Why teams connect Affinity and OpenSearch

Treat Affinity 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 Opportunities, Field Values, Notes, Interactions from Affinity into Index templates, Ingest pipelines, Data streams, Snapshots in OpenSearch with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Affinity 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

  • Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
  • Sync notes and reminders into project or task systems used outside the deal team.
  • Stream CRM records such as accounts, contacts, and tickets into OpenSearch to power internal search across customer data.
  • Sync product catalogs from an ERP or database into the indexes that back storefront search.

Product events onto CRM records

Signup, usage, or lifecycle changes written to OpenSearch sync onto the matching records in Affinity, 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 Affinity API, limits, and retries.

Trigger workflows from CRM changes

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

What you can sync between Affinity 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.

Affinity objects OpenSearch objects
Opportunities Deal records tracked on lists and synced with pipeline reporting. Documents JSON records written via the index and bulk APIs and read via search queries
Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills
Notes Meeting and call notes synced for record-keeping in other systems. Index templates Mapping and settings presets applied to new indexes a sync creates
Interactions Automatically captured emails and meetings, read for activity reporting. Ingest pipelines Server-side processors that transform documents as they are written
Reminders Follow-up tasks associated with people and organizations. Data streams Append-oriented time-series storage for logs and events pushed from source systems
Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. Snapshots Backup artifacts, relevant when reseeding an index from a repository
