Why teams connect Easypost and Navan
Turn every Easypost order into clean revenue: Navan and Easypost keep customers, orders, and payment status aligned in real time, in both directions.
Easypost runs the storefront — the catalog, the orders, and the buyers placing them. Navan records the money behind those orders — invoices, revenue, payments, and the ledger the business closes on. The overlap is every customer, order, and product both sides need to agree on, and when that overlap is bridged by CSV export or an overnight batch, finance reconciles against stale numbers while the store quotes prices or stock the books no longer recognize.
Stacksync syncs Repayments, Fees, and Adjustments, Users, Card Transactions, Connect Transactions in Navan with Webhook, Shipment, Address, Parcel in Easypost field by field, in real time, and in both directions. You decide which system owns which fields — an order's totals from Easypost, its paid-or-overdue state from Navan — and Stacksync keeps every copy consistent and resolves conflicts by the rules you set.
The result is one shared record of who bought what and whether it has been paid, so the storefront, support, and the finance team all read from the same current data instead of re-keying it between systems.
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 Create a Tracker for every outbound shipment and stream tracker.updated webhook events into Postgres or a warehouse so support and ops see live delivery status beside order records.
- 04 Verify and normalize customer Addresses through EasyPost before they are saved to the CRM or OMS to cut failed deliveries and carrier address-correction surcharges.
Common sync patterns
Where Navan is the money system of record: payment status on the order
Paid, overdue, and refunded state from Navan lands on the order or account in Easypost, so the store and support see what has actually been collected.
One customer master
Where both systems keep customer or buyer records, an edit in either propagates to the other, ending duplicate accounts and mismatched contact details.
Catalog and pricing stay aligned
Products, SKUs, and prices maintained on one side propagate to the other, so what the store sells and what the ledger books stay in step.
What you can sync between Easypost 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.
| Easypost objects | Navan objects | How this pairing syncs | |
|---|---|---|---|
| Webhook Event subscriptions delivering an Event via HTTP POST on object changes; full CRUD (create, retrieve, list, update, delete) and the mechanism for near-real-time change delivery to Stacksync. | 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. | Webhook is specific to Easypost and Bookings to Navan — each maps to any object or custom field on the other side. | |
| Shipment The central writable object: create with a to/from Address and Parcel, receive Rate options, then buy a label to get postage_label and tracking_code; retrieve and list with cursor pagination. | Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. | Shipment is specific to Easypost and Custom Fields to Navan — each maps to any object or custom field on the other side. | |
| Address Origin and destination locations; create, retrieve, and list, plus address verification (delivery and residential) to normalize and validate addresses before they are saved downstream. | Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. | Address is specific to Easypost and Receipts to Navan — each maps to any object or custom field on the other side. | |
| Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. | Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. | Parcel is specific to Easypost and Repayments, Fees, and Adjustments to Navan — each maps to any object or custom field on the other side. | |
| Rate Carrier service and price options EasyPost generates on a Shipment; read-only - you select a rate id and buy it, you do not create or edit rates directly. | Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. | Rate is specific to Easypost and Users to Navan — each maps to any object or custom field on the other side. | |
| Tracker Tracking for a shipment by tracking_code and carrier; create a Tracker to begin tracking, read status and tracking_details, and receive tracker.updated events via webhook as the parcel moves. | 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. | Tracker is specific to Easypost and Card Transactions to Navan — each maps to any object or custom field on the other side. |
How changes propagate between Easypost 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.
Easypost Navan Sub-second propagation
DetectionEasypost notifies Stacksync of record changes through webhook events. Webhooks deliver an Event via HTTP POST on object changes (e.g.
DeliveryEach detected change is written to Navan through its API, with automatic retries and rate-limit backoff.
Navan Easypost 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 Easypost through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Easypost: Fixed 5 requests/second on index (list) endpoints plus a dynamic load-based limiter protecting buy and rate operations; exceeding either returns HTTP 429 Too Many Requests.
- 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 Easypost and Navan connectors work
Easypost
- Integration surface
- REST API (EasyPost API v2, https://api.easypost.com/v2)
- Authentication
- HTTP Basic auth with the API key as the username and an empty password (Bearer token also accepted); separate Test and Production keys
- Change detection
- Webhooks deliver an Event via HTTP POST on object changes (e.g. tracker.updated); historical pulls via list/index endpoints using before_id/after_id cursor pagination

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.
