Why teams connect Easypost and IBM AS/400

Give your engineers Easypost's products, orders, and customers in IBM AS/400: read them with normal queries, write inventory and prices back through the sync, and skip the storefront API.

E-commerce data sits behind an API built for the storefront, not for your internal systems. Teams that need those records, for order routing, inventory logic, reporting, or back-office tools, end up writing integration code against a rate-limited API and maintaining it through every catalog change and platform upgrade.

Stacksync mirrors CarrierAccount, Webhook, Shipment, Address from Easypost into IBM AS/400 and keeps both sides consistent in real time. Whatever Easypost holds, whether products, orders, customers, or inventory, those records become rows your code can query, and changes written in IBM AS/400, such as new prices, stock levels, or fulfillment status, sync back into Easypost with its validations respected.

Merchandising and operations keep working in the storefront, engineers keep working in the database, and neither side has to reconcile against a nightly export.

Common use cases

  • 01 Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • 02 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • 03 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.
  • 04 Pull Shipment, Rate, and Refund records into a warehouse to report shipping cost per carrier and service and reclaim postage on labels that were never scanned.

Common sync patterns

Controlled write-back

Choose exactly which tables and fields may flow from IBM AS/400 back into Easypost, keeping the store authoritative on what it owns.

Read the store's data with a query

Records from Easypost, whether products, orders, customers, or inventory, live in IBM AS/400 as ordinary tables or collections, joinable with the rest of your data.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Easypost API, rate limits, and retries.

What you can sync between Easypost and IBM AS/400

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 IBM AS/400 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. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Webhook is specific to Easypost and Data queues to IBM AS/400 — 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. Libraries The schema-equivalent containers that scope which files a sync reads. Shipment is specific to Easypost and Libraries to IBM AS/400 — 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. Physical files (tables) The Db2 for i tables mapped directly to sync targets. Address is specific to Easypost and Physical files (tables) to IBM AS/400 — 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. Logical files (views) Indexed or filtered views over physical files, usable as read sources. Parcel is specific to Easypost and Logical files (views) to IBM AS/400 — 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. Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Rate is specific to Easypost and Members to IBM AS/400 — 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. Rows / records The unit of read and write, accessed via SQL or record-level access. Tracker is specific to Easypost and Rows / records to IBM AS/400 — each maps to any object or custom field on the other side.

How changes propagate between Easypost and IBM AS/400

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 IBM AS/400 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 applied to IBM AS/400 as a row-level write, with types converted between the two schemas.

IBM AS/400 Easypost Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

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.
  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
