Why teams connect Easypost and Infor WMS

Keep the storefront in step with the back office: Easypost and Infor WMS share products, inventory, and orders in real time, in both directions.

Easypost runs the storefront and takes the orders; Infor WMS 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 Tracker, Batch, CarrierAccount, Webhook in Easypost with Waves, Tasks, Locations, Shipments in Infor WMS field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Infor WMS, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 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.
  • 02 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.
  • 03 Sync inventory positions from Infor WMS to an OMS or e-commerce platform so promised stock reflects the warehouse
  • 04 Push sales orders from an ERP into the WMS for wave planning and picking, then return status updates

Common sync patterns

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in Infor WMS, tracking and status flow back to Easypost so buyers see accurate updates.

One customer master

Where both systems keep customer records, a correction in either propagates to the other, ending dual maintenance.

Where Infor WMS is the inventory system of record: stock stays accurate

Available quantities from Infor WMS publish to Easypost, so the store shows what can actually ship and stops overselling.

What you can sync between Easypost and Infor WMS

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 Infor WMS objects How this pairing 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. Shipments Ship confirmations and tracking references flow back to the order source system. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
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. Shipment Orders Outbound orders arrive from the ERP or OMS for allocation and picking. Tracker is specific to Easypost and Shipment Orders to Infor WMS — each maps to any object or custom field on the other side.
Batch Bulk shipment processing; create a batch, add or remove shipments, buy all labels at once, and generate a consolidated label or ScanForm for the day's orders. Waves Wave assignments group orders for fulfillment and can be reported outward. Batch is specific to Easypost and Waves to Infor WMS — each maps to any object or custom field on the other side.
CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Tasks Warehouse task data supports labor and productivity reporting in BI tools. CarrierAccount is specific to Easypost and Tasks to Infor WMS — each maps to any object or custom field on the other side.
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. Locations Bin and zone definitions scope inventory records during mapping. Webhook is specific to Easypost and Locations to Infor WMS — 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. Appointments Dock appointment data coordinates carriers and yard operations with external schedules. Address is specific to Easypost and Appointments to Infor WMS — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Infor WMS

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 Infor WMS 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 Infor WMS through its API, with automatic retries and rate-limit backoff.

Infor WMS Easypost Sub-second propagation

DetectionInfor WMS notifies Stacksync of record changes through webhook events. ION event publishing or scheduled polling of API endpoints.

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.
  • Infor WMS: Subject to Infor ION API gateway throttling policies.
