Use this article to understand what changed when access to the Klarna Merchant Portal and Klarna's API ended for merchants operating through Kustom, and what to do if you need help with orders, refunds or reports from before your move to Kustom.

Since September 15, 2026, merchants operating through Kustom no longer have access to the Klarna Merchant Portal or Klarna's API:

Kustom continues to support you through Kustom support channels.

Refunds and order management for orders that were originally placed through Klarna, before your move to Kustom, are not supported through the Klarna Merchant Portal or Klarna's API.

If you need to refund or manage one of these legacy Klarna orders, handle it in your own systems using your own process. Read more in Handling refunds on legacy Klarna orders.

Customers can open a Klarna dispute up to 180 days from the date of capture. All orders processed by Klarna passed this dispute window on September 25, 2026, so new disputes on legacy Klarna orders are not expected.

Exception for fraud-related disputes: If a customer contacts Klarna Customer Service directly by phone or email to report an unauthorized purchase, Klarna can open a dispute on their behalf up to 395 days from the date of capture. Dispute management for legacy Klarna orders is not available in the Klarna Merchant Portal or Klarna's API, so contact Kustom support if this happens.

For more detail on Klarna's dispute time limitations, see Klarna's dispute management documentation.

Historical settlement reports and transaction data from Klarna are no longer available in the Klarna Merchant Portal or through Klarna's API. If you need historical Klarna reports, contact Kustom support and we can help retrieve the data for you.

For orders placed through Kustom, everything works as normal. Checkout, order management, payouts and settlements are all handled through the Kustom Portal and the Kustom API.

Legacy Klarna orders, including refunds, disputes and settlement data, are not managed in the Kustom Portal. You are responsible for handling them in your own systems and processes.
