Why teams connect Cvent and Nutshell
Keep the people you sell to and the people you market to in one shared view: Nutshell and Cvent sync contacts, accounts, and engagement in real time, in both directions.
Nutshell 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 People, Companies, Activities, Tasks in Nutshell with Events, Contacts, Attendees and Registrations, Sessions in Cvent field by field, in real time, and in both directions. You decide which system owns which fields — Nutshell 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 Sync Nutshell leads into a warehouse or Postgres so small B2B teams can report on pipeline without exports.
- 02 Push closed-won leads to accounting software to trigger invoicing automatically.
- 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
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 Nutshell, 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 Nutshell
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 | Nutshell objects | How this pairing syncs | |
|---|---|---|---|
| Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. | Leads Nutshell's deal object; synced as the pipeline record linked to people and companies | Surveys is specific to Cvent and Leads to Nutshell — 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. | People Individual contacts, kept consistent with marketing and outreach tools | Budgets is specific to Cvent and People to Nutshell — 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. | Companies Account records that group people and leads for account-level syncs | Events is specific to Cvent and Companies to Nutshell — 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. | Activities Logged calls, meetings, and emails used for engagement reporting | Contacts is specific to Cvent and Activities to Nutshell — 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. | Tasks Rep to-dos mirrored into external work-management or reporting systems | Attendees and Registrations is specific to Cvent and Tasks to Nutshell — 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. | Notes Free-text history attached to leads and contacts, replicated for a full timeline | Sessions is specific to Cvent and Notes to Nutshell — each maps to any object or custom field on the other side. |
How changes propagate between Cvent and Nutshell
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 Nutshell 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 Nutshell through its API, with automatic retries and rate-limit backoff.
Nutshell Cvent Sub-second propagation
DetectionNutshell notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling as fallback.
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.
- Nutshell: Subject to the platform's API rate limits.

FAQ
Cvent and Nutshell integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Cvent and Nutshell: authenticate both systems, choose the objects to sync (such as Cvent's Surveys and Budgets), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Nutshell: The deal object is called a Lead in Nutshell, and it links to separate People and Company records rather than replacing them. Cvent: The current unified REST API supersedes the legacy SOAP-based Cvent API and CSN API; API-key authentication is deprecated in favor of OAuth 2.0. Stacksync's field mapping accounts for these differences between Cvent and Nutshell without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Cvent and Nutshell records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Cvent and Nutshell connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Cvent–Nutshell integration in-house.
