Connect Shopify and IBM AS/400

Connecting Shopify and IBM AS/400 could enable a company to automate the transfer of sales, inventory, and customer data between its e-commerce platform and legacy business systems. Such an integration could reduce manual data entry, improve data consistency, and support more efficient order fulfillment and financial reporting processes across both environments.

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

Why connect Shopify and IBM AS/400?

A company that operates both Shopify and IBM AS/400 could benefit from connecting the two systems to enable data exchange between their e-commerce platform and their legacy enterprise resource planning or business management infrastructure. If the systems remain isolated, staff may need to manually re-enter orders, inventory levels, or customer data from Shopify into the AS/400 environment, which could introduce errors, consume valuable time, and lead to inconsistencies between records. Over time, this separation could result in discrepancies such as mismatched stock levels, outdated pricing, or customer records that do not reflect recent transactions, making it harder for teams to make informed decisions or provide accurate service. If a connection were established, it could allow for the transfer of data such as sales orders, inventory updates, product information, and customer details between Shopify and IBM AS/400. This could reduce administrative workload, help maintain data accuracy across both platforms, and support more timely business insights. The specific data that can be exchanged would depend on the capabilities each system exposes through its API or other integration methods, and would need to be determined for each individual case.

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 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.
