Why teams connect Google AlloyDB and Navan

Work with Navan's financial data straight from Google AlloyDB: 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 Sequences, Replication Slots, Databases, Schemas in Google AlloyDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Google AlloyDB, 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 Use logical replication to feed AlloyDB changes into warehouses or event pipelines without batch jobs.
  • 04 Consolidate SaaS data into AlloyDB and serve analytics from its columnar engine without a separate OLAP store.

Common sync patterns

React to financial events

Changes in Navan appear in Google AlloyDB 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 Google AlloyDB 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 Google AlloyDB; Stacksync handles the API calls, rate limits, and retries against Navan.

What you can sync between Google AlloyDB 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.

Google AlloyDB objects Navan objects How this pairing syncs
Schemas Namespaces used to separate synced SaaS data from application tables. 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. Schemas is specific to Google AlloyDB and Card Transactions to Navan — each maps to any object or custom field on the other side.
Tables Primary read/write target for bi-directional sync with CRMs and other systems. Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Tables is specific to Google AlloyDB and Connect Transactions to Navan — each maps to any object or custom field on the other side.
Views Curated projections used as read-only sync sources. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Views is specific to Google AlloyDB and Manual Transactions to Navan — each maps to any object or custom field on the other side.
Materialized Views Precomputed aggregates refreshed and synced outward on a schedule. 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. Materialized Views is specific to Google AlloyDB and Bookings to Navan — each maps to any object or custom field on the other side.
Indexes Keep sync key lookups fast on high-volume tables. Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. Indexes is specific to Google AlloyDB and Custom Fields to Navan — each maps to any object or custom field on the other side.
Sequences ID generation relevant when external systems insert rows. Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Sequences is specific to Google AlloyDB and Receipts to Navan — each maps to any object or custom field on the other side.

How changes propagate between Google AlloyDB 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.

Google AlloyDB Navan Sub-second propagation

DetectionChanges in Google AlloyDB are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication.

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

Navan Google AlloyDB 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 Google AlloyDB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Google AlloyDB: No API-style rate limits; throughput is bounded by instance size.
  • 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.

How the Google AlloyDB and Navan connectors work

Google AlloyDB

Integration surface
SQL wire protocol (PostgreSQL-compatible), with connectivity through the AlloyDB Auth Proxy or private IP
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC via PostgreSQL logical replication; polling on timestamp columns as a fallback
Capabilities

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.
