Why teams connect Easypost and InterSystems IRIS

Give your engineers Easypost's products, orders, and customers in InterSystems IRIS: 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 Batch, CarrierAccount, Webhook, Shipment from Easypost into InterSystems IRIS 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 InterSystems IRIS, 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 Replicate IRIS tables to Postgres so application teams can build against a familiar database
  • 02 Sync operational tables in IRIS bi-directionally with a CRM so business teams work on IRIS-backed data without SQL access
  • 03 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.
  • 04 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.

Common sync patterns

Read the store's data with a query

Records from Easypost, whether products, orders, customers, or inventory, live in InterSystems IRIS 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.

React to store changes

Updates in Easypost arrive as row changes in InterSystems IRIS, so jobs and triggers can respond the moment an order, price, or stock level changes.

What you can sync between Easypost and InterSystems IRIS

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 InterSystems IRIS objects How this pairing syncs
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. Views SQL views expose curated slices of data for outbound replication. Batch is specific to Easypost and Views to InterSystems IRIS — 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. Schemas Schema organization scopes which tables a sync connection can see. CarrierAccount is specific to Easypost and Schemas to InterSystems IRIS — 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. Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Webhook is specific to Easypost and Persistent Classes to InterSystems IRIS — 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. Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Shipment is specific to Easypost and Globals to InterSystems IRIS — 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. Namespaces Namespaces partition databases and determine the connection context for integrations. Address is specific to Easypost and Namespaces to InterSystems IRIS — 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. Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Parcel is specific to Easypost and Stored Procedures to InterSystems IRIS — each maps to any object or custom field on the other side.

How changes propagate between Easypost and InterSystems IRIS

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 InterSystems IRIS 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 InterSystems IRIS as a row-level write, with types converted between the two schemas.

InterSystems IRIS Easypost Interval-based propagation

DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).

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.
  • InterSystems IRIS: Constrained by database resources rather than published API rate limits.
