Why teams connect Amazon RDS and Kustomer

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

Stacksync mirrors Tags, Notes, Customers, Conversations from Kustomer into Schemas, Tables, Views, Columns in Amazon RDS 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
  • Sync master data (customers, products, pricing) from an ERP into the RDS databases that power customer-facing apps
  • Use a read replica as the sync source to keep change capture load off the primary instance

Query the CRM like a database

Accounts, contacts, and custom objects from Kustomer become tables in Amazon RDS you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Amazon RDS sync onto the matching records in Kustomer, 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 Kustomer API, limits, and retries.

What you can sync between Amazon RDS 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.

Amazon RDS objects Kustomer objects
Tables The core sync target; rows map to records in connected SaaS systems. Notes Internal annotations carry context alongside synced conversations.
Views Read-side projections exposed to outbound syncs. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it.
Columns Field-level mapping targets, typed per the underlying engine. Conversations Support threads across channels sync outward for analytics and CRM context.
Primary and Unique Keys Match keys for idempotent upserts. Messages Individual messages within conversations support full-thread replication.
Read Replicas Low-impact read endpoints often used as the source side of a sync. Companies Organization records group customers and map to CRM accounts.
Stored Procedures Engine-specific logic that can react to synced rows. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline.
