Why teams connect Attio and Firebase
Treat Attio 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 People, Companies, Users, Deals from Attio into Firestore Collections, Firestore Documents, Subcollections, Realtime Database Nodes in Firebase with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Attio 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 Attio aligned with a billing system or ERP on customer records and plan status.
- Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
- 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 Attio arrive as row changes in Firebase, ready to drive jobs and notifications.
Query the CRM like a database
Accounts, contacts, and custom objects from Attio 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 Attio, giving go-to-market teams live product context.
What you can sync between Attio and Firebase
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.
| Attio objects | Firebase objects | |
|---|---|---|
| Custom objects Workspace-defined objects that behave like standard ones in the API. | Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Subcollections Nested collections under documents, typically flattened into related tables during sync. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Authentication Users User accounts read into CRMs and warehouses for customer records. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. |

FAQ
Attio and Firebase integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Attio and Firebase: authenticate both systems, choose the objects to sync (such as Attio's Custom objects and People), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Attio: Webhooks on record and list-entry events, with polling as a fallback. On Firebase: Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Attio side: People, Companies, Users, Deals, plus custom fields where Attio exposes them. On the Firebase side: Firestore Collections, Firestore Documents, Subcollections, Realtime Database Nodes. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Attio and Firebase: Trigger workflows from CRM changes; Query the CRM like a database; Product events onto CRM records. Field and stage updates in Attio arrive as row changes in Firebase, ready to drive jobs and notifications.
-
Attio: REST API. Authentication: Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key). Firebase: REST and gRPC APIs, typically accessed through the Firebase Admin SDK. Authentication: Google service account credentials (IAM) for server-side access; Firebase Auth tokens for client contexts. Stacksync manages authentication, retries, and rate limits on both sides.
