** A feature that links Passkey events to your registration events, enabling you to sync data between the two events. * **Callback.** [Passkey's callback system](https://developers.cvent.com/docs/passkey/REST/callbacks) allows for a push notification to be sent to your system when a reservation is created, modified or cancelled.
