Why teams connect Navan and OpenSearch

Work with Navan's financial data straight from OpenSearch: 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 Indexes, Documents, Index aliases, Index templates in OpenSearch and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against OpenSearch, 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 Sync product catalogs from an ERP or database into the indexes that back storefront search.
  • 04 Keep Postgres as the source of truth while mirroring rows to OpenSearch for full-text and vector queries.

Common sync patterns

Query finance data like any other data

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

Write back safely

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

What you can sync between Navan and OpenSearch

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 OpenSearch objects How this pairing syncs
Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Snapshots Backup artifacts, relevant when reseeding an index from a repository Manual Transactions is specific to Navan and Snapshots to OpenSearch — 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. Indexes The core container; synced records land in indexes with defined mappings Bookings is specific to Navan and Indexes to OpenSearch — 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. Documents JSON records written via the index and bulk APIs and read via search queries Custom Fields is specific to Navan and Documents to OpenSearch — 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. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills Receipts is specific to Navan and Index aliases to OpenSearch — each maps to any object or custom field on the other side.
Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Index templates Mapping and settings presets applied to new indexes a sync creates Repayments, Fees, and Adjustments is specific to Navan and Index templates to OpenSearch — each maps to any object or custom field on the other side.
Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Ingest pipelines Server-side processors that transform documents as they are written Users is specific to Navan and Ingest pipelines to OpenSearch — each maps to any object or custom field on the other side.

How changes propagate between Navan and OpenSearch

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

OpenSearch Navan Interval-based propagation

DetectionStacksync polls OpenSearch for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.

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.
  • OpenSearch: Throughput bounded by cluster sizing rather than fixed API quotas.

How the Navan and OpenSearch 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

OpenSearch

Integration surface
