Why teams connect Firebase and Lusha
Mirror Lusha's data into Firebase so your own code can read and write it like any other table, with changes flowing both ways in seconds.
Lusha is a read-only source: Stacksync reads its data in real time and delivers it into Firebase, so Firebase always reflects the current state of Lusha — without exports, scripts, or schedulers.
Engineers integrate with tools like Lusha through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Firebase.
Stacksync mirrors Person Profiles, Company Profiles, Email Addresses, Phone Numbers from Lusha into Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections in Firebase and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Lusha, so the tool and the database never disagree.
Common use cases
- Enrich new CRM leads with work emails and direct dials the moment they are created.
- Backfill missing phone numbers on an existing contact list stored in a database or warehouse.
- Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.
- Mirror Firestore collections into Postgres or a warehouse to run SQL analytics on app data.
One integration pattern for the whole stack
Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
Read Lusha with a query
Records from Lusha are ordinary rows in Firebase; join them, index them, and use them in application logic without touching the vendor API.
Automate Lusha from your codebase
Write to the synced tables in Firebase and Stacksync propagates the change into Lusha, replacing custom integration code.
What you can sync between Firebase and Lusha
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 | Lusha objects | |
|---|---|---|
| Authentication Users User accounts read into CRMs and warehouses for customer records. | Person Profiles Contact-level enrichment results (work emails, phone numbers, title, company) returned per lookup. | |
| Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. | Company Profiles Firmographic records (industry, size, location) appended to account or company rows. | |
| Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Email Addresses Work emails written into CRM contact fields during enrichment. | |
| Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Phone Numbers Direct-dial and mobile numbers appended for outbound calling workflows. | |
| Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | Prospecting Results Search-based lists of people and companies matching filters, used to seed lead lists. | |
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Bulk Enrichment Requests Batch lookups that enrich multiple records per request, used to backfill large contact lists rather than one-off calls. |

How the Firebase and Lusha 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
Lusha
- Integration surface
- REST API
- Authentication
- API key
- Change detection
- Not event-driven; data is fetched on demand per lookup, so syncs poll or trigger enrichment when source records change
- Capabilities
- read
- Rate limits
- Lookups consume credits and are subject to the platform's API rate limits.
How it works

FAQ
Firebase and Lusha integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Firebase and Lusha — Lusha is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Firebase and Lusha connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Firebase–Lusha integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Firebase and Lusha. 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 Lusha: Not event-driven; data is fetched on demand per lookup, so syncs poll or trigger enrichment when source records change. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Lusha side: Person Profiles, Company Profiles, Email Addresses, Phone Numbers, plus custom fields where Lusha 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.
-
Lusha is a read-only source, so this integration runs one-way: Stacksync reads from Lusha in real time and delivers into Firebase. Field mapping and monitoring work the same as for two-way pairs.
