Why teams connect Google Cloud Spanner and Kustomer

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

Stacksync mirrors Teams, Tags, Notes, Customers from Kustomer into Change streams, Views, Databases, Tables in Google Cloud Spanner 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
  • Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.
  • Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.

Product events onto CRM records

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

Trigger workflows from CRM changes

Field and stage updates in Kustomer arrive as row changes in Google Cloud Spanner, ready to drive jobs and notifications.
