Why teams connect Firebase and Intercom

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

Stacksync mirrors Data Events, Custom Data Attributes, Tags, Segments from Intercom into Cloud Functions Triggers, Firestore Collections, Firestore Documents, Subcollections in Firebase with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Intercom 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 tickets into a warehouse for support analytics and SLA reporting
  • Keep custom data attributes updated from billing or ERP systems so message segments reflect current plan and spend
  • Mirror Firestore collections into Postgres or a warehouse to run SQL analytics on app data.
  • Write CRM-side changes (plan, status, owner) back into Firestore documents the app reads.

Trigger workflows from CRM changes

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

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to Firebase sync onto the matching records in Intercom, giving go-to-market teams live product context.

What you can sync between Firebase and Intercom

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.

Firebase objects Intercom objects
Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. Admins & Teams Teammate records map conversation ownership to CRM users.
Subcollections Nested collections under documents, typically flattened into related tables during sync. Articles Help center content is accessible via API for knowledge sync and audits.
Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. Contacts A single contact model covers both users and leads, distinguished by a role attribute.
Authentication Users User accounts read into CRMs and warehouses for customer records. Companies Company records group contacts and carry plan and account attributes used in segmentation.
Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. Conversations Support and sales threads sync outward for analytics and CRM context.
Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. Tickets Structured ticket records track issues alongside conversational threads.
