Why teams connect Elasticsearch and Navan

Work with Navan's financial data straight from Elasticsearch: 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 Connect Transactions, Manual Transactions, Bookings, Custom Fields from Navan into Aliases, Data streams, Ingest pipelines, Index templates in Elasticsearch and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Elasticsearch, 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 Card Transactions and Manual Transactions into Postgres or a warehouse so finance analyzes corporate spend in SQL without manual CSV exports.
  • 02 Push coded expense transactions into an accounting system, then set their ERP sync status in Navan so the same records are not exported twice.
  • 03 Sync CRM accounts and contacts into an Elasticsearch index to power internal search across customer records.
  • 04 Push product catalog data from an ERP or commerce database into Elasticsearch for storefront search.

Common sync patterns

Query finance data like any other data

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

Write back safely

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

What you can sync between Elasticsearch 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.

Elasticsearch objects Navan objects How this pairing syncs
Index templates Reusable settings and mappings applied automatically to new indices a sync creates. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Index templates is specific to Elasticsearch and Manual Transactions to Navan — each maps to any object or custom field on the other side.
Indices Target containers for synced records; each holds a table-like collection of JSON documents. 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. Indices is specific to Elasticsearch and Bookings to Navan — each maps to any object or custom field on the other side.
Documents The unit of sync; JSON records created, updated, and deleted by _id. 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 is specific to Elasticsearch and Custom Fields to Navan — each maps to any object or custom field on the other side.
Index mappings Field type definitions that determine how synced fields are indexed and queried. Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Index mappings is specific to Elasticsearch and Receipts to Navan — each maps to any object or custom field on the other side.
Aliases Stable read/write names that let a sync cut over between index versions without downtime. Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Aliases is specific to Elasticsearch and Repayments, Fees, and Adjustments to Navan — each maps to any object or custom field on the other side.
Data streams Append-only targets for time-series or event data pushed from source systems. Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Data streams is specific to Elasticsearch and Users to Navan — each maps to any object or custom field on the other side.

How changes propagate between Elasticsearch 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.

Elasticsearch Navan Interval-based propagation

DetectionStacksync polls Elasticsearch for changes on an incremental schedule, reading only records changed since the previous pass. Polling on timestamp or sequence fields.

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

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

Rate-limit considerations

  • Elasticsearch: No fixed request quota; throughput is bounded by cluster sizing, thread pools, and bulk queue capacity.
  • 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 Elasticsearch and Navan connectors work

Elasticsearch

Integration surface
REST API (JSON over HTTP)
Authentication
API keys or basic authentication; Elastic Cloud also issues service account tokens
Change detection
Polling on timestamp or sequence fields; Elasticsearch does not expose a native change feed or webhooks
Capabilities

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.
