Why teams connect Navan and VoltDB

Work with Navan's financial data straight from VoltDB: 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 Streams, Export Targets and Topics, Partitioned Tables, Replicated Tables in VoltDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against VoltDB, 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 customer or account reference data from a CRM into VoltDB replicated tables for in-transaction lookups such as fraud or policy checks.
  • 04 Stream committed VoltDB results out through export targets into a warehouse for historical analysis.

Common sync patterns

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between Navan and VoltDB

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 VoltDB objects How this pairing syncs
Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. Streams Insert-only constructs that feed the export subsystem with committed rows. Custom Fields is specific to Navan and Streams to VoltDB — 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. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. Receipts is specific to Navan and Export Targets and Topics to VoltDB — 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. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. Repayments, Fees, and Adjustments is specific to Navan and Partitioned Tables to VoltDB — 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. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. Users is specific to Navan and Replicated Tables to VoltDB — 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. Stored Procedures Precompiled transactional units that serve as the primary write interface. Card Transactions is specific to Navan and Stored Procedures to VoltDB — each maps to any object or custom field on the other side.
Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. Connect Transactions is specific to Navan and Materialized Views to VoltDB — each maps to any object or custom field on the other side.

How changes propagate between Navan and VoltDB

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

VoltDB Navan Interval-based propagation

DetectionStacksync polls VoltDB for changes on an incremental schedule, reading only records changed since the previous pass. Export streams and topics push committed changes to configured targets.

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.
  • VoltDB: No API rate limits; throughput is bounded by partition count and cluster sizing.

How the Navan and VoltDB 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.
