Why teams connect Postgres Heroku and Seismic
Treat Seismic like part of your database: its records live in Postgres Heroku as real tables, and writes in either place sync to the other in seconds.
Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in Postgres Heroku, where it can be queried and joined like everything else.
Stacksync mirrors Content Versions, Users, User Groups, Teamsites from Seismic into Materialized Views, Schemas, Primary and Unique Keys, JSONB Columns in Postgres Heroku with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Seismic with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.
Common use cases
- 01 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
- 02 Extract content-interaction and LiveSend engagement from the Reporting API v2 into a warehouse to tie asset views to CRM Opportunities.
- 03 Expose CRM objects as Postgres tables the Heroku application can query and join directly
- 04 Sync Heroku Postgres into a warehouse for reporting without running ETL dynos
Common sync patterns
Product events onto CRM records
Signup, usage, or lifecycle changes written to Postgres Heroku sync onto the matching records in Seismic, giving go-to-market teams live product context.
Internal tools without API code
Back-office apps read and write the synced tables; Stacksync handles the Seismic API, limits, and retries.
Trigger workflows from CRM changes
Field and stage updates in Seismic arrive as row changes in Postgres Heroku, ready to drive jobs and notifications.
What you can sync between Postgres Heroku and Seismic
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.
| Postgres Heroku objects | Seismic objects | How this pairing syncs | |
|---|---|---|---|
| Materialized Views Precomputed result sets synced outward on refresh. | LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. | Materialized Views is specific to Postgres Heroku and LiveSend Links to Seismic — each maps to any object or custom field on the other side. | |
| Schemas Namespaces that scope which tables a sync reads and writes. | Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. | Schemas is specific to Postgres Heroku and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side. | |
| Primary and Unique Keys Match keys for idempotent upserts from connected systems. | Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. | Primary and Unique Keys is specific to Postgres Heroku and Reporting Activities to Seismic — each maps to any object or custom field on the other side. | |
| JSONB Columns Semi-structured payloads for nested SaaS objects and metadata. | Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. | JSONB Columns is specific to Postgres Heroku and Library Content to Seismic — each maps to any object or custom field on the other side. | |
| Sequences Generate surrogate keys for rows created by inbound syncs. | Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. | Sequences is specific to Postgres Heroku and Content Versions to Seismic — each maps to any object or custom field on the other side. | |
| Follower Databases Heroku-managed read replicas usable as low-impact sync sources. | Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. | Follower Databases is specific to Postgres Heroku and Users to Seismic — each maps to any object or custom field on the other side. |
How changes propagate between Postgres Heroku and Seismic
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.
Postgres Heroku Seismic 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 Seismic through its API, with automatic retries and rate-limit backoff.
Seismic Postgres Heroku Sub-second propagation
DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.
DeliveryEach detected change is applied to Postgres Heroku as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- Postgres Heroku: No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan.
- Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.

How the Postgres Heroku and Seismic connectors work
Postgres Heroku
- Integration surface
- SQL wire protocol (standard PostgreSQL)
- Authentication
- Database credentials from the Heroku DATABASE_URL config var; SSL required
- Change detection
- Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings

- Rate limits
- No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan
Seismic
- Integration surface
- REST Integration APIs and Reporting API v2
- Authentication
- OAuth 2.0 / OpenID Connect; Bearer token in the Authorization header, via Authorization Code (user context) or client-credentials app-only flows
- Change detection
- Webhooks for content, version, user, group, workflow, DSR, and LiveSend events; the Reporting API v2 is polled for batch historical extracts (ETL-oriented, not high-frequency)

FAQ
Postgres Heroku and Seismic integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Postgres Heroku and Seismic: authenticate both systems, choose the objects to sync (such as Postgres Heroku's Materialized Views and Schemas), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Seismic: Webhook events are tenant-scoped and can be filtered by attributes like contentId, teamSiteId, tenantId, and format using JSONPath or regex expressions. Postgres Heroku: Heroku Postgres is standard PostgreSQL, so any Postgres client, driver, or SQL tool connects unchanged. Stacksync's field mapping accounts for these differences between Postgres Heroku and Seismic 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 Postgres Heroku and Seismic records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Postgres Heroku and Seismic connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Postgres Heroku–Seismic integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Postgres Heroku and Seismic. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Postgres Heroku: Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings. On Seismic: Webhooks for content, version, user, group, workflow, DSR, and LiveSend events; the Reporting API v2 is polled for batch historical extracts (ETL-oriented, not high-frequency). Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
