TPU: Release notes 23-09-2025

Added support for Klarna Extra Merchant Data. We have added the field klarnaMerchantData to the optimize input on the Order:Create API. We pass any data in that field through to Klarna as extra merchant data. For more information about Klarna Extra Merchant Data please visit https://developer.pay.nl/docs/klarna#/
Added support for the sl_SI locale in the creditcard payment screen
Updated the required input for the DirectDebit payment method:
- The firstName and lastName fields are now optional.
- Added new required field accountHolder.
- For backwards compatibility the firstName and lastName are used as the accountHolder when the accountHolder field was left empty.
Fixed an issue where payments for payment methods requiring user input would expire too soon.
PayPal: We will now deny all PayPal payments of the type ECHECK. We have seen many cases where this leads to fraud due to the check never being paid. To protect our merchants we will not allow these types of payments anymore.
