Why teams connect Google Cloud SQL and Kustomer

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

Stacksync mirrors Users, Teams, Tags, Notes from Kustomer into Views, Transaction logs, Instances, Databases in Google Cloud SQL 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

  • Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
  • Escalate conversation-derived signals into the CRM as tasks or opportunities
  • Keep an internal admin application backed by Cloud SQL consistent with an ERP or billing system.
  • Migrate from a self-managed database by syncing Cloud SQL and the legacy system during cutover.

Query the CRM like a database

Accounts, contacts, and custom objects from Kustomer become tables in Google Cloud SQL you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Google Cloud SQL 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 Google Cloud SQL 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.

Google Cloud SQL objects Kustomer objects
Databases Scope the tables included in a sync configuration. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline.
Schemas Namespace tables in PostgreSQL and SQL Server instances. Users Agent records map conversation ownership to people in other systems.
Tables Mapped directly to sync targets; schema changes can be propagated. Teams Team assignments support routing parity and reporting.
Rows Read and written by primary key during each sync cycle. Tags Labels on conversations and customers sync for categorization and analytics.
Views Read-only sources for shaping data before syncing it out. Notes Internal annotations carry context alongside synced conversations.
Transaction logs MySQL binlog or PostgreSQL WAL, the source for log-based change capture. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it.
