Why teams connect IBM Db2 and Navan

Work with Navan's financial data straight from IBM Db2: 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 Databases, Schemas, Tables, Views in IBM Db2 and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against IBM Db2, 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 Feed changes captured from Db2 logs into downstream event pipelines.
  • 04 Expose Db2 records that back core business systems to a CRM so sales and support see order or account state.

Common sync patterns

Query finance data like any other data

Customers, invoices, and payments from Navan live in IBM Db2 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 IBM Db2; Stacksync handles the API calls, rate limits, and retries against Navan.

Write back safely

Updates written to the synced tables in IBM Db2 propagate into Navan, so automations can create or correct finance records without custom integration code.

What you can sync between IBM Db2 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.

IBM Db2 objects Navan objects How this pairing syncs
Indexes Support fast key lookups on sync match columns. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Indexes is specific to IBM Db2 and Manual Transactions to Navan — each maps to any object or custom field on the other side.
Stored Procedures Existing business logic sometimes invoked as part of write paths. 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. Stored Procedures is specific to IBM Db2 and Bookings to Navan — each maps to any object or custom field on the other side.
Sequences ID generation relevant when external systems insert rows. Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. Sequences is specific to IBM Db2 and Custom Fields to Navan — each maps to any object or custom field on the other side.
Tablespaces Physical storage layout that operators consider when adding synced tables. Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Tablespaces is specific to IBM Db2 and Receipts to Navan — each maps to any object or custom field on the other side.
Databases The connection target; each database holds the schemas a sync addresses. Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Databases is specific to IBM Db2 and Repayments, Fees, and Adjustments to Navan — each maps to any object or custom field on the other side.
Schemas Namespaces separating synced data from application and system objects. Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Schemas is specific to IBM Db2 and Users to Navan — each maps to any object or custom field on the other side.

How changes propagate between IBM Db2 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.

IBM Db2 Navan Sub-second propagation

DetectionChanges in IBM Db2 are captured at the source via change data capture — no polling loop against its API. Log-based CDC through IBM's replication tooling where licensed.

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

Navan IBM Db2 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 IBM Db2 as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • IBM Db2: No API rate limits; throughput is bounded by instance resources and workload management settings.
  • 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 IBM Db2 and Navan connectors work

IBM Db2

Integration surface
SQL via JDBC/ODBC/CLI drivers; optional REST endpoints in some editions
Authentication
Database credentials, typically backed by OS or LDAP authentication
Change detection
Log-based CDC through IBM's replication tooling where licensed; otherwise polling on timestamp or audit columns
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by instance resources and workload management settings

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.
