Why teams connect Elasticsearch and Kustomer

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

Stacksync mirrors Customers, Conversations, Messages, Companies from Kustomer into Index mappings, Aliases, Data streams, Ingest pipelines in Elasticsearch 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

  • Escalate conversation-derived signals into the CRM as tasks or opportunities
  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • Push product catalog data from an ERP or commerce database into Elasticsearch for storefront search.
  • Mirror support tickets into an index used for full-text search and agent-assist tooling.

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to Elasticsearch 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 Elasticsearch 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.

Elasticsearch objects Kustomer objects
Data streams Append-only targets for time-series or event data pushed from source systems. Messages Individual messages within conversations support full-thread replication.
Ingest pipelines Server-side transforms applied to documents as a sync writes them. Companies Organization records group customers and map to CRM accounts.
Index templates Reusable settings and mappings applied automatically to new indices a sync creates. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline.
Indices Target containers for synced records; each holds a table-like collection of JSON documents. Users Agent records map conversation ownership to people in other systems.
Documents The unit of sync; JSON records created, updated, and deleted by _id. Teams Team assignments support routing parity and reporting.
Index mappings Field type definitions that determine how synced fields are indexed and queried. Tags Labels on conversations and customers sync for categorization and analytics.

How the Elasticsearch and Kustomer connectors work

Elasticsearch

Integration surface
REST API (JSON over HTTP)
Authentication
API keys or basic authentication; Elastic Cloud also issues service account tokens
Change detection
Polling on timestamp or sequence fields; Elasticsearch does not expose a native change feed or webhooks
Capabilities

Rate limits
No fixed request quota; throughput is bounded by cluster sizing, thread pools, and bulk queue capacity

Kustomer

Integration surface
REST API
Authentication
API key used as a bearer token, scoped by role
Change detection
Outbound webhooks on record events, plus polling for backfill
Capabilities
