Why teams connect Cvent and SQL Server

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

Stacksync mirrors Events, Contacts, Attendees and Registrations, Sessions from Cvent into CDC Change Tables, Stored Procedures, Databases, Schemas in SQL Server 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 SQL Server, 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 Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query
  • 02 Mirror on-premises ERP data held in SQL Server into cloud CRM and support systems
  • 03 Sync Sessions and Speakers into a content database or agenda app so schedule and speaker changes propagate without manual re-entry.
  • 04 Read Budgets and event financials into an ERP or finance database to reconcile planned versus actual event spend.

Common sync patterns

Build audiences from your own data

Segments computed in SQL Server 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 SQL Server 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 SQL Server, so scoring, jobs, and notifications run in the tooling your team already uses.

What you can sync between Cvent and SQL Server

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 SQL Server objects How this pairing syncs
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. Columns Field-level mapping targets with T-SQL types. Events is specific to Cvent and Columns to SQL Server — 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. Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Contacts is specific to Cvent and Primary and Unique Keys to SQL Server — 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. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. Attendees and Registrations is specific to Cvent and CDC Change Tables to SQL Server — 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. Stored Procedures T-SQL logic that can validate or post-process synced rows. Sessions is specific to Cvent and Stored Procedures to SQL Server — 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. Databases Instance-level databases that scope a sync's reads and writes. Speakers is specific to Cvent and Databases to SQL Server — 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. Schemas Namespaces (dbo and custom) used to organize synced tables. Exhibitors is specific to Cvent and Schemas to SQL Server — each maps to any object or custom field on the other side.

How changes propagate between Cvent and SQL Server

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 SQL Server 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 SQL Server as a row-level write, with types converted between the two schemas.

SQL Server Cvent Sub-second propagation

DetectionChanges in SQL Server are captured at the source via change data capture — no polling loop against its API. SQL Server Native Change Data Capture (CDC).

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.
  • SQL Server: No API rate limits; throughput depends on instance resources, licensing tier, and connection limits.

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
