Why teams connect Firebase and Ukg Ready
Put your workforce data where your apps can reach it: Firebase and Ukg Ready share the same people, positions, and org structure in real time.
Ukg Ready 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: Reports (Report-as-a-Service), Employees, Employment / Positions, Compensation in Ukg Ready need to exist as queryable Firestore Collections, Firestore Documents, Subcollections, Realtime Database Nodes 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 Firestore Collections, Firestore Documents, Subcollections, Realtime Database Nodes in Firebase with Reports (Report-as-a-Service), Employees, Employment / Positions, Compensation in Ukg Ready field by field, in real time. You decide which system owns which fields — Ukg Ready 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 Combine Firebase Authentication users with billing and CRM records into one customer table.
- 02 Replace one-off Cloud Functions export code with managed, continuous sync.
- 03 Mirror Cost Centers/Groups and Compensation into finance and planning systems for headcount and budget reconciliation.
- 04 Two-way sync Employees and Employment/Position records with an operational Postgres database so internal apps and IT provisioning read job title, department, and status in SQL while HR edits in UKG Ready.
Common sync patterns
Computed and operational fields flow back
Values assembled or corrected in Firebase write onto the matching record in Ukg Ready where those fields are writable, keeping the people system enriched.
Mirror people records into the database
Records maintained in Ukg Ready land as queryable Firestore Collections, Firestore Documents, Subcollections, Realtime Database Nodes in Firebase, so internal apps and dashboards read live data instead of a periodic export.
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.
What you can sync between Firebase and Ukg Ready
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 | Ukg Ready objects | How this pairing syncs | |
|---|---|---|---|
| Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Accruals / Time Off PTO balances, requests, and approver status; read for liability reporting and requests can be created against employee records. | Firestore Collections is specific to Firebase and Accruals / Time Off to Ukg Ready — 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. | Payroll (Earnings / Deductions / Employee Payroll Runs) Earnings and deductions can be imported into pay runs; Employee Payroll Runs (gross, net, taxes) read back for GL posting and analytics. | Firestore Documents is specific to Firebase and Payroll (Earnings / Deductions / Employee Payroll Runs) to Ukg Ready — each maps to any object or custom field on the other side. | |
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Benefits Plan enrollments, coverage tiers, contributions, and effective dates; typically read into benefits or finance systems. | Subcollections is specific to Firebase and Benefits to Ukg Ready — 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. | Cost Centers / Groups Departments, locations, and hierarchy used as org structure; read to align headcount and budget models across systems. | Realtime Database Nodes is specific to Firebase and Cost Centers / Groups to Ukg Ready — each maps to any object or custom field on the other side. | |
| Authentication Users User accounts read into CRMs and warehouses for customer records. | Reports (Report-as-a-Service) Scheduled IBM Cognos extracts used for bulk historical pulls that the per-employee REST endpoints are not built for. | Authentication Users is specific to Firebase and Reports (Report-as-a-Service) to Ukg Ready — each maps to any object or custom field on the other side. | |
| Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. | Employees Core person records (demographics, contact info, status, work location); synced two-way and mapped to HRIS or person tables in a database. | Cloud Storage Objects is specific to Firebase and Employees to Ukg Ready — each maps to any object or custom field on the other side. |
How changes propagate between Firebase and Ukg Ready
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 Ukg Ready 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 Ukg Ready through its API, with automatic retries and rate-limit backoff.
Ukg Ready Firebase Sub-second propagation
DetectionUkg Ready notifies Stacksync of record changes through webhook events. UKG Webhooks for select events (employee.created, employee.updated, account/org changes) with HMAC signing.
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.
- Ukg Ready: Rate limits apply over roughly a 1-minute window and return HTTP 429 when exceeded (back off / exponential retry); UKG Webhooks run on a tiered quota with a free tier around 10,000 event notifications per month and 14-day event retention.

FAQ
Firebase and Ukg Ready integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Firebase and Ukg Ready: authenticate both systems, choose the objects to sync (such as Firebase's Firestore Collections and Firestore Documents), 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 Ukg Ready connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Firebase–Ukg Ready integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Firebase and Ukg Ready. 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 Ukg Ready: UKG Webhooks for select events (employee.created, employee.updated, account/org changes) with HMAC signing; broad change capture via polling REST endpoints with date filters or scheduled Report-as-a-Service extracts. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Firebase side: Firestore Collections, Firestore Documents, Subcollections, Realtime Database Nodes, plus custom fields where Firebase exposes them. On the Ukg Ready side: Reports (Report-as-a-Service), Employees, Employment / Positions, Compensation. 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.
