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). docs: overview: https://developers.cvent.com/docs/webhooks/overview understanding: https://developers.cvent.com/docs/webhooks/understanding-webhooks technical_requirements: https://developers.cvent.com/docs/webhooks/technical-requirements account_setup: https://developers.cvent.com/docs/webhooks/tutorials/account-setup event_setup: https://developers.cvent.com/docs/webhooks/guides/event-setup session_setup: https://developers.cvent.com/docs/webhooks/guides/session-setup manual_sync: https://developers.cvent.com/docs/webhooks/guides/manual-sync meeting_request_form: https://developers.cvent.com/docs/webhooks/guides/mrf reports: https://developers.cvent.com/docs/webhooks/guides/webhooks-reports summary: event_count: 41 groups: 8 events: -
