We’re using `Klarna.Rest.Core.Model.CheckoutOptions.AdditionalCheckboxes` to display a checkbox in Klarna Checkout for the user to subscribe to our newsletter. However the value of the checkbox, checked or not checked, is always false/not checked when we read the value after the order has been placed.

We add the checkbox in `KlarnaPaymentConfigV3.UpdateDataSentToKlarna()` and read the value in `KlarnaPaymentConfigV3.ValidateCheckoutOrder()`.

What are we doing wrong?

Also, why is the type of `CheckoutOptions.AdditionalCheckbox` `AdditionalCheckbox` and the type of `CheckoutOptions.AdditionalCheckboxes` `AdditionalCheckboxV2`?

Litium version: 7.4.2

Are you checking `Klarna.Rest.Core.Model.CheckoutOptions.AdditionalCheckboxes` on Validation? I think that will just mirror what you send to Klarna.

Try checking `Klarna.Rest.Core.Model.MerchantRequested.AdditionalCheckboxes` instead.

That’s a question for Klarna 🙂

Right, it’s `LitiumKcoOrder.CheckoutOrder.MerchantRequested.AdditionalCheckboxes` we need to use, thank you!
