Why teams connect Kustomer and OpenSearch

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

Stacksync mirrors Notes, Customers, Conversations, Messages from Kustomer into Data streams, Snapshots, Indexes, Documents in OpenSearch 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
  • Sync product catalogs from an ERP or database into the indexes that back storefront search.
  • Keep Postgres as the source of truth while mirroring rows to OpenSearch for full-text and vector queries.

Product events onto CRM records

Signup, usage, or lifecycle changes written to OpenSearch 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 OpenSearch, ready to drive jobs and notifications.

What you can sync between Kustomer and OpenSearch

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.

Kustomer objects OpenSearch objects
Companies Organization records group customers and map to CRM accounts. Index templates Mapping and settings presets applied to new indexes a sync creates
Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. Ingest pipelines Server-side processors that transform documents as they are written
Users Agent records map conversation ownership to people in other systems. Data streams Append-oriented time-series storage for logs and events pushed from source systems
Teams Team assignments support routing parity and reporting. Snapshots Backup artifacts, relevant when reseeding an index from a repository
Tags Labels on conversations and customers sync for categorization and analytics. Indexes The core container; synced records land in indexes with defined mappings
Notes Internal annotations carry context alongside synced conversations. Documents JSON records written via the index and bulk APIs and read via search queries
