Why teams connect MongoDB and Navan

Work with Navan's financial data straight from MongoDB: 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 Custom Fields, Receipts, Repayments, Fees, and Adjustments, Users from Navan into Views, Change streams, GridFS files, Databases in MongoDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against MongoDB, 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 Pull Bookings by date range into a database to reconcile travel reservations against Card Transactions and monitor travel-policy spend.
  • 02 Sync Users and department mappings from an HRIS into reporting tables so every transaction is attributed to a cost center and manager.
  • 03 Sync MongoDB collections with a CRM so customer documents written by the application appear as CRM records, and CRM edits flow back as document updates.
  • 04 Replicate operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.

Common sync patterns

Write back safely

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

React to financial events

Changes in Navan appear in MongoDB as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

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

What you can sync between MongoDB 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.

MongoDB objects Navan objects How this pairing syncs
Views Read-only aggregation-defined sources for filtered sync datasets. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Views is specific to MongoDB and Manual Transactions to Navan — each maps to any object or custom field on the other side.
Change streams The oplog-backed event feed that powers real-time change capture. 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. Change streams is specific to MongoDB and Bookings to Navan — each maps to any object or custom field on the other side.
GridFS files Chunked file storage whose metadata can be referenced by synced documents. Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. GridFS files is specific to MongoDB and Custom Fields to Navan — each maps to any object or custom field on the other side.
Databases Logical groupings of collections that scope a sync connection. Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Databases is specific to MongoDB and Receipts to Navan — each maps to any object or custom field on the other side.
Collections The table-like sync unit; each collection maps to a table or object in the paired system. Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Collections is specific to MongoDB and Repayments, Fees, and Adjustments to Navan — each maps to any object or custom field on the other side.
Documents BSON records created, updated, and deleted during syncs, keyed by _id. Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Documents is specific to MongoDB and Users to Navan — each maps to any object or custom field on the other side.

How changes propagate between MongoDB 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.

MongoDB Navan Sub-second propagation

DetectionChanges in MongoDB are captured at the source via change data capture — no polling loop against its API. MongoDB oplog and change streams (requires the database to run as a replica set — even single-node).

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

Navan MongoDB 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 applied to MongoDB as a row-level write, with types converted between the two schemas.

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 MongoDB and Navan connectors work

MongoDB

Integration surface
MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management
Authentication
Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required
Change detection
MongoDB oplog and change streams (requires the database to run as a replica set — even single-node); Stacksync leverages these built-in tools to track changes in real time
Capabilities

MongoDB setup guide

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.
