Connect Shopify Plus and IBM AS/400

Connecting Shopify Plus and IBM AS/400 for a company could enable the transfer of order, inventory, and customer data between the e-commerce platform and the legacy enterprise system. This could support automated updates, reduce manual data entry, and improve the accuracy of business operations by keeping both systems aligned with current business activities.

You can build this integration on the System2System platform. We design the connection between Shopify Plus and IBM AS/400 around the way you work — not as an off-the-shelf connector, but to fit your systems.

Why connect Shopify Plus and IBM AS/400?

A company operating both Shopify Plus and IBM AS/400 could benefit from connecting the two systems to streamline business processes and reduce operational friction. When these systems are not connected, staff may have to manually enter the same data in both platforms, which can lead to errors, inconsistencies, and wasted time. Over time, records in each system could diverge, resulting in mismatched inventory levels, outdated customer information, or financial discrepancies. Decisions might then be made based on incomplete or stale data, impacting customer satisfaction and business performance. If a connection were established, it could enable the exchange of data such as product details, inventory levels, customer records, and order information. For example, sales made on Shopify Plus could be automatically reflected in the IBM AS/400 system, and inventory updates in AS/400 could be pushed back to Shopify Plus. This would help ensure that both systems remain aligned and that business decisions are made using current data. However, what can actually be exchanged depends on what each system exposes through its API, and is determined per situation.

How System2System builds an integration

Connectors

We connect to each system through the interface it offers — an API, a database, a file exchange or a webhook — and handle authentication, rate limits and retries.

Mapping

Fields rarely line up one to one. We map and transform the data so both systems receive it in the shape they expect.

Workflow

We define what triggers an exchange, in which direction data flows and which system takes precedence when the two disagree.

Monitoring

Every exchange is logged. Failures are flagged and can be replayed, so nothing disappears without anyone noticing.

What can actually be exchanged?

That depends on what Shopify Plus and IBM AS/400 make available through their APIs, on the licences and modules in use, and on the version each system runs. Which records are synchronised, in which direction and how often, is something we determine together before any work starts.

We are happy to look at your specific situation and tell you what is feasible — including when the answer is that it is not.
