Klarna + Visma.net

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.

Open the Visma.net connector in Junipeer

Start the Visma.net connection from the relevant connector or onboarding step in Junipeer.

Click Connect

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

Sign in with the correct Visma account

Choose the Visma account that has access to the Visma.net environment and company that should be connected.

Approve the requested access

Review the OAuth consent screen in Visma Connect and approve the connection if the account and environment are correct.

Return to Junipeer and verify the connection

After the approval flow completes, go back to Junipeer and make sure the Visma.net connector shows as connected.
