Why teams connect Firebase and Smartrecruiters
Put your workforce data where your apps can reach it: Firebase and Smartrecruiters share the same people, positions, and org structure in real time.
Smartrecruiters is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. Firebase is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Candidates, Applications, Jobs, Job Postings in Smartrecruiters need to exist as queryable Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections, Firestore Documents in Firebase before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.
Stacksync syncs Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections, Firestore Documents in Firebase with Candidates, Applications, Jobs, Job Postings in Smartrecruiters field by field, in real time. You decide which system owns which fields — Smartrecruiters typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.
The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.
Common use cases
- 01 Replace one-off Cloud Functions export code with managed, continuous sync.
- 02 Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.
- 03 Subscribe to the Webhooks API to react to new applications and status changes in near real time across downstream systems.
- 04 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update hiring status, tags, and custom fields in SQL while recruiters keep working in SmartRecruiters.
Common sync patterns
One directory of record
When a person record is added, changed, or deactivated in either system, the matching row in the other stays current, ending dual maintenance.
Reporting and analytics on current data
Candidates, Applications, Jobs, Job Postings replicate into Firebase where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.
Org and structure stay aligned
Groups, departments, managers, and reporting lines from Smartrecruiters stay consistent in Firebase, so hierarchy-driven logic and permissions don't drift.
What you can sync between Firebase and Smartrecruiters
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 | Smartrecruiters objects | How this pairing syncs | |
|---|---|---|---|
| Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Applications Links a Candidate to a Job and carries the current hiring status and source; created and advanced through statuses (screening, interview, offer, hired, rejected) via the Application API. | Cloud Functions Triggers is specific to Firebase and Applications to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Jobs Requisitions (positions) with openings, departments, locations, and hiring team; created, patched, and read out for requisition and time-to-fill reporting via the Jobs API. | Firestore Collections is specific to Firebase and Jobs to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | Job Postings Job ads and publications pushed to the career site and job boards; created and managed via the job publication endpoints (rate-limited to 2 requests/sec). | Firestore Documents is specific to Firebase and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. | Subcollections is specific to Firebase and Interviews to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. | Offers Offer records tied to an Application with status, custom offer fields, and offer documents; readable and writable, commonly synced to an HRIS on hire (documents endpoint limited to 2 requests/sec). | Realtime Database Nodes is specific to Firebase and Offers to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Authentication Users User accounts read into CRMs and warehouses for customer records. | Users Company users (recruiters, hiring managers) with roles, access groups, and activation state; read and written via the User Management API. | Authentication Users is specific to Firebase and Users to Smartrecruiters — each maps to any object or custom field on the other side. |
How changes propagate between Firebase and Smartrecruiters
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.
Firebase Smartrecruiters 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.
DeliveryEach detected change is written to Smartrecruiters through its API, with automatic retries and rate-limit backoff.
Smartrecruiters Firebase Sub-second propagation
DetectionSmartrecruiters notifies Stacksync of record changes through webhook events. Webhooks API — subscribe to events (new application, candidate updated, status changed) delivered with a signing secret and retrievable callback logs.
DeliveryEach detected change is written to Firebase through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Firebase: Subject to Firestore's documented operation quotas and per-document write throughput limits.
- Smartrecruiters: Per API credential: most endpoints allow up to 10 requests/sec (job publication and offer documents 2/sec), plus a concurrency limiter of up to 8 simultaneous requests (GET /candidates capped at 1). Exceeding returns 429; responses carry X-RateLimit-Limit/Remaining and concurrent-limit headers.

FAQ
Firebase and Smartrecruiters integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Firebase and Smartrecruiters: 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 is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Firebase and Smartrecruiters records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Firebase and Smartrecruiters connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Firebase–Smartrecruiters integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Firebase and Smartrecruiters. 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 Smartrecruiters: Webhooks API — subscribe to events (new application, candidate updated, status changed) delivered with a signing secret and retrievable callback logs; otherwise poll list endpoints with updated-after-style filters. No log-based change data capture. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Firebase side: Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections, Firestore Documents, plus custom fields where Firebase exposes them. On the Smartrecruiters side: Candidates, Applications, Jobs, Job Postings. Stacksync auto-detects both schemas and converts types between the two systems.
