Why teams connect Crustdata and Firebase
Treat Crustdata like part of your database: its records live in Firebase as real tables, and writes in either place sync to the other in seconds.
Crustdata 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 Crustdata — without exports, scripts, or schedulers.
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.
Common use cases
- 01 Append enrichment at lead-capture time so new records arrive scored and routable.
- 02 Enrich CRM accounts with firmographics, headcount growth, and tech stack so scoring and routing run on complete data.
- 03 Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.
- 04 Mirror Firestore collections into Postgres or a warehouse to run SQL analytics on app data.
Common sync patterns
Product events onto CRM records
Signup, usage, or lifecycle changes written to Firebase sync onto the matching records in Crustdata, giving go-to-market teams live product context.
Internal tools without API code
Back-office apps read and write the synced tables; Stacksync handles the Crustdata API, limits, and retries.
Trigger workflows from CRM changes
Field and stage updates in Crustdata arrive as row changes in Firebase, ready to drive jobs and notifications.
What you can sync between Crustdata 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.
| Crustdata objects | Firebase objects | How this pairing syncs | |
|---|---|---|---|
| Companies Firmographic records — industry, size, funding, growth signals; read out to enrich CRM accounts and warehouse company tables. | Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. | Companies is specific to Crustdata and Realtime Database Nodes to Firebase — each maps to any object or custom field on the other side. | |
| People Contact and profile data for decision-makers; read into a CRM or outreach tool to fill missing titles, emails, and LinkedIn profiles. | Authentication Users User accounts read into CRMs and warehouses for customer records. | People is specific to Crustdata and Authentication Users to Firebase — each maps to any object or custom field on the other side. | |
| Headcount and Growth Metrics Time-series employee counts by department and region; read to score accounts on hiring momentum and expansion signals. | Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. | Headcount and Growth Metrics is specific to Crustdata and Cloud Storage Objects to Firebase — each maps to any object or custom field on the other side. | |
| Tech Stack Detected technologies per company; read to build segments and route accounts by the tools they already use. | Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Tech Stack is specific to Crustdata and Cloud Functions Triggers to Firebase — each maps to any object or custom field on the other side. | |
| Screener Results Saved company searches with filter criteria; read on a schedule so target-account lists in the CRM refresh as companies enter the criteria. | Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Screener Results is specific to Crustdata and Firestore Collections to Firebase — each maps to any object or custom field on the other side. | |
| Enrichment Responses Real-time enrichment lookups keyed by domain or profile URL; read to append fresh firmographic and contact data at form-fill or record-creation time. | Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | Enrichment Responses is specific to Crustdata and Firestore Documents to Firebase — each maps to any object or custom field on the other side. |
How changes propagate between Crustdata 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.
Crustdata Firebase Interval-based propagation
DetectionStacksync polls Crustdata for changes on an incremental schedule, reading only records changed since the previous pass. Pull-based: real-time enrichment endpoints for on-demand lookups plus periodic re-pulls of screeners and datasets.
DeliveryEach detected change is written to Firebase through its API, with automatic retries and rate-limit backoff.
Firebase Crustdata 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.
DeliveryCrustdata does not accept inbound record writes, so this direction carries requests rather than records: Crustdata's output flows back as field updates on the originating Firebase records.
Rate-limit considerations
- Crustdata: Requests are metered by plan credits and per-minute rate limits; bulk dataset pulls are the efficient path for large refreshes rather than per-record enrichment calls.
- Firebase: Subject to Firestore's documented operation quotas and per-document write throughput limits.

FAQ
Crustdata and Firebase integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Crustdata and Firebase — Crustdata 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.
-
On the Crustdata side: Companies, People, Headcount and Growth Metrics, Tech Stack, plus custom fields where Crustdata 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.
-
Crustdata is a read-only source, so this integration runs one-way: Stacksync reads from Crustdata in real time and delivers into Firebase. Field mapping and monitoring work the same as for two-way pairs.
-
Common patterns for Crustdata and Firebase: Product events onto CRM records; Internal tools without API code; Trigger workflows from CRM changes. Signup, usage, or lifecycle changes written to Firebase sync onto the matching records in Crustdata, giving go-to-market teams live product context.
-
Crustdata: REST API (JSON). Authentication: API token — Authorization: Token header issued per workspace. 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. Stacksync manages authentication, retries, and rate limits on both sides.
-
Crustdata: Enrichment is credit-metered by plan; high-volume refreshes should use dataset/bulk endpoints rather than per-record lookups. Firebase: Firestore documents are schemaless and support nested maps and arrays, so syncs define field mappings per document path rather than from a fixed schema. Stacksync's field mapping accounts for these differences between Crustdata and Firebase without custom code.
