Online payment methods and wallets

Klarna integration

We have already integrated Klarna in production and connect it to your system: reliable, traceable and monitored in operation.

What is Klarna?

Klarna is a payment provider from Sweden. Customers pay immediately from their bank account, later by invoice or in instalments, depending on market and merchant. Klarna also took over the former Sofort bank transfer.

What we have built

Introduced Klarna in January 2025 as a replacement for the Austrian EPS bank transfer.
Deposits via Klarna straight into the customer account, payment method enabled per market.
Reconciliation of payments with Klarna's settlement reports.

What matters in the integration

Which Klarna payment methods are available depends on country and industry. Clarify this with Klarna early.
A payment can be pending first and confirmed later. The system has to know both cases.
Plan the switch from an existing payment method: communication, parallel operation and switch-off date.

What we build around it

Exactly-once booking: callbacks, webhooks and timeouts handled so that no payment is booked twice or lost.
Payment reconciliation with the provider's settlement reports, automated instead of manual.
Payment method switchable per market, with limits according to the market's rules.
Monitoring and alerting, so that provider outages are noticed immediately.
Test cases and mock interfaces, so that releases can be tested without the real provider.

Frequently asked questions

Can Limeship integrate Klarna into our existing system?

Yes. We have already integrated Klarna in production, in a platform with online portal, apps and branches in several markets. We connect it to your existing backend, whether .NET, Java or another stack, and take over testing, monitoring and operation if you wish.

Can Klarna replace the EPS bank transfer?

In our project it did: in January 2025 we introduced Klarna as a replacement for the EPS bank transfer. Whether this fits your business depends on market, industry and your contract with Klarna.

What do we need to get started?

A contract with Klarna or with the payment service provider that offers Klarna, access to the test environment and the requirements of your business side. We clarify everything else in a first conversation.
