From September 15, 2026:

Kustom will continue to support merchants via Kustom support channels.

After September 15, refunds and order management for orders that were originally placed through Klarna are not supported via the Klarna Merchant Portal or Klarna's API.

If you need to issue a refund or manage an order from before the migration, this must be handled in your own systems using your own process. Read more in Handling refunds on legacy Klarna orders.

No new disputes can be opened after 180 days from the date of capture. This means that by September 25, 2026, all orders processed by Klarna will be past the dispute window — so new disputes are not expected after that date.

Any disputes that are still open should be resolved before September 15, 2026. After that date, dispute management for legacy Klarna orders is not supported via the Klarna Merchant Portal or Klarna's API.

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

If you need historical settlement reports or transaction data, download and save it from the Klarna Merchant Portal or via Klarna's API before September 15, 2026. After that date, this data will no longer be accessible through the portal or API.

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

Legacy Klarna orders — including refunds, disputes, and settlement data — are not managed by Kustom. You are responsible for handling these before September 15, 2026, using your own systems and processes.
