Why teams connect Navan and Ramp

Keep the customer, invoice, and payment records that Navan and Ramp share consistent in real time, whether the two systems split your finance stack or one is replacing the other.

Two finance systems in one company usually means one of two setups. Either the systems divide the work, with one issuing invoices or serving a business unit while the other holds the books, or one is on its way out and both must stay accurate during the transition. In both cases, the customer, invoice, and payment records the two systems share start to drift the moment updates are keyed twice or moved by hand.

Stacksync syncs Repayments, Fees, and Adjustments, Users, Card Transactions, Connect Transactions in Navan with Vendors, Funds (Spend Controls), General Ledger Accounts, Transactions in Ramp bi-directionally and in real time. A record created or corrected in either system appears in the other within seconds, with field-level mapping and conflict resolution in place of CSV exports and nightly batch jobs.

That matters most at close. When both systems agree on who was billed, what was paid, and what is outstanding, reconciliation stops being a hunt for which copy of the truth is current.

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 Mirror Bills and their approval and payment state into an AP or ERP system, marking each one ready-to-sync then synced to keep both ledgers reconciled.
  • 04 Read Reimbursements into a finance database for cross-entity expense reporting and reconciliation without manual CSV exports.

Common sync patterns

Entity or business-unit roll-up

Where each system serves a different entity or unit, sync the shared records so group-level reporting starts from consistent data.

Where Navan issues invoices and Ramp holds the books

Invoices and payments recorded on the billing side land in the system of record automatically, so revenue is captured once and correctly.

Parallel run during a migration

When one system is replacing the other, keep both live and matching through the cutover, so no transaction falls between the last export and go-live.

What you can sync between Navan and Ramp

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 Ramp objects How this pairing syncs
Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Users Employee and cardholder records; invited, updated, and deactivated, commonly synced from an HRIS or identity provider. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Departments Org groupings for cost-center and GL allocation; pushed from an ERP/HRIS and referenced by cards and transactions. Repayments, Fees, and Adjustments is specific to Navan and Departments to Ramp — each maps to any object or custom field on the other side.
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. Reimbursements Out-of-pocket expense claims; read for reporting and marked ready-to-sync then synced to the ERP. Card Transactions is specific to Navan and Reimbursements to Ramp — each maps to any object or custom field on the other side.
Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Bills Accounts-payable bills; created, updated, approved, and paid, then posted ready-to-sync and synced to accounting. Connect Transactions is specific to Navan and Bills to Ramp — 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. Vendors Supplier records under the accounting namespace; uploaded and updated for AP matching and payments. Manual Transactions is specific to Navan and Vendors to Ramp — 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. Funds (Spend Controls) Spend controls governing card usage; read and created via the funds API to enforce budgets per user, department, or program. Bookings is specific to Navan and Funds (Spend Controls) to Ramp — each maps to any object or custom field on the other side.

How changes propagate between Navan and Ramp

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 Ramp 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 written to Ramp through its API, with automatic retries and rate-limit backoff.

Ramp Navan Sub-second propagation

DetectionRamp notifies Stacksync of record changes through webhook events. Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events.

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.
  • Ramp: 200 requests per 10-second rolling window per source IP; exceeding it returns 429 Too Many Requests, and requests running over 60 seconds return 504. Results use keyset pagination (follow the page.next URL / start cursor); higher limits can be requested from support.

How the Navan and Ramp 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.

Ramp

Integration surface
REST API (Developer API v1)
Authentication
OAuth 2.0: exchange client_id/client_secret (HTTP Basic) at api.ramp.com/developer/v1/token for scoped bearer tokens; client_credentials grant for server-to-server and authorization_code for user-delegated access; scopes follow resource:permission (e.g. transactions:read, bills:write, accounting:write).
Change detection
Signed webhooks (HMAC-SHA256 X-Ramp-Signature) for bill, transaction, reimbursement, vendor, and user events; otherwise poll incrementally (synced_after on transactions, from_created_at on bills) with keyset pagination, or read the audit-logs/events feed.
