There are a few customization options available for the checkout placement. It can be enabled or disabled within the ShopPay checkout. We recommend this to be enabled as customers may struggle to navigate to Klarna from the ShopPay checkout without guidance. You can add this by clicking Checkout behavior in the app settings and checking the box Include app block in Shop Pay.

We offer customized messaging for this purpose that can be enabled by reaching out to your partner success team or merchant@klarna.com.

Error messaging in the settings are descriptive and will explain in what cases (and with which settings) the messaging will not show to your customers. An example of this is if a customer country is not enabled on your Klarna merchant ID. In such a case the messaging would not be displayed to customers in that country as they would not be able to proceed with Klarna as a payment method.
