Fortnox + Klarna

Create or choose the integration user

Open Fortnox user administration and create or select the user that will be used for the Junipeer connection.

Add the required licences

Ensure the user has licences for Orders, Invoices, Accounting, and Integration.

Enable the required permissions

Assign the licences to the user and enable all permissions the integration needs.

Connect Fortnox in Junipeer

In Junipeer, click the Fortnox connector, sign in with the prepared user, and approve access.

Open Merchant Portal or contact Klarna support

Retrieve the API credentials from the Klarna Merchant Portal. If they are not available there, contact your regional Klarna merchant support team.

Locate the API key

Find the API key that matches the environment you want to use. Klarna API keys follow the format `klarna_<live|test>_api_...`.

Save the credential details securely

If Merchant Portal also shows a UUID username together with the API key, save that as well in case a legacy username/password client needs it.

Confirm the environment

Use test credentials for playground or testing, and switch to live credentials when you are ready for production.

Paste the credentials into Junipeer

Enter the Klarna API key in Junipeer. Only add the UUID username if Junipeer or the specific integration setup explicitly asks for it.
