Business Central + Klarna

Open the Business Central connector in Junipeer

Start the Business Central connection from the relevant connector or onboarding step in Junipeer.

Click Connect

Use the connect action in Junipeer to start the Microsoft sign-in flow.

Sign in with the right Microsoft account

Choose the Microsoft 365 or Microsoft Entra account that has access to the Business Central environment Junipeer should connect to.

Review and approve the OAuth consent

Microsoft shows the requested permissions before you approve the connection. Continue only if the tenant and account are correct.

Confirm environment or company if needed

If Junipeer asks you to choose an environment or company, select the one that should be connected.

Return to Junipeer and verify the connection

After the approval flow completes, go back to Junipeer and make sure the Business Central connector is connected.

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.
