This document is for a direct API integration with CheckoutChamp. If you are using CheckoutChamp hosted pages then follow these instructions.

Disclaimers:

No card details are stored for merchants using Klarna’s Payment Gateway

Klarna will work for one-time purchases and rebills.

Klarna works with landers that connect to CheckoutChamp via Direct API. Klarna is not available with form-code or via Order Entry.

Make sure Klarna is enabled on your Adyen Account

 

STEP 1

Go to Gateways | Gateway Integrations and select AdyenV2. Click on +Activate. Follow instructions here for setup.

Click the green Create Gateway button to save your changes and create the gateway. Note the ID of the gateway on the gateway list page, for use in Step 2.

STEP 2

The checkout page must be secure HTTPS. A non-secured call to Klarna will be rejected. Pass the following parameters on the Import Order or Import Upsale API call

  • paySource = PREPAID

  • prepaidType = KLARNA

  • forceMerchantId = the AdyenV2 id from Step 1

 

Your checkout and upsale pages must support standard merchant redirect handling
