Cvent REST APIs
★ Only Publicly Available OpenAPI DocumentProductivityCalendar Schedulingoauth2427 EndpointsREST
For Agents
Manage Cvent events end to end - registrations, attendees, sessions, exhibitors, surveys, badges, and webhooks - via 427 REST endpoints behind OAuth2.
Use for: I need to register an attendee for a Cvent event, List all sessions running on day two of the user conference, Schedule an appointment between two attendees during the event, Find exhibitors who have not completed their booth profile
Not supported: Does not handle ticket discovery on third-party marketplaces, generic CRM contact storage, or payment processing networks - use for managing your own events on the Cvent platform only.
Jentic publishes the only available OpenAPI specification for Cvent REST APIs, keeping it validated and agent-ready. Cvent is an enterprise event-management platform covering in-person, virtual, and hybrid events, exhibitors, attendee journeys, surveys, travel, and webcasts. The REST API exposes 427 endpoints across attendees, sessions, registrations, exhibitors, badges, surveys, housing, travel, payments, and webhooks. It supports OAuth2 client-credentials and authorization-code flows and is hosted in both North American and European data centres.
Install Jentic One Beta
Connect the Cvent REST APIs to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Cvent REST APIs, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Cvent REST APIs.
Register and update attendees against an event via the /attendees endpoints
Manage event sessions, speakers, and seating using /sessions and related resources
Schedule appointments and check availability through /appointment-events and /appointment-availability-times
Run surveys and collect responses via the /surveys endpoint group
Coordinate exhibitor profiles, content, and team rosters under /exhibitor* endpoints
Subscribe to event lifecycle webhooks via /hooks and trigger badge prints via /badge-print-job
Use Cases
Patterns agents use Cvent REST APIs for, with concrete tasks.
★ Event registration automation
Automate attendee registration from a marketing form or CRM into a Cvent event. Code creates or updates the attendee record via /attendees, attaches custom field values, and confirms registration status. Cvent handles confirmations, badges, and downstream housing or travel coordination.
Create an attendee with email jane@example.com on event 12345 and confirm the registration status field is 'Registered'.
On-site session and appointment management
Run an on-site portal that lets attendees browse sessions, book 1:1 appointments with exhibitors, and check capacity in real time. The /appointment-events and /sessions endpoints expose availability, allow bookings, and surface speakers, so a custom mobile app or kiosk can drive the floor experience.
List available 1:1 appointment slots on event 7890 between 14:00 and 16:00 and book the first slot for attendee 56789.
Post-event survey and reporting
Send a survey after the event and pipe responses into a BI tool. The /surveys endpoints expose responses, and /attendee-insights surfaces engagement signals so revenue and marketing operations can score sessions and update lead records in the CRM.
Pull all completed responses for survey 42 on event 12345 and write them to the analytics warehouse.
Exhibitor and lead capture coordination
Coordinate exhibitor onboarding, booth content, and lead retrieval across a multi-day event. The /exhibitor, /exhibitor-content, and /leads endpoints let an exhibitor portal manage profiles, accept lead scans, and sync the captured leads back into Salesforce or HubSpot.
List leads captured by exhibitor 123 on event 7890 in the last 24 hours and push them into the CRM.
AI agent event assistant via Jentic
Expose Cvent operations to an autonomous agent so it can answer attendee questions, register guests, or pull session schedules during an event. The agent searches Jentic for 'register an attendee for an event', loads the schema, and executes - the OAuth tokens stay in the Jentic vault.
Through Jentic, register attendee Jane Doe (jane@example.com) on event 12345 and reply with the confirmation number.

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Cvent OAuth2 client credentials live in the Jentic vault. Jentic mints short-lived bearer tokens at execution time so the agent never sees the client secret and tokens never persist in prompt context.
Intent-based discovery
Agents search by intent (e.g. 'register an attendee for an event') and Jentic returns the matching Cvent operation with its OAuth scopes and parameter schema, so the agent doesn't have to navigate 427 endpoints.
Time to first call
Direct Cvent integration: 1-2 weeks for OAuth2 client setup, token refresh, and endpoint mapping. Through Jentic: under a day to wire the first end-to-end agent flow.

FAQs
Specific to using Cvent REST APIs through Jentic.
Why is there no official OpenAPI spec for Cvent?
Cvent does not publish a single OpenAPI specification covering its full REST surface. Jentic generates and maintains this spec so that AI agents and developers can call Cvent via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the Cvent REST API use?
OAuth2 with both client-credentials and authorization-code flows. You exchange your application's client ID and secret at the OAuth2 token endpoint to receive a bearer token valid for one hour, which is then sent in the Authorization header on subsequent calls.
Can I register an attendee for an event through the API?
Yes. The /attendees endpoint group lets you create, update, and look up attendee records on a specific event, including custom field values and registration status.
Does Cvent support webhooks for event lifecycle changes?
Yes. The /hooks endpoints let you subscribe to event lifecycle notifications - registrations, session updates, and other state changes - so downstream systems can react without polling.
What are the rate limits for the Cvent REST API?
Cvent enforces tiered limits: Free at 1,000 calls/day and 2 calls/sec, Standard at 15,000 calls/day and 10 calls/sec, Premium at 500,000 calls/day and 25 calls/sec. Daily quotas reset at midnight GMT and 429 responses indicate you have hit a limit.
How do I register an attendee through Jentic?
Run pip install jentic, search for 'register an attendee for an event', load the /attendees POST schema, and execute with the event ID and attendee fields. Jentic handles the OAuth2 token exchange so your code never sees the client secret.
