Klarna Docs - In-App SDK

In-App SDK

With Klarna’s In-App SDK, you can provide your customers the smoothest checkout experience in your app, regardless of how it’s built.


The In-App SDK allows merchants to natively integrate Klarna’s products into their apps. This means that you can add services like Klarna Payments to your app and let your customers pay with our payment methods.
