Two-way sync
Changes in Firebase or Outreach instantly reflect in both systems. No stale data, no manual imports.
Keep Firebase and Outreach in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Prospects, Accounts, Sequences, Sequence states from Outreach 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 Outreach 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.
Accounts, contacts, and custom objects from Outreach become tables in Firebase you can join with application data directly.
Signup, usage, or lifecycle changes written to Firebase sync onto the matching records in Outreach, giving go-to-market teams live product context.
Back-office apps read and write the synced tables; Stacksync handles the Outreach API, limits, and retries.
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 | Outreach objects | |
|---|---|---|
| Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Mailboxes Connected sending accounts referenced when attributing outbound activity | |
| Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Prospects The people being engaged; the main record kept in sync with the CRM | |
| Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | Accounts Companies grouping prospects, aligned with CRM account ownership | |
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Sequences Multi-step cadences; synced as reference data for enrollment automation | |
| Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. | Sequence states Per-prospect enrollments; writing one adds a prospect to a cadence | |
| Authentication Users User accounts read into CRMs and warehouses for customer records. | Mailings Sent emails with engagement data, pulled for activity analytics |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Firebase–Outreach connection.
Changes in Firebase or Outreach instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Firebase or Outreach data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Firebase or Outreach record.
Track your Firebase ⇄ Outreach sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Firebase and Outreach.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Firebase and Outreach with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Firebase and Outreach objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Firebase and Outreach: 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.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Firebase and Outreach connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Firebase–Outreach integration in-house.
Yes — Stacksync ships production-grade connectors for both Firebase and Outreach. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Firebase: Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes. On Outreach: Webhook subscriptions on resource create, update, and destroy events, plus polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Outreach side: Prospects, Accounts, Sequences, Sequence states, plus custom fields where Outreach 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.
