Why teams connect AWS Aurora PostgreSQL and Navan

Work with Navan's financial data straight from AWS Aurora PostgreSQL: 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 Views and materialized views, Foreign keys, Replication slots and publications, Databases and schemas in AWS Aurora PostgreSQL and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against AWS Aurora PostgreSQL, 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 Feed operational dashboards from a read replica while the writer handles sync traffic.
  • 04 Expose ERP records such as customers, orders, and invoices as Postgres tables the engineering team can query and update with plain SQL.

Common sync patterns

Write back safely

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

React to financial events

Changes in Navan appear in AWS Aurora PostgreSQL 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 AWS Aurora PostgreSQL as regular tables or collections your team can join, index, and query.

What you can sync between AWS Aurora PostgreSQL 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.

AWS Aurora PostgreSQL objects Navan objects How this pairing syncs
Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. 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 is specific to AWS Aurora PostgreSQL and Connect Transactions to Navan — each maps to any object or custom field on the other side.
Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Primary keys and constraints is specific to AWS Aurora PostgreSQL and Manual Transactions to Navan — each maps to any object or custom field on the other side.
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. 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 and materialized views is specific to AWS Aurora PostgreSQL and Bookings to Navan — each maps to any object or custom field on the other side.
Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. Foreign keys is specific to AWS Aurora PostgreSQL and Custom Fields to Navan — each maps to any object or custom field on the other side.
Replication slots and publications The logical replication objects that power log-based CDC. Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Replication slots and publications is specific to AWS Aurora PostgreSQL and Receipts to Navan — each maps to any object or custom field on the other side.
Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Databases and schemas is specific to AWS Aurora PostgreSQL and Repayments, Fees, and Adjustments to Navan — each maps to any object or custom field on the other side.

How changes propagate between AWS Aurora PostgreSQL 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.

AWS Aurora PostgreSQL Navan Sub-second propagation

DetectionChanges in AWS Aurora PostgreSQL are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication (WAL decoding through replication slots), with timestamp polling as a fallback.

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

Navan AWS Aurora PostgreSQL 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 AWS Aurora PostgreSQL as a row-level write, with types converted between the two schemas.

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.
