    klarnapaylater: Failed to create Mollie payment object for order 123456789: [2025-08-21T09:10:03+0000] Error executing API call (422: Unprocessable Entity): The 'billingAddress.givenName' field contains characters that are not allowed..

    In this case the First name was Evelin + Jörg

    So my best guess is the + character is not allowed.

    Also you might need to check if German Umlauts and the ß are allowed…

    Hello @homepagehelden

    Thanks for raising this. I have forwarded this to the developers, and they are taking a look.

    I will let you know as soon as they have an update.

    Regards,
    Femi.

    Same should be done with the telephone number. If it has no country code or something, also the “422: unprocessable entity” error arises for example with Paypal.
