Why teams connect Navan and Neo4j

Work with Navan's financial data straight from Neo4j: 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 Repayments, Fees, and Adjustments, Users, Card Transactions, Connect Transactions from Navan into Properties, Labels, Indexes & Constraints, Databases in Neo4j and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Neo4j, 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 Feed identity and access data into a graph for entitlement and blast-radius analysis.
  • 04 Write computed relationship scores (fraud, influence, similarity) back to operational systems.

Common sync patterns

Query finance data like any other data

Customers, invoices, and payments from Navan live in Neo4j 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 Neo4j; Stacksync handles the API calls, rate limits, and retries against Navan.

Write back safely

Updates written to the synced tables in Neo4j propagate into Navan, so automations can create or correct finance records without custom integration code.

What you can sync between Navan and Neo4j

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.

Navan objects Neo4j objects How this pairing syncs
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. Properties Key-value attributes on both nodes and relationships, mapped from source fields. Card Transactions is specific to Navan and Properties to Neo4j — each maps to any object or custom field on the other side.
Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Labels Node type markers used to map source tables or objects onto the graph. Connect Transactions is specific to Navan and Labels to Neo4j — each maps to any object or custom field on the other side.
Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Indexes & Constraints Uniqueness constraints and indexes that make MERGE-based upserts reliable and fast. Manual Transactions is specific to Navan and Indexes & Constraints to Neo4j — each maps to any object or custom field on the other side.
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. Databases Named databases in a single instance that scope multi-tenant or multi-domain syncs. Bookings is specific to Navan and Databases to Neo4j — each maps to any object or custom field on the other side.
Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. Users & Roles Security principals controlling what an integration credential can query or modify. Custom Fields is specific to Navan and Users & Roles to Neo4j — each maps to any object or custom field on the other side.
Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Nodes Entity records (customers, products, accounts) written from source systems as labeled nodes. Receipts is specific to Navan and Nodes to Neo4j — each maps to any object or custom field on the other side.

How changes propagate between Navan and Neo4j

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.

Navan Neo4j 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 Neo4j through its API, with automatic retries and rate-limit backoff.

Neo4j Navan Sub-second propagation

DetectionChanges in Neo4j are captured at the source via change data capture — no polling loop against its API. Neo4j Change Data Capture on Enterprise and Aura streams graph changes.

DeliveryEach detected change is written to Navan through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • 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 Navan and Neo4j connectors work

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.

Neo4j

Integration surface
Bolt binary protocol with Cypher via official drivers, plus an HTTP query API
Authentication
Username/password (basic auth); enterprise deployments add SSO options
Change detection
