Why teams connect AWS Aurora MySQL and Navan

Work with Navan's financial data straight from AWS Aurora MySQL: 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 Bookings, Custom Fields, Receipts, Repayments, Fees, and Adjustments from Navan into Tables, Rows, Columns, Primary keys and indexes in AWS Aurora MySQL and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against AWS Aurora MySQL, 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 Sync a production Aurora cluster with an analytics database while filtering out sensitive columns.
  • 04 Let operations teams edit records in a spreadsheet-style tool with changes written back to Aurora safely.

Common sync patterns

Query finance data like any other data

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

Write back safely

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

What you can sync between AWS Aurora MySQL 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 MySQL objects Navan objects How this pairing syncs
Rows Inserted, updated, and deleted individually or in bulk during two-way 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. Rows is specific to AWS Aurora MySQL and Connect Transactions to Navan — each maps to any object or custom field on the other side.
Columns MySQL data types are mapped to the paired system's field types during schema setup. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Columns is specific to AWS Aurora MySQL and Manual Transactions to Navan — each maps to any object or custom field on the other side.
Primary keys and indexes Used to match rows across systems and keep incremental syncs efficient. 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. Primary keys and indexes is specific to AWS Aurora MySQL and Bookings to Navan — each maps to any object or custom field on the other side.
Views Can serve as read-only sync sources for derived or filtered datasets. 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 is specific to AWS Aurora MySQL and Custom Fields to Navan — each maps to any object or custom field on the other side.
Foreign keys Express relationships that syncs preserve when mapping to related objects elsewhere. Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Foreign keys is specific to AWS Aurora MySQL and Receipts to Navan — each maps to any object or custom field on the other side.
Stored procedures and triggers Existing database logic keeps firing on rows written by a sync. Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Stored procedures and triggers is specific to AWS Aurora MySQL 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 MySQL 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 MySQL Navan Sub-second propagation

DetectionChanges in AWS Aurora MySQL are captured at the source via change data capture — no polling loop against its API. Log-based CDC via the MySQL binary log (binlog), with polling on timestamp columns as a fallback.

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

Navan AWS Aurora MySQL 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 MySQL 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.
