Why teams connect Cvent and Postgres Heroku

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

Stacksync mirrors Speakers, Exhibitors, Surveys, Budgets from Cvent into Primary and Unique Keys, JSONB Columns, Sequences, Follower Databases in Postgres Heroku 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 Postgres Heroku, 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 Keep several Heroku app databases aligned with one system of record
  • 02 Reflect billing and subscription records into the app database so product logic reads local rows
  • 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

Build audiences from your own data

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

What you can sync between Cvent and Postgres Heroku

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 Postgres Heroku objects How this pairing syncs
Exhibitors Exhibitor and sponsor records; synced to a CRM or database to track booth, sponsorship, and lead-capture data per event. Materialized Views Precomputed result sets synced outward on refresh. Exhibitors is specific to Cvent and Materialized Views to Postgres Heroku — 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. Schemas Namespaces that scope which tables a sync reads and writes. Surveys is specific to Cvent and Schemas to Postgres Heroku — 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. Primary and Unique Keys Match keys for idempotent upserts from connected systems. Budgets is specific to Cvent and Primary and Unique Keys to Postgres Heroku — 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. JSONB Columns Semi-structured payloads for nested SaaS objects and metadata. Events is specific to Cvent and JSONB Columns to Postgres Heroku — 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. Sequences Generate surrogate keys for rows created by inbound syncs. Contacts is specific to Cvent and Sequences to Postgres Heroku — 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. Follower Databases Heroku-managed read replicas usable as low-impact sync sources. Attendees and Registrations is specific to Cvent and Follower Databases to Postgres Heroku — each maps to any object or custom field on the other side.

How changes propagate between Cvent and Postgres Heroku

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 Postgres Heroku 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 Postgres Heroku as a row-level write, with types converted between the two schemas.

Postgres Heroku Cvent Interval-based propagation

DetectionStacksync polls Postgres Heroku for changes on an incremental schedule, reading only records changed since the previous pass. Trigger-based capture or polling in most configurations.

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.
  • Postgres Heroku: No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan.
