Why teams connect Dynamics 365 F&O and Easypost

Keep the storefront in step with the back office: Easypost and Dynamics 365 F&O share products, inventory, and orders in real time, in both directions.

Easypost runs the storefront and takes the orders; Dynamics 365 F&O owns the item master, the stock on hand, and the finance behind every transaction. The two overlap wherever the same products, customers, and sales matter to both — and when re-keying or an overnight batch is what connects them, the store oversells items it can't ship, quotes prices finance never set, or leaves buyers waiting on status that already changed.

Stacksync syncs Webhook, Shipment, Address, Parcel in Easypost with On-hand Inventory, Customers, Vendors, Released Products in Dynamics 365 F&O field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Dynamics 365 F&O, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Batch-create and buy labels for a day's orders, generate a ScanForm, and write each label and tracking code back into the fulfillment system.
  • 02 When an order is ready to ship in an OMS, ERP, or database, create an EasyPost Shipment, buy the lowest qualifying Rate, and write the label URL and tracking code back onto the order.
  • 03 Distribute product and price master data from F&O to downstream channels through a synced database.
  • 04 Sync customers, vendors, and released products into an operational database that internal apps read instead of calling OData directly.

Common sync patterns

Where Dynamics 365 F&O is the inventory system of record: stock stays accurate

Available quantities from Dynamics 365 F&O publish to Easypost, so the store shows what can actually ship and stops overselling.

New orders reach the back office

An order captured in Easypost creates the matching record in Dynamics 365 F&O with customer, line items, and totals, so fulfillment and invoicing start without re-entry.

One product catalog

Where both systems keep item records, SKUs, descriptions, and attributes stay aligned so the store and the back office describe the same product.

What you can sync between Dynamics 365 F&O and Easypost

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.

Dynamics 365 F&O objects Easypost objects How this pairing syncs
On-hand Inventory Stock positions; read out to storefronts and internal apps for availability. 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. On-hand Inventory is specific to Dynamics 365 F&O and Webhook to Easypost — each maps to any object or custom field on the other side.
Customers Customer master records; kept aligned with CRM accounts in two-way syncs. 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. Customers is specific to Dynamics 365 F&O and Shipment to Easypost — each maps to any object or custom field on the other side.
Vendors Supplier master records; synced with procurement and AP tools. 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. Vendors is specific to Dynamics 365 F&O and Address to Easypost — each maps to any object or custom field on the other side.
Released Products Sellable product master; read out to commerce channels and CRM catalogs. Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Released Products is specific to Dynamics 365 F&O and Parcel to Easypost — each maps to any object or custom field on the other side.
Sales Orders Order transactions; written in from storefronts or CRM and tracked through fulfillment. 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. Sales Orders is specific to Dynamics 365 F&O and Rate to Easypost — each maps to any object or custom field on the other side.
Purchase Orders Procurement transactions; extracted for spend and supply chain reporting. 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. Purchase Orders is specific to Dynamics 365 F&O and Tracker to Easypost — each maps to any object or custom field on the other side.

How changes propagate between Dynamics 365 F&O and Easypost

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.

Dynamics 365 F&O Easypost Sub-second propagation

DetectionDynamics 365 F&O pushes changes as they happen — webhook events backed by change data capture. Change data capture via the Dynamics 365 Change Tracking feature, enabled per entity.

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

DeliveryEach detected change is written to Dynamics 365 F&O through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Dynamics 365 F&O: OData requests are subject to platform throttling; high-volume loads belong in the Data Management Framework.
  • 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.
