Why teams connect Easypost and Infor LN

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

Easypost runs the storefront and takes the orders; Infor LN 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 Purchase orders, Production orders, Warehouse / inventory, Projects in Infor LN field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Infor LN, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 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.
  • 02 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.
  • 03 Flow EDI and ecommerce sales orders into LN and return order status and shipment confirmations.
  • 04 Replicate LN data into a warehouse for production, OTIF, and supply chain reporting.

Common sync patterns

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.

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in Infor LN, 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.

What you can sync between Easypost and Infor LN

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 LN 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. Bills of material Product structures shared with engineering and planning tools. Webhook is specific to Easypost and Bills of material to Infor LN — 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. Business partners LN's unified customer/supplier records matched against CRM accounts. Shipment is specific to Easypost and Business partners to Infor LN — 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. Sales orders Demand documents synced in from EDI and commerce channels. Address is specific to Easypost and Sales orders to Infor LN — 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. Purchase orders Supply documents shared with supplier and procurement systems. Parcel is specific to Easypost and Purchase orders to Infor LN — 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. Production orders Shop-floor work orders synced with MES for execution visibility. Rate is specific to Easypost and Production orders to Infor LN — 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. Warehouse / inventory Stock positions exposed so external channels reflect real availability. Tracker is specific to Easypost and Warehouse / inventory to Infor LN — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Infor LN

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

Infor LN Easypost Interval-based propagation

DetectionStacksync polls Infor LN for changes on an incremental schedule, reading only records changed since the previous pass. Event-style BOD publications through Infor ION where configured.

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 LN: Subject to the ION API gateway's tenant rate limits in cloud deployments.
