Klarna Checkout SDK for Mobile Apps

Warning

This library has been deprecated as Klarna Checkout is now supported by the Klarna Mobile SDK.

The Checkout SDK allows to integrate Klarna Checkout in native or hybrid iOS and Android applications. It's aimed to make integration simple and provide the smoothest in-app purchase experience.

What does Klarna Checkout SDK Offer?

Klarna Checkout SDK offers two integration approaches: Native integration and Hybrid integration.

In the Native approach, your mobile app presents the Klarna Checkout view using our mobile SDK. The mobile SDK requests the Klarna checkout HTML snippet from Klarna through your end point. Your back-end acts as a communication tunnel.

In the Hybrid approach, your mobile app displays the Klarna checkout as a WebView. Your back-end acts as a web server, rendering the Klarna Checkout on a web page that you host, presented in the WebView in your mobile app.

Overview

Native Integration

The components in the Native approach are:

• An integration of Klarna Checkout from your servers to Klarna's servers.
• An end-point on your servers, where Klarna Checkout is fetched from the mobile SDK.
• Klarna Checkout SDK for mobile apps.
• Your mobile app.

Integrating Klarna Checkout consists of six steps:

1. Installation of Klarna Checkout.
2. Prepare your app by changing the configuration or app manifest.
3. Prepare backend endpoint to fetch a Checkout snippet.
4. Initialie the SDK with the Checkout snippet.
5. Present the Klarna Checkout view.
6. Configure event listeners.

Hybrid Integration

The components in the Hybrid approach are:

• An integration of Klarna Checkout from your servers to Klarna's servers.
• A web page on your servers, where Klarna Checkout is fetched from the mobile SDK.
• Klarna Checkout SDK for mobile apps.
• Your mobile app.

Integrating Klarna Checkout consists of six steps:

1. Installation of Klarna Checkout.
2. Prepare your app by changing the configuration or app manifest.
