Why teams connect Firebase and Twenty CRM
Treat Twenty CRM 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 Custom Objects, Attachments, Workspace Members, People from Twenty CRM into Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections in Firebase with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Twenty CRM 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 Opportunities into a finance system to keep revenue forecasts current.
- Mirror support tickets or tasks between Twenty and an operations tool.
- 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.
Internal tools without API code
Back-office apps read and write the synced tables; Stacksync handles the Twenty CRM API, limits, and retries.
Trigger workflows from CRM changes
Field and stage updates in Twenty CRM arrive as row changes in Firebase, ready to drive jobs and notifications.
Query the CRM like a database
Accounts, contacts, and custom objects from Twenty CRM become tables in Firebase you can join with application data directly.
What you can sync between Firebase and Twenty CRM
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 | Twenty CRM objects | |
|---|---|---|
| Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Attachments Files linked to records. | |
| Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Workspace Members User accounts used for record ownership and assignment mapping. | |
| Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | People Individual contact records with emails, phones, and company links; a core target for contact syncs. | |
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Companies Account-level records that group people and opportunities. | |
| Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. | Opportunities Deal records tracked through pipeline stages, synced for forecasting. | |
| Authentication Users User accounts read into CRMs and warehouses for customer records. | Tasks To-dos linked to people, companies, or deals. |

FAQ
Firebase and Twenty CRM integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Firebase and Twenty CRM: authenticate both systems, choose the objects to sync (such as Firebase's Cloud Functions Triggers and Firestore Collections), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the Twenty CRM side: Custom Objects, Attachments, Workspace Members, People, plus custom fields where Twenty CRM exposes them. On the Firebase side: Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections. 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 Firebase and Twenty CRM: Internal tools without API code; Trigger workflows from CRM changes; Query the CRM like a database. Back-office apps read and write the synced tables; Stacksync handles the Twenty CRM API, limits, and retries.
-
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. Twenty CRM: GraphQL and REST APIs. Authentication: API key. Stacksync manages authentication, retries, and rate limits on both sides.
-
Twenty CRM: Twenty is open source and self-hostable, backed by PostgreSQL, with an object and field model that is metadata-driven and editable from the UI. Firebase: Snapshot listeners deliver document changes to connected clients in real time, which is the platform's native change-notification mechanism. Stacksync's field mapping accounts for these differences between Firebase and Twenty CRM without custom code.
