Connect Klarna and BigCommerce

Connecting Klarna and BigCommerce for a company that uses both could allow payment transactions processed through Klarna to be reflected within the BigCommerce platform. This could support automated updates to order statuses and financial records, reducing manual entry and supporting more accurate reconciliation between sales and payments.

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

Why connect Klarna and BigCommerce?

A company operating both Klarna and BigCommerce could benefit from connecting these systems to enable more efficient and accurate data flow between their e-commerce platform and payment solution. If these systems remain isolated, staff may need to enter the same information in both places, which can be time-consuming and prone to errors. For example, order details or payment statuses entered manually in one system but not updated in the other may lead to inconsistencies. This can result in mismatched records, difficulties in reconciling accounts, and the risk of making business decisions based on outdated or incomplete data. If a connection were established, it could allow for the exchange of data such as order information, payment confirmations, refund statuses, and customer details. This would help ensure that both systems reflect the same up-to-date information, reducing the administrative burden and minimizing the risk of discrepancies. However, the specific data that can be exchanged depends on what each system exposes through its API and must 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 Klarna and BigCommerce 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.
