I have logged in to the Merchant Portal to integrate. How does it work?

Step 1
Complete all your company details, including your store name, the webpage’s URL, the email address of the authorized signatory, organisation number, VAT-number, the country in which you are registered, sales segment.

Step 2
You will receive your Klarna API Credentials, your Merchant ID and a shared secret which enables the possibility to take orders. In this step you will also be granted access to test credentials that you can use to make test purchases in your checkout before going live.

Step 3
Activate your payouts. Before doing so you need to integrate your live credentials in your platform.
