Our In-app API is available for iOS, Android and React Native. The easy setup is straightforward and it won’t be long until you can start accepting payments. We’ve got you covered with different integration options to help you accept payments in your iOS or Android app.

Native Integrations

We offer a native view with Klarna content in your app. We currently support Klarna Payments and Klarna Checkout, allowing you to add payment views to your checkout and authorizing Klarna Payments sessions natively.

Hybrid Integration

If your app renders in a web view that presents content from Klarna, you can use our hybrid integration to enhance the user experience.


Here you will find the integration guides, API documentation for those wanting to integrate directly with our systems, and more to help you get started.
