Why teams connect Couchbase and Navan

Work with Navan's financial data straight from Couchbase: 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 Bookings, Custom Fields, Receipts, Repayments, Fees, and Adjustments from Navan into JSON Documents, Global Secondary Indexes, XDCR replications, Full-text search indexes in Couchbase and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Couchbase, 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 Push coded expense transactions into an accounting system, then set their ERP sync status in Navan so the same records are not exported twice.
  • 02 Pull Bookings by date range into a database to reconcile travel reservations against Card Transactions and monitor travel-policy spend.
  • 03 Stream document mutations via DCP into downstream systems so caches, search indexes, or warehouses stay current.
  • 04 Two-way sync between Couchbase (serving application data) and a CRM so support and sales teams see live application state.

Common sync patterns

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between Couchbase 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.

Couchbase objects Navan objects How this pairing syncs
Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. 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 Couchbase and Repayments, Fees, and Adjustments to Navan — each maps to any object or custom field on the other side.
JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. JSON Documents is specific to Couchbase and Users to Navan — each maps to any object or custom field on the other side.
Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. 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. Global Secondary Indexes is specific to Couchbase and Card Transactions to Navan — each maps to any object or custom field on the other side.
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. XDCR replications is specific to Couchbase and Connect Transactions to Navan — each maps to any object or custom field on the other side.
Full-text search indexes Search indexes over documents, relevant when syncing searchable content. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Full-text search indexes is specific to Couchbase and Manual Transactions to Navan — each maps to any object or custom field on the other side.
Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. 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. Buckets is specific to Couchbase and Bookings to Navan — each maps to any object or custom field on the other side.

How changes propagate between Couchbase 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.

Couchbase Navan Sub-second propagation

DetectionChanges in Couchbase are captured at the source via change data capture — no polling loop against its API. Database Change Protocol (DCP) streams document mutations.

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

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

Rate-limit considerations

  • Couchbase: Throughput is bounded by cluster sizing rather than API rate 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 Couchbase and Navan connectors work

Couchbase

Integration surface
SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs
Authentication
Database credentials with role-based access control, typically over TLS
Change detection
Database Change Protocol (DCP) streams document mutations; SQL++ polling on document fields as an alternative
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by cluster sizing rather than API rate 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.
