What are the Klarna API credentials and how do I use them?
Credentials consist of API username and password. Both are used for authentication when sending API calls to Klarna and to ensure that your integration is secure.To integrate Klarna with your e-store, you’ll need a special set of Klarna API credentials.
To create new credentials as well as manage existing ones:
Log into the Merchant Portal
Select Settings then
.
Good to know: To access the API credentials page, you need to be an Administrator User in the Merchant Portal.
Some platforms have a click-through integration guide. Your API credentials will be generated and connected as part of this process. Creating a set of API credentials outside of this process is not necessary.
You can have multiple sets of Klarna API credentials active. If you have different platforms or partners connected to the same store, you can integrate all of them simultaneously by using multiple sets of Klarna API credentials.
