You have two different ways to present Klarna in your checkout, depending on whether you build your own payment form or rely on Worldline's Hosted Payment Page.
Option 1: Build your own payment form
If you manage your own checkout UI, you can integrate Klarna in one of the following ways:
1. Klarna web SDK
Use our web SDK to build the payment selector and offer Klarna as a payment method in your checkout.
- Build the payment form using Klarna API's.
2. Worldline's GET Payment Products API
Alternatively, you can use Worldline's API to retrieve available payment methods and Klarna presentation assets to build your payment form.
Option 2: Use Worldline's Hosted Payment Page
If you rely on Worldline's Hosted Payment Page and don't build your own payment selector, Klarna will be shown by default.
To customize the Hosted Payment Page, follow the configuration guide for your specific Worldline platform:
- Global Collect: Configuration Guide
