Sign up & Sign in
When working with Klarna, you'll need to sign up for both a live and a developer account.
To sign up for a live account, head on over to the Klarna site and select to sign up as a seller from their Klarna for business menu.
For a developer account, you'll need to go to the Klarna developer portal and select your region to request a developer account.
NB Both sign up processes can take a while so be sure to sign up well in advance of going live.
Once you have signed up you'll need to sign in to both of the following portals and follow the remainder of the steps in each portal to get your dev and live credentials.
Once you are signed in to the Klarna portal, click the Settings option at the bottom of the menu on the left hand side and then select the Klarna API Credentials heading.
Next click the Generate new Klarna API Credentials and then click Create Credentials in the dialog that follows. You'll then be presented with a username and password that you'll need to note down for later.
Viewing / Managing Orders
When you start taking orders, you'll be able to view and manage your Klarna orders from the Orders section linked to from the menu on the left hand side.
