Why teams connect Navan and Oracle DB

Work with Navan's financial data straight from Oracle DB: 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 Users, Card Transactions, Connect Transactions, Manual Transactions from Navan into PL/SQL procedures and packages, Partitions, JSON columns, Tables in Oracle DB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Oracle DB, 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 Write changes from SaaS apps back into Oracle so PL/SQL jobs and reports run on current data.
  • 04 Log-based replication of order and inventory tables into an analytics warehouse instead of nightly batch dumps.

Common sync patterns

Write back safely

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

React to financial events

Changes in Navan appear in Oracle DB 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 Oracle DB as regular tables or collections your team can join, index, and query.

What you can sync between Navan and Oracle DB

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 Oracle DB objects How this pairing syncs
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. Views Curated read-only projections exposed to downstream consumers Bookings is specific to Navan and Views to Oracle DB — 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. Materialized views Precomputed results occasionally used as stable replication sources Custom Fields is specific to Navan and Materialized views to Oracle DB — 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. Schemas Per-user namespaces that scope sync permissions and object visibility Receipts is specific to Navan and Schemas to Oracle DB — 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. Sequences Key generators to respect when external systems insert rows Repayments, Fees, and Adjustments is specific to Navan and Sequences to Oracle DB — 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. PL/SQL procedures and packages In-database logic that can consume or transform synced data Users is specific to Navan and PL/SQL procedures and packages to Oracle DB — each maps to any object or custom field on the other side.
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. Partitions Physical subdivisions relevant when replicating high-volume tables Card Transactions is specific to Navan and Partitions to Oracle DB — each maps to any object or custom field on the other side.

How changes propagate between Navan and Oracle DB

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 Oracle DB 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 Oracle DB as a row-level write, with types converted between the two schemas.

Oracle DB Navan Sub-second propagation

DetectionChanges in Oracle DB are captured at the source via change data capture — no polling loop against its API. Log-based CDC from redo logs via LogMiner or GoldenGate, or trigger and timestamp polling.

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.
  • Oracle DB: Throughput bounded by database resources rather than API quotas.

How the Navan and Oracle DB 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.

Oracle DB

Integration surface
SQL wire protocol (Oracle Net) via JDBC, ODBC, and native OCI drivers
