Why teams connect Cvent and Google Cloud Spanner

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

Stacksync mirrors Surveys, Budgets, Events, Contacts from Cvent into Interleaved tables, Secondary indexes, Change streams, Views in Google Cloud Spanner 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 Google Cloud Spanner, 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 Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • 02 Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.
  • 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 Google Cloud Spanner 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 Google Cloud Spanner 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 Google Cloud Spanner, so scoring, jobs, and notifications run in the tooling your team already uses.

What you can sync between Cvent and Google Cloud Spanner

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 Google Cloud Spanner objects How this pairing syncs
Budgets Event budget line items; read into a finance database or ERP to reconcile planned versus actual event spend. Secondary indexes Used to make incremental read queries efficient on non-key columns. Budgets is specific to Cvent and Secondary indexes to Google Cloud Spanner — 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. Change streams Capture inserts, updates, and deletes for log-style change data capture. Events is specific to Cvent and Change streams to Google Cloud Spanner — 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. Views Read-only projections useful for shaping data before it leaves Spanner. Contacts is specific to Cvent and Views to Google Cloud Spanner — 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. Databases Top-level containers that scope schema and sync configuration. Attendees and Registrations is specific to Cvent and Databases to Google Cloud Spanner — 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. Tables Relational tables mapped one-to-one to sync targets. Sessions is specific to Cvent and Tables to Google Cloud Spanner — 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. Rows The unit of read and write in each sync cycle, keyed by primary key. Speakers is specific to Cvent and Rows to Google Cloud Spanner — each maps to any object or custom field on the other side.

How changes propagate between Cvent and Google Cloud Spanner

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 Google Cloud Spanner 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 Google Cloud Spanner as a row-level write, with types converted between the two schemas.

Google Cloud Spanner Cvent Sub-second propagation

DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.

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.
  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
