Why teams connect Easypost and SAP S/4HANA

Keep the storefront in step with the back office: Easypost and SAP S/4HANA share products, inventory, and orders in real time, in both directions.

Easypost runs the storefront and takes the orders; SAP S/4HANA 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 Parcel, Rate, Tracker, Batch in Easypost with Journal Entries, Customer / Supplier Roles, Production Orders, Business Partners in SAP S/4HANA field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from SAP S/4HANA, 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 Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
  • 04 Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.

Common sync patterns

Fulfillment and shipment status close the loop

As orders are picked, shipped, or invoiced in SAP S/4HANA, 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 SAP S/4HANA is the inventory system of record: stock stays accurate

Available quantities from SAP S/4HANA publish to Easypost, so the store shows what can actually ship and stops overselling.

What you can sync between Easypost and SAP S/4HANA

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 SAP S/4HANA objects How this pairing syncs
CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Journal Entries Financial postings read into warehouses and consolidation tools for reporting. CarrierAccount is specific to Easypost and Journal Entries to SAP S/4HANA — 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. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. Webhook is specific to Easypost and Customer / Supplier Roles to SAP S/4HANA — 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. Production Orders Manufacturing order status surfaced in planning and operations tools. Shipment is specific to Easypost and Production Orders to SAP S/4HANA — 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. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. Address is specific to Easypost and Business Partners to SAP S/4HANA — 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. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. Parcel is specific to Easypost and Sales Orders to SAP S/4HANA — 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. Purchase Orders Procurement documents shared with supplier portals and spend-management tools. Rate is specific to Easypost and Purchase Orders to SAP S/4HANA — each maps to any object or custom field on the other side.

How changes propagate between Easypost and SAP S/4HANA

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 SAP S/4HANA 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 SAP S/4HANA through its API, with automatic retries and rate-limit backoff.

SAP S/4HANA Easypost Interval-based propagation

DetectionStacksync polls SAP S/4HANA for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change timestamps exposed by the OData services.

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.
  • SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.
