Shopify orders write into IBM AS/400 records and AS/400 stock and pricing return to the storefront, so a long-standing system serves modern e-commerce without its programs being rewritten.
Businesses selling on Shopify while running operations on an IBM AS/400 often bridge the gap with overnight files or a screen-scraping workaround. Without a dependable link, Shopify orders are typed into green-screen programs by hand, stock in the AS/400 never reaches the storefront in time, and nobody wants to touch RPG code that has run untouched for years. Connecting Shopify and IBM AS/400 through Alumio exchanges orders, stock, and pricing through configuration, so the storefront trades on current data without a rewrite of the existing system.

Alumio connects to the AS/400 directly at database level, so Shopify trades against the existing system rather than waiting on a rewrite of software nobody wants to reopen.
Shopify orders land in the AS/400 automatically, so staff stop entering web sales through green-screen forms and the transcription errors that come with it disappear.
AS/400 stock and pricing reach Shopify on a short cycle, so the storefront reflects the system of record instead of a file that was accurate when it was generated last night.
With Shopify and IBM AS/400 connected through one hub, adding a marketplace or a PIM later reuses the same setup rather than another overnight file to schedule and monitor.
When a customer checks out on Shopify, Alumio writes the order into the AS/400 order records with its lines and customer, so fulfillment and invoicing run as normal without anyone rekeying the sale into a green-screen program.
When stock or pricing changes in the AS/400, Alumio pushes the values to the matching Shopify products, so shoppers see what the system of record holds rather than figures from an overnight extract already hours out of date.
When the AS/400 records a shipment, Alumio updates the Shopify order and its tracking, so the customer is notified automatically and staff no longer copy dispatch details out of a terminal session by hand each time.
Alumio sits between sales channels and fulfillment systems as a governed integration backbone. Orders are routed, transformed, and validated, while status updates return to every channel.
Authenticate your systems using Alumio's pre-built connectors. Choose from 200+ connector packages in the marketplace, plus unlimited custom integrations.
Define how data fields map between systems in a visual interface. Adjust formats, enrich records, and apply business logic, no custom code required.
Configure flows to run in real time on events, on a schedule, or both. Reduce manual data entry and let Alumio handle movement and transformation between systems.
Once your first integration is live, adding your ERP, PIM, WMS, or CRM connects to the same hub. Existing flows keep running. No rebuilding from scratch.
Yes. Businesses modernizing around an AS/400 usually add a PIM or a warehouse system next, and each would otherwise mean another custom extract from the same machine. Alumio connects them through one hub, reusing the AS/400 configuration already built, so new systems read the same records without additional programs being written on the legacy side.
Yes. Alumio writes Shopify orders into AS/400 records and returns stock and pricing to the storefront, without overnight files. You control the frequency of each flow, so orders can be written as they arrive while stock reads run at an interval that suits the machine's workload and avoids competing with batch processing.
No. The alternatives teams usually face are new RPG programs, a nightly file interface, or screen scraping, all needing specialist maintenance. Alumio connects directly at database level instead, with the field mappings held as configuration. Where a fixed-width layout or packed field cannot be mapped as it stands, the Code Transformer converts it in that one step, so nobody reopens programs written decades ago.
Yes. Alumio connects to legacy and on-premise systems directly at database level, so an AS/400 can serve a modern storefront without being replaced or rewritten first. The integration logic lives in Alumio rather than in programs written decades ago, which matters when the original developers have moved on: connecting Shopify becomes a configuration exercise instead of a change to business-critical software.
The failure surfaces the moment the AS/400 refuses a record rather than at the end of a nightly run, so nobody assumes a Shopify order was processed when it was not. Alumio keeps a live log showing which order was rejected and the exact error, for instance a customer number the file layout will not accept. Where configured it retries on its own, and if the record still will not write the order is named in an alert, so no web sale is silently lost.
