Why teams connect Navan and Render Postgres

Work with Navan's financial data straight from Render Postgres: 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 Manual Transactions, Bookings, Custom Fields, Receipts from Navan into Views, Materialized Views, Schemas, Columns and Types in Render Postgres and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Render Postgres, 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 Serve as the operational read/write store behind internal tools while Stacksync keeps it consistent with SaaS systems of record.
  • 04 Replicate between a Render database and another Postgres or warehouse for migration or environment separation.

Common sync patterns

Write back safely

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

React to financial events

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

What you can sync between Navan and Render Postgres

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 Render Postgres objects How this pairing syncs
Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Columns and Types Full Postgres type system including JSONB and arrays; field mappings preserve native types instead of flattening to strings. Connect Transactions is specific to Navan and Columns and Types to Render Postgres — each maps to any object or custom field on the other side.
Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Indexes and Constraints Primary keys, unique constraints, and foreign keys; unique keys drive idempotent upserts and conflict resolution during sync. Manual Transactions is specific to Navan and Indexes and Constraints to Render Postgres — 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. Tables Relational tables with full column typing; synced two-way with CRMs, ERPs, and SaaS apps so application data is queryable as plain Postgres rows. Bookings is specific to Navan and Tables to Render Postgres — 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. Views Saved queries exposed as read-only relations; read out to BI tools or downstream syncs without duplicating transformation logic. Custom Fields is specific to Navan and Views to Render Postgres — 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. Materialized Views Precomputed query results refreshed on demand; read for fast reporting tables that downstream systems can consume. Receipts is specific to Navan and Materialized Views to Render Postgres — 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. Schemas Namespaces that organize tables per app or environment; sync targets are scoped per schema to keep synced data isolated and tidy. Repayments, Fees, and Adjustments is specific to Navan and Schemas to Render Postgres — each maps to any object or custom field on the other side.

How changes propagate between Navan and Render Postgres

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

Render Postgres Navan Sub-second propagation

DetectionChanges in Render Postgres are captured at the source via change data capture — no polling loop against its API. Logical replication via WAL and replication slots for change data capture when enabled on the instance, with timestamp or cursor-based polling as the.

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.
  • Render Postgres: No API rate limits — throughput is bounded by the instance's plan (CPU, RAM, connection limit); connection pooling is recommended since managed plans cap concurrent connections.

How the Navan and Render Postgres 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
read · write · webhooks
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.

Render Postgres

Integration surface
PostgreSQL wire protocol (managed Postgres on Render)
Authentication
Standard Postgres connection string — host, port, database, user, password with TLS; Render provides internal and external connection URLs and IP allowlisting
Change detection
Logical replication via WAL and replication slots for change data capture when enabled on the instance, with timestamp or cursor-based polling as the fallback
Capabilities

Rate limits
No API rate limits — throughput is bounded by the instance's plan (CPU, RAM, connection limit); connection pooling is recommended since managed plans cap concurrent connections.
