Why teams connect BetterContact and Firebase
Mirror BetterContact's data into Firebase so your own code can read and write it like any other table, with changes flowing both ways in seconds.
BetterContact 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 BetterContact — without exports, scripts, or schedulers.
Engineers integrate with tools like BetterContact 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 Company, Lead Finder Search, Enrichment Request, Enriched Contact from BetterContact into Cloud Functions Triggers, Firestore Collections, Firestore Documents, Subcollections 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 BetterContact, so the tool and the database never disagree.
Common use cases
- 01 Backfill a warehouse of contacts with waterfall enrichment across 20+ data providers.
- 02 Feed outbound sequencing tools with verified contact data before campaigns launch.
- 03 Combine Firebase Authentication users with billing and CRM records into one customer table.
- 04 Replace one-off Cloud Functions export code with managed, continuous sync.
Common sync patterns
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 BetterContact with a query
Records from BetterContact are ordinary rows in Firebase; join them, index them, and use them in application logic without touching the vendor API.
Automate BetterContact from your codebase
Write to the synced tables in Firebase and Stacksync propagates the change into BetterContact, replacing custom integration code.
What you can sync between BetterContact 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.
| BetterContact objects | Firebase objects | How this pairing syncs | |
|---|---|---|---|
| Enriched Contact Verified work emails and mobile numbers with job title, LinkedIn profile, location, and skills. | Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Enriched Contact is specific to BetterContact and Firestore Collections to Firebase — each maps to any object or custom field on the other side. | |
| Company Company data returned with each contact: name, domain, HQ location, industry, employee count. | Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | Company is specific to BetterContact and Firestore Documents to Firebase — each maps to any object or custom field on the other side. | |
| Lead Finder Search Prospect discovery by people and company filters, returning enriched lead profiles. | Subcollections Nested collections under documents, typically flattened into related tables during sync. | Lead Finder Search is specific to BetterContact and Subcollections to Firebase — each maps to any object or custom field on the other side. | |
| Enrichment Request Batch or single submissions of up to 100 contacts per request for waterfall enrichment. | Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. | Enrichment Request is specific to BetterContact and Realtime Database Nodes to Firebase — each maps to any object or custom field on the other side. |
How changes propagate between BetterContact and Firebase
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
BetterContact Firebase Sub-second propagation
DetectionBetterContact notifies Stacksync of record changes through webhook events. Job-based delivery — enrichment results arrive by webhook push or polling of the results endpoint.
DeliveryEach detected change is written to Firebase through its API, with automatic retries and rate-limit backoff.
Firebase BetterContact Interval-based propagation
DetectionStacksync polls Firebase for changes on an incremental schedule, reading only records changed since the previous pass. Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes.
DeliveryBetterContact does not accept inbound record writes, so this direction carries requests rather than records: BetterContact's output flows back as field updates on the originating Firebase records.
Rate-limit considerations
- BetterContact: Batches capped at 100 contacts per enrichment request.
- Firebase: Subject to Firestore's documented operation quotas and per-document write throughput limits.

FAQ
BetterContact and Firebase integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between BetterContact and Firebase — BetterContact 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.
-
Yes — Stacksync ships production-grade connectors for both BetterContact and Firebase. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on BetterContact: Job-based delivery — enrichment results arrive by webhook push or polling of the results endpoint; there is no persistent record store to watch. 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 BetterContact side: Company, Lead Finder Search, Enrichment Request, Enriched Contact, plus custom fields where BetterContact exposes them. On the Firebase side: Cloud Functions Triggers, Firestore Collections, Firestore Documents, Subcollections. Stacksync auto-detects both schemas and converts types between the two systems.
-
BetterContact is a read-only source, so this integration runs one-way: Stacksync reads from BetterContact in real time and delivers into Firebase. Field mapping and monitoring work the same as for two-way pairs.
-
Common patterns for BetterContact and Firebase: One integration pattern for the whole stack; Read BetterContact with a query; Automate BetterContact from your codebase. Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
