Why teams connect Freshsales and OpenSearch

Treat Freshsales 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 Deals, Tasks, Appointments, Notes from Freshsales into Ingest pipelines, Data streams, Snapshots, Indexes in OpenSearch with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Freshsales 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

  • Sync sales activities and appointments into analytics tools for rep productivity reporting.
  • Two-way sync of contacts and accounts between Freshsales and a Postgres database so product and data teams query CRM data with SQL.
  • Backfill or rebuild indexes from a database after mapping changes without hand-written ETL.
  • Stream CRM records such as accounts, contacts, and tickets into OpenSearch to power internal search across customer data.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Freshsales API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Freshsales arrive as row changes in OpenSearch, ready to drive jobs and notifications.

Query the CRM like a database

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

What you can sync between Freshsales 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.

Freshsales objects OpenSearch objects
Products Catalog items attached to deals for line-level revenue data. Snapshots Backup artifacts, relevant when reseeding an index from a repository
Contacts Person records carrying lifecycle stages; the main entity for two-way CRM syncs. Indexes The core container; synced records land in indexes with defined mappings
Accounts Company records kept aligned with billing, ERP, and warehouse tables. Documents JSON records written via the index and bulk APIs and read via search queries
Deals Pipeline records synced to a warehouse for revenue reporting. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills
Tasks Rep to-dos created from external triggers or synced for productivity reporting. Index templates Mapping and settings presets applied to new indexes a sync creates
Appointments Scheduled meetings readable for activity analytics. Ingest pipelines Server-side processors that transform documents as they are written
