Why teams connect Firebase and Onelogin
Close the gap between your application data and your directory: Firebase and Onelogin share users, groups, and access in real time, in both directions.
Onelogin is the system of record for who people are and what they can reach: users, the groups they belong to, and the applications assigned to them. Firebase holds the operational data those same people show up in, whether an employee or member table that decides who should have an account at all, a customers list, or the rows an application checks before it authorizes an action. The two describe overlapping users and groups, and when a nightly export or a hand-run script is all that connects them, accounts lag joiners and leavers and the application authorizes against a stale picture of who has access.
Stacksync syncs Firestore Documents, Subcollections, Realtime Database Nodes, Authentication Users in Firebase with Events, Authentication factors (MFA), Custom user fields, Users in Onelogin field by field, in real time, and in both directions. You decide which system owns which fields, with the directory holding credentials and group membership and the database holding the source list of people who should exist at all, and Stacksync keeps every copy consistent, resolving conflicts by rules you set. A person added to a table becomes an account within seconds, a departure disables one just as fast, and the directory's users and groups are always present in your tables as ordinary rows.
Common use cases
- 01 Mirror Firestore collections into Postgres or a warehouse to run SQL analytics on app data.
- 02 Write CRM-side changes (plan, status, owner) back into Firestore documents the app reads.
- 03 Read Users, Apps, and Groups into a database for identity, license, and app-assignment inventory across the OneLogin account.
- 04 Two-way sync Users between OneLogin and an HRIS or Postgres so new hires, attribute changes, and terminations provision and deprovision SSO accounts automatically.
Common sync patterns
Keep group and role membership aligned
A group or role change made in either system updates the other, so the entitlements an application enforces match what the directory grants.
One profile, kept current
A name, department, email, or manager corrected in either system updates the other, so the profile the directory shows and the data the application reads stop drifting apart.
Provision accounts from the source of truth
When a person is added to the employee, member, or customer table in Firebase, Stacksync creates the matching user in Onelogin with the right attributes, so access starts from live data instead of a manual ticket.
What you can sync between Firebase and Onelogin
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 | Onelogin objects | How this pairing syncs | |
|---|---|---|---|
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Users User accounts (email, username, custom attributes, status, roles); full CRUD via the v2 Users API - create, update, delete, set password, lock/unlock, and add or remove role assignments. | Subcollections is specific to Firebase and Users to Onelogin — 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. | Roles Roles that bundle app access; created, updated, and deleted via the Roles API, with users, admins, and apps assigned to each role. | Realtime Database Nodes is specific to Firebase and Roles to Onelogin — each maps to any object or custom field on the other side. | |
| Authentication Users User accounts read into CRMs and warehouses for customer records. | Apps (app instances) Connected SAML/OIDC application configs on the account; create, update, delete, and assign to users and roles - the writable app catalog. | Authentication Users is specific to Firebase and Apps (app instances) to Onelogin — 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. | Groups Account groups used for mapping and reporting; listed and read through the API, which has no create or update endpoint, so groups are read-only. | Cloud Storage Objects is specific to Firebase and Groups to Onelogin — each maps to any object or custom field on the other side. | |
| Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | Mappings (mapping rules) Attribute-driven rules that assign roles and app access; full CRUD via the Mappings API, then reapplied across matching users. | Cloud Functions Triggers is specific to Firebase and Mappings (mapping rules) to Onelogin — 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. | Events Audit log of every authentication and admin action; read-only, filtered by since/until, and pushed live through the Event Webhook. | Firestore Collections is specific to Firebase and Events to Onelogin — each maps to any object or custom field on the other side. |
How changes propagate between Firebase and Onelogin
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 Onelogin 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 Onelogin through its API, with automatic retries and rate-limit backoff.
Onelogin Firebase Sub-second propagation
DetectionOnelogin notifies Stacksync of record changes through webhook events. Event Webhook (Event Broadcaster) posts batches of Event objects to a registered endpoint in near real time.
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.
- Onelogin: Account-level limit of 5,000 API calls per hour shared across all access tokens; responses carry X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset, over-limit calls return HTTP 429, and the count resets each hour. Paid plans can request an increase.

How the Firebase and Onelogin 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
Onelogin
- Integration surface
- OneLogin API (REST, v1 and v2 resource endpoints on <subdomain>.onelogin.com) plus the Event Webhook (Event Broadcaster) for event delivery
- Authentication
- OAuth 2.0 client credentials - an admin generates an API credential pair (client_id + client_secret) in the OneLogin portal and exchanges it at POST /auth/oauth2/v2/token for a bearer access token sent on every call; each credential carries a scope (Manage all, Manage users, Read users, etc.) that governs read vs write.
- Change detection
- Event Webhook (Event Broadcaster) posts batches of Event objects to a registered endpoint in near real time; the Events API also supports polling with since/until time filters and pagination for historical backfill.
- Capabilities
- read · write · webhooks
- Rate limits

FAQ
Firebase and Onelogin integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Firebase and Onelogin: authenticate both systems, choose the objects to sync (such as Firebase's Subcollections and Realtime Database Nodes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Firebase: Snapshot listeners deliver document changes to connected clients in real time, which is the platform's native change-notification mechanism. Onelogin: Auth is OAuth 2.0 client credentials - a client_id/client_secret pair exchanged at /auth/oauth2/v2/token for a bearer token; the credential's scope (e.g. Manage users vs Read) decides what it can write. Stacksync's field mapping accounts for these differences between Firebase and Onelogin without custom code.
-
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 Onelogin records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Firebase and Onelogin connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Firebase–Onelogin integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Firebase and Onelogin. 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 Onelogin: Event Webhook (Event Broadcaster) posts batches of Event objects to a registered endpoint in near real time; the Events API also supports polling with since/until time filters and pagination for historical backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
