Connect Klarna and CommerceTools

Connecting Klarna and CommerceTools for a company could enable the exchange of payment and order data between the two platforms. This connection could support automated payment processing, order status updates, and reconciliation, helping to reduce manual entry and improve operational efficiency. Integration would require technical planning, security considerations, and ongoing maintenance.

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

Why connect Klarna and CommerceTools?

A company operating both Klarna and CommerceTools could benefit from connecting these systems to enable data exchange between their payment processing and e-commerce operations. Without such a connection, staff may need to manually enter or reconcile order, payment, and customer information in both systems, which increases the risk of data entry errors, duplicated records, and inconsistencies. Over time, this can result in records that do not match between systems, leading to confusion, inefficient workflows, and decisions based on outdated or incomplete information. When both systems are used independently, there is also a higher administrative burden, as teams must check and update records in multiple places to maintain accuracy. If Klarna and CommerceTools were connected, data such as order details, payment statuses, customer information, and refund transactions could be exchanged between them. This could help ensure that e-commerce transactions processed through CommerceTools are automatically reflected in Klarna’s payment records, and vice versa, reducing manual intervention and improving data accuracy. 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 Klarna and CommerceTools 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.
