Why teams connect Cvent and Seismic

Keep the people you sell to and the people you market to in one shared view: Seismic and Cvent sync contacts, accounts, and engagement in real time, in both directions.

Seismic owns the customer relationship and the pipeline; Cvent runs the campaigns, audiences, and outreach that fill it. The two overlap on the same people and companies — a lead in one system is a subscriber, a segment member, an event registrant, or an ad audience in the other. When that overlap is bridged by CSV exports or a nightly job, sales works from lists that no longer match reality and marketing keeps targeting people whose status has already moved on.

Stacksync syncs Reporting Activities, Library Content, Content Versions, Users in Seismic with Sessions, Speakers, Exhibitors, Surveys in Cvent field by field, in real time, and in both directions. You decide which system owns which fields — Seismic can own account and opportunity status while Cvent owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.
  • 02 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
  • 03 Read Budgets and event financials into an ERP or finance database to reconcile planned versus actual event spend.
  • 04 Write Attendees and Registrations into Cvent from external marketing signup flows, then read attendance status back into a warehouse.

Common sync patterns

New and updated people stay in step

When a contact or lead is created or edited in either system, the matching record appears or updates in the other, so campaigns reach real people and reps see who is already being marketed to.

Where Cvent captures engagement: activity lands on the record

Opens, clicks, form fills, event attendance, or ad responses recorded in Cvent post back to the contact or account in Seismic, so reps see interest before they reach out.

Lead and lifecycle status agree

Status, stage, or score set in one system updates the matching record in the other, so a lead marketing is still nurturing is not worked as sales-ready, and a closed account stops receiving prospecting.

What you can sync between Cvent and Seismic

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 Seismic 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. Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Speakers is specific to Cvent and Users to Seismic — 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. User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Exhibitors is specific to Cvent and User Groups to Seismic — 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. Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. Surveys is specific to Cvent and Teamsites to Seismic — 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. LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. Budgets is specific to Cvent and LiveSend Links to Seismic — 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. Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. Events is specific to Cvent and Digital Sales Rooms to Seismic — 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. Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. Contacts is specific to Cvent and Reporting Activities to Seismic — each maps to any object or custom field on the other side.

How changes propagate between Cvent and Seismic

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 Seismic 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 Seismic through its API, with automatic retries and rate-limit backoff.

Seismic Cvent Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

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.
  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.
