Why teams connect Azure Cosmos DB and Kustomer

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

Stacksync mirrors Companies, Custom Objects (Klasses), Users, Teams from Kustomer into Change feed entries, Stored procedures and triggers, Databases, Containers in Azure Cosmos DB 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

  • Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
  • Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.
  • Consolidate documents from multiple containers into a single reporting store.

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 Azure Cosmos DB, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Kustomer become tables in Azure Cosmos DB you can join with application data directly.

What you can sync between Azure Cosmos DB 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.

Azure Cosmos DB objects Kustomer objects
Containers The unit of partitioning and throughput; each container maps to a synced collection. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Conversations Support threads across channels sync outward for analytics and CRM context.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Messages Individual messages within conversations support full-thread replication.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Companies Organization records group customers and map to CRM accounts.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline.
Databases Top-level namespaces that scope containers and throughput provisioning. Users Agent records map conversation ownership to people in other systems.
