Connect Klarna and Sylius

Connecting Klarna and Sylius could enable a company to automate payment processing and order management between the two platforms. This could reduce manual data entry, improve transaction accuracy, and support more efficient reconciliation of sales and payments. Integration could also help ensure that payment statuses are accurately reflected in both systems.

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

Why connect Klarna and Sylius?

A company operating both Klarna and Sylius could benefit from connecting the two systems to enable data to flow automatically between their e-commerce platform and payment services. Without such a connection, staff might need to manually enter order, payment, or customer information in both systems, increasing the risk of errors and consuming valuable time. This manual process can result in records in Klarna and Sylius gradually becoming inconsistent, with mismatches in order statuses, payment confirmations, or customer details. Such discrepancies could lead to operational inefficiencies, customer service issues, and decisions based on outdated or incomplete data. If a connection were established, the types of data that could be exchanged between an e-commerce platform like Sylius and a payment service like Klarna include order details, payment statuses, customer information, and refund transactions. Automated data exchange could help ensure that both systems reflect the same information, supporting more accurate reporting and smoother customer experiences. However, what can actually be exchanged depends on what each system exposes through its API and is determined for each situation individually.

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 Sylius 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.
