Why teams connect Firebase and Navan

Work with Navan's financial data straight from Firebase: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Users, Card Transactions, Connect Transactions, Manual Transactions from Navan into Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections in Firebase and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Firebase, and rows your code writes or updates flow back into Navan with validation, so the finance system stays the system of record.

Common use cases

  • 01 Sync Users and department mappings from an HRIS into reporting tables so every transaction is attributed to a cost center and manager.
  • 02 Sync Card Transactions and Manual Transactions into Postgres or a warehouse so finance analyzes corporate spend in SQL without manual CSV exports.
  • 03 Write CRM-side changes (plan, status, owner) back into Firestore documents the app reads.
  • 04 Combine Firebase Authentication users with billing and CRM records into one customer table.

Common sync patterns

Query finance data like any other data

Customers, invoices, and payments from Navan live in Firebase as regular tables or collections your team can join, index, and query.

Internal tools without API plumbing

Build dashboards and back-office tools directly on Firebase; Stacksync handles the API calls, rate limits, and retries against Navan.

Write back safely

Updates written to the synced tables in Firebase propagate into Navan, so automations can create or correct finance records without custom integration code.

What you can sync between Firebase and Navan

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 Navan objects How this pairing syncs
Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Firestore Documents is specific to Firebase and Repayments, Fees, and Adjustments to Navan — each maps to any object or custom field on the other side.
Subcollections Nested collections under documents, typically flattened into related tables during sync. Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Subcollections is specific to Firebase and Users to Navan — 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. Card Transactions Navan physical and virtual card spend; read via GET, then GL codes, cost centers, and ERP sync status are written back per transaction through the transaction update endpoint. Realtime Database Nodes is specific to Firebase and Card Transactions to Navan — each maps to any object or custom field on the other side.
Authentication Users User accounts read into CRMs and warehouses for customer records. Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Authentication Users is specific to Firebase and Connect Transactions to Navan — 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. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Cloud Storage Objects is specific to Firebase and Manual Transactions to Navan — 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. Bookings Flight, hotel, rail, and car reservations from the Booking API; pulled read-only by createdFrom/createdTo date range for trip and travel-spend reporting. Cloud Functions Triggers is specific to Firebase and Bookings to Navan — each maps to any object or custom field on the other side.

How changes propagate between Firebase and Navan

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 Navan 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 Navan through its API, with automatic retries and rate-limit backoff.

Navan Firebase Sub-second propagation

DetectionNavan notifies Stacksync of record changes through webhook events. Navan's Expense API supports webhooks for transaction and expense events.

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.
  • Navan: Requests are throttled with HTTP 429 and Navan recommends retrying with exponential backoff; the Expense/Public API must first be enabled per account by Navan.

How the Firebase and Navan 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

Rate limits
Subject to Firestore's documented operation quotas and per-document write throughput limits

Navan

Integration surface
REST (Expense API and Booking API)
Authentication
OAuth 2.0 client-credentials flow; an admin creates a client_id and client_secret under Settings > Integrations and exchanges them at Navan's OAuth token endpoint for a short-lived bearer token that is refreshed on expiry (separate US and EU regional hosts)
Change detection
Navan's Expense API supports webhooks for transaction and expense events; sync engines also poll GET endpoints with date-range and updatedAt filters (createdFrom/createdTo for bookings) to backfill history and reconcile. There is no database-level CDC.
Capabilities

Rate limits
Requests are throttled with HTTP 429 and Navan recommends retrying with exponential backoff; the Expense/Public API must first be enabled per account by Navan.
