Why teams connect Attio and Cvent
Keep the people you sell to and the people you market to in one shared view: Attio and Cvent sync contacts, accounts, and engagement in real time, in both directions.
Attio 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 Custom objects, People, Companies, Users in Attio with Attendees and Registrations, Sessions, Speakers, Exhibitors in Cvent field by field, in real time, and in both directions. You decide which system owns which fields — Attio 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 Keep Attio aligned with a billing system or ERP on customer records and plan status.
- 02 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
- 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
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.
Segments and audiences follow the CRM
Where Cvent builds lists, segments, or ad audiences, membership tracks the fields and stage owned in Attio, so who receives a campaign reflects current pipeline reality instead of a stale export.
Where Cvent generates leads: hand-off without re-keying
New leads or responders captured in Cvent flow into Attio assigned and deduplicated, so nothing sits in a marketing list waiting for someone to export it.
What you can sync between Attio and Cvent
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.
| Attio objects | Cvent objects | How this pairing syncs | |
|---|---|---|---|
| Users Synced with incremental and full sync per the Stacksync docs. | Exhibitors Exhibitor and sponsor records; synced to a CRM or database to track booth, sponsorship, and lead-capture data per event. | Users is specific to Attio and Exhibitors to Cvent — each maps to any object or custom field on the other side. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. | Deals is specific to Attio and Surveys to Cvent — each maps to any object or custom field on the other side. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Budgets Event budget line items; read into a finance database or ERP to reconcile planned versus actual event spend. | Workspaces is specific to Attio and Budgets to Cvent — each maps to any object or custom field on the other side. | |
| Custom objects Workspace-defined objects that behave like standard ones in the API. | 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. | Custom objects is specific to Attio and Events to Cvent — each maps to any object or custom field on the other side. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | 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. | People is specific to Attio and Contacts to Cvent — each maps to any object or custom field on the other side. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | 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. | Companies is specific to Attio and Attendees and Registrations to Cvent — each maps to any object or custom field on the other side. |
How changes propagate between Attio and Cvent
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.
Attio Cvent Sub-second propagation
DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.
DeliveryEach detected change is written to Cvent through its API, with automatic retries and rate-limit backoff.
Cvent Attio 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 Attio through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Attio: Subject to the platform's published API rate limits.
- 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.

FAQ
Attio and Cvent integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Attio and Cvent: authenticate both systems, choose the objects to sync (such as Attio's Users and Deals), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Attio: The data model is user-definable: standard objects like people and companies coexist with custom objects, and attributes can be added to any object, so syncs read the schema at runtime. Cvent: Rate limits are tiered (Free at 1,000 calls/day up to Premium at 500,000 calls/day) and enforced both per-second and as a daily quota that resets at midnight UTC, returning 429 on exhaustion. Stacksync's field mapping accounts for these differences between Attio and Cvent 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 Attio and Cvent records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Attio and Cvent connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Attio–Cvent integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Attio and Cvent. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Attio: Webhooks on record and list-entry events, with polling as a fallback. On Cvent: Per-event webhooks push attendee, registration, session, and speaker changes; list endpoints also expose updatedDate for polling and support on-demand manual sync. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
