Connect Klarna and Shopify

Connecting Klarna and Shopify for a company that uses both could enable automated payment processing within the Shopify storefront, support for Klarna payment methods at checkout, and streamlined order reconciliation. Such a connection could reduce manual entry and simplify financial tracking by linking customer transactions between the e-commerce and payment platforms.

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

Why connect Klarna and Shopify?

A company operating both Klarna and Shopify could benefit from connecting these systems to enable the exchange of critical business data. Such a connection could help ensure that information such as order details, payment status, and customer data remains consistent across both platforms. Without this kind of data exchange, staff might have to enter the same information into each system manually, increasing the risk of errors and consuming valuable time. This manual process could also lead to records in Klarna and Shopify diverging, which can result in decisions being made based on outdated or incomplete information. Common types of data that could be exchanged between payment and e-commerce systems include transaction records, order statuses, refunds, and customer contact details. The specific data that can be exchanged depends on what each system exposes through its API and must be determined on a case-by-case basis.

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 Klarna and Shopify 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.
