Why teams connect Cvent and MongoDB

Give your team Cvent's contacts, campaigns, and engagement in MongoDB: query them with SQL, push audiences built from your own data back to Cvent, and skip the marketing API.

Cvent holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in MongoDB, hard to get into campaigns without manual exports.

Stacksync mirrors Budgets, Events, Contacts, Attendees and Registrations from Cvent into Databases, Collections, Documents, Embedded documents and arrays in MongoDB field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in MongoDB, from usage, orders, or account status, sync back into Cvent to drive campaigns and ads, with Cvent kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Keep a MongoDB-backed product catalog aligned with an ERP's item master in both directions.
  • 02 Consolidate documents from multiple clusters or tenants into a single warehouse-facing store.
  • 03 Write Attendees and Registrations into Cvent from external marketing signup flows, then read attendance status back into a warehouse.
  • 04 Sync Sessions and Speakers into a content database or agenda app so schedule and speaker changes propagate without manual re-entry.

Common sync patterns

React to marketing changes as row changes

A new lead, form fill, or list change in Cvent arrives as a row change in MongoDB, so scoring, jobs, and notifications run in the tooling your team already uses.

Keep contact attributes consistent

Lifecycle stage, subscription status, or plan maintained on either side stays current on the other, ending exports and dual data entry.

Query Cvent like a database

Contacts, leads, audiences, and campaign metrics from Cvent live in MongoDB as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.

What you can sync between Cvent and MongoDB

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Cvent objects MongoDB objects How this pairing syncs
Contacts Account-wide people database spanning every event; synced two-way with a CRM or warehouse as the shared audience source of truth via the Create Contacts endpoint. Databases Logical groupings of collections that scope a sync connection. Contacts is specific to Cvent and Databases to MongoDB — each maps to any object or custom field on the other side.
Attendees and Registrations Per-event registrants; written in from CRM or marketing signup flows via POST /ea/attendees and read back out to a warehouse for attendance and registration-status reporting. Collections The table-like sync unit; each collection maps to a table or object in the paired system. Attendees and Registrations is specific to Cvent and Collections to MongoDB — each maps to any object or custom field on the other side.
Sessions Agenda items within an event; listed or created through the API and synced so session-level attendance feeds reporting tables. Documents BSON records created, updated, and deleted during syncs, keyed by _id. Sessions is specific to Cvent and Documents to MongoDB — each maps to any object or custom field on the other side.
Speakers Speaker records tied to an event; synced two-way with a speaker database or CMS, with an updatedDate on each record for incremental pulls. Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. Speakers is specific to Cvent and Embedded documents and arrays to MongoDB — each maps to any object or custom field on the other side.
Exhibitors Exhibitor and sponsor records; synced to a CRM or database to track booth, sponsorship, and lead-capture data per event. Indexes Keep lookups by sync key fast on large collections. Exhibitors is specific to Cvent and Indexes to MongoDB — each maps to any object or custom field on the other side.
Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. Views Read-only aggregation-defined sources for filtered sync datasets. Surveys is specific to Cvent and Views to MongoDB — each maps to any object or custom field on the other side.

How changes propagate between Cvent and MongoDB

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Cvent MongoDB Sub-second propagation

DetectionCvent notifies Stacksync of record changes through webhook events. Per-event webhooks push attendee, registration, session, and speaker changes.

DeliveryEach detected change is applied to MongoDB as a row-level write, with types converted between the two schemas.

MongoDB Cvent Sub-second propagation

DetectionChanges in MongoDB are captured at the source via change data capture — no polling loop against its API. MongoDB oplog and change streams (requires the database to run as a replica set — even single-node).

DeliveryEach detected change is written to Cvent through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Cvent: Responses carry X-RateLimit-Limit/Remaining/Reset headers; a 429 signals either the per-second limit (retry with exponential backoff from ~2s) or the daily quota (up to 500,000 calls/day on the Premium tier, 1,000/day on Free) exhausted until midnight UTC.

How the Cvent and MongoDB connectors work

Cvent

Integration surface
Cvent REST API (JSON over HTTPS at api-platform.cvent.com/ea, paginated list endpoints)
Authentication
OAuth 2.0 client-credentials flow: a client ID and secret are Basic-auth exchanged for a 60-minute bearer token at api-platform.cvent.com/ea/oauth2/token; legacy API-key and SOAP/CSN auth are deprecated
Change detection
Per-event webhooks push attendee, registration, session, and speaker changes; list endpoints also expose updatedDate for polling and support on-demand manual sync
