Why teams connect Easypost and SAP

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

Easypost runs the storefront and takes the orders; SAP 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 CarrierAccount, Webhook, Shipment, Address in Easypost with Billing Documents, GL Accounts and Journal Entries, Production Orders, Inventory / Stock in SAP field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from SAP, 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 Keep MES and WMS systems aligned with production orders and goods movements.
  • 04 Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.

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 SAP, 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 SAP

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 objects How this pairing syncs
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. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Tracker is specific to Easypost and Inventory / Stock to SAP — 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. Cost Centers Controlling masters read for mapping costs in finance integrations. Batch is specific to Easypost and Cost Centers to SAP — 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. Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. CarrierAccount is specific to Easypost and Business Partners to SAP — 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. Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. Webhook is specific to Easypost and Materials (Products) to SAP — 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. Sales Orders Order documents written from external channels and read for status and fulfillment. Shipment is specific to Easypost and Sales Orders to SAP — 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. Purchase Orders Procurement documents synced with supplier portals and spend tools. Address is specific to Easypost and Purchase Orders to SAP — each maps to any object or custom field on the other side.

How changes propagate between Easypost and SAP

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

SAP Easypost Sub-second propagation

DetectionSAP notifies Stacksync of record changes through webhook events. Business events via SAP Event Mesh on S/4HANA.

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: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
