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 only work for one-time purchases. Klarna will NOT work for recurring billing/subscriptions. Please contact your account manager if you need to rebill on Klarna.
Klarna does not support one-click upsells. Upsells on Klarna require the consumer to go through the full Klarna checkout again.
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
For more info on the api call, please refer to our API Documentation.
