Why teams connect Cvent and OpenSearch

Give your team Cvent's contacts, campaigns, and engagement in OpenSearch: 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 OpenSearch, hard to get into campaigns without manual exports.

Stacksync mirrors Sessions, Speakers, Exhibitors, Surveys from Cvent into Data streams, Snapshots, Indexes, Documents in OpenSearch 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 OpenSearch, 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 Index support tickets and activity logs from SaaS tools for operational dashboards.
  • 02 Backfill or rebuild indexes from a database after mapping changes without hand-written ETL.
  • 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

Build audiences from your own data

Segments computed in OpenSearch from product usage, orders, or account status sync into Cvent as lists or audiences, so campaigns and ads target the people your data says they should.

Engagement and results next to the customer

Opens, clicks, sends, RSVPs, or ad activity from Cvent land in OpenSearch beside the matching customer record, ready for reporting and revenue attribution.

React to marketing changes as row changes

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

What you can sync between Cvent and OpenSearch

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 OpenSearch objects How this pairing syncs
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. Indexes The core container; synced records land in indexes with defined mappings Speakers is specific to Cvent and Indexes to OpenSearch — 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. Documents JSON records written via the index and bulk APIs and read via search queries Exhibitors is specific to Cvent and Documents to OpenSearch — 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. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills Surveys is specific to Cvent and Index aliases to OpenSearch — each maps to any object or custom field on the other side.
Budgets Event budget line items; read into a finance database or ERP to reconcile planned versus actual event spend. Index templates Mapping and settings presets applied to new indexes a sync creates Budgets is specific to Cvent and Index templates to OpenSearch — each maps to any object or custom field on the other side.
Events Top-level event containers created and updated through the Events endpoints; read out for reporting and written to provision events from an external system. Ingest pipelines Server-side processors that transform documents as they are written Events is specific to Cvent and Ingest pipelines to OpenSearch — each maps to any object or custom field on the other side.
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. Data streams Append-oriented time-series storage for logs and events pushed from source systems Contacts is specific to Cvent and Data streams to OpenSearch — each maps to any object or custom field on the other side.

How changes propagate between Cvent and OpenSearch

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 OpenSearch 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 written to OpenSearch through its API, with automatic retries and rate-limit backoff.

OpenSearch Cvent Interval-based propagation

DetectionStacksync polls OpenSearch for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.

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.
  • OpenSearch: Throughput bounded by cluster sizing rather than fixed API quotas.
