Why teams connect Firebase and Salesforce

Treat Salesforce 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 Contacts, Leads, Opportunities, Cases from Salesforce 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 Salesforce 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

  • Write product usage metrics computed in a warehouse onto Account and Contact fields so reps see adoption signals on the record.
  • Trigger provisioning or billing changes in an operational database when an Opportunity moves to closed-won.
  • Replace one-off Cloud Functions export code with managed, continuous sync.
  • Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.

Trigger workflows from CRM changes

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

Query the CRM like a database

Accounts, contacts, and custom objects from Salesforce 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 Salesforce, giving go-to-market teams live product context.

What you can sync between Firebase and Salesforce

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 Salesforce objects
Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. Tasks and Events Activity records; usually read-only in syncs to feed activity reporting.
Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. Products and Price Books Catalog and pricing data; commonly mastered in an ERP and written into Salesforce.
Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. Custom Objects Org-specific tables with the __c suffix; discoverable via describe metadata so field mappings can be generated.
Subcollections Nested collections under documents, typically flattened into related tables during sync. Accounts Company records that anchor most syncs; typically mapped to customer tables in a database or ERP.
Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records.
Authentication Users User accounts read into CRMs and warehouses for customer records. Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines.
What ships with Firebase ⇄ Salesforce

Connect Firebase and Salesforce for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Firebase–Salesforce connection.

Real-time

Two-way sync

Changes in Firebase or Salesforce instantly reflect in both systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever Firebase or Salesforce data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single Firebase or Salesforce record.

Observability

Monitoring

Track your Firebase ⇄ Salesforce sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Firebase and Salesforce.

How the Firebase and Salesforce connectors work

Firebase

Integration surface
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
Change detection
Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes
Capabilities
read · write
Rate limits
Subject to Firestore's documented operation quotas and per-document write throughput limits

Salesforce

Integration surface
REST, SOAP, and Bulk APIs
Authentication
OAuth login via a Salesforce user (browser-based authorization flow); requires "API Enabled" permission for polling mode, plus "Author Apex" and "Customize Application" OR "Modify All Data" for trigger mode
Change detection
Apex triggers are used whenever possible (Salesforce actively notifies Stacksync via an Apex trigger + callout class + remote site setting)
Capabilities
read · write · CDC
Rate limits
Daily API request allocations vary by edition and license count.
