Why teams connect AWS Aurora PostgreSQL and Kustomer

Treat Kustomer like part of your database: its records live in AWS Aurora PostgreSQL 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 AWS Aurora PostgreSQL, where it can be queried and joined like everything else.

Stacksync mirrors Custom Objects (Klasses), Users, Teams, Tags from Kustomer into Views and materialized views, Foreign keys, Replication slots and publications, Databases and schemas in AWS Aurora PostgreSQL with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Kustomer 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

  • Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
  • Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • Expose ERP records such as customers, orders, and invoices as Postgres tables the engineering team can query and update with plain SQL.
  • Capture row-level changes with logical replication and propagate them to SaaS tools without batch jobs.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Kustomer API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Kustomer arrive as row changes in AWS Aurora PostgreSQL, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Kustomer become tables in AWS Aurora PostgreSQL you can join with application data directly.

What you can sync between AWS Aurora PostgreSQL and Kustomer

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.

AWS Aurora PostgreSQL objects Kustomer objects
Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. Messages Individual messages within conversations support full-thread replication.
Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. Companies Organization records group customers and map to CRM accounts.
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline.
Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Users Agent records map conversation ownership to people in other systems.
Replication slots and publications The logical replication objects that power log-based CDC. Teams Team assignments support routing parity and reporting.
Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. Tags Labels on conversations and customers sync for categorization and analytics.
