Hi Claus

We have both the old and the new version of Klarna, actually 3 different versions - see the complete list here: https://doc.dynamicweb.com/documentation-9/ecommerce/payment-shipping/checkout-handlers

Also many of the other gateways support Klarna - i.e. Quickpay, Dibs etc. (The pay later/invoice - and Pay now, aka Sofort in other countries than DK).

PartPaymentsExists tag is part of the invoice implementation - which is the feature of pay later using financing (AKA make poor people even more poor).

Hi Nicolai,

Thank you for the quick answer 

Yes exactly, so the old version of Klarna payments (not Klarna checkout) is the reason I'm asking, because i don't see the pay now for this version of Klarna in DW https://developers.klarna.com/documentation/klarna-payments/.

I imagine it requires a new checkout handler written for the payments api and corresponding templates for e.i widget display if pay now is to be supported ?

Why is it not this one: https://doc.dynamicweb.com/documentation-9/ecommerce/payment-shipping/checkout-handlers/klarna-checkout-v3?

Because our customer has agreement on Klarna Payments and the api's differ :)

Unless DW's checkout handler kan handle Klarna payment acounts with checkout v3.

Going in circles...

https://doc.dynamicweb.com/documentation-9/ecommerce/payment-shipping/checkout-handlers/klarna-checkout-v3 is v3. Hence the name...

Did we sort this one out?

@Nicolai: What about support in Dynamicweb?

"Also many of the other gateways support Klarna - i.e. Quickpay, Dibs etc."

According to DW support its not possible to use the Quickpay-gateway with Klarna.

From https://learn.quickpay.net/tech-talk/appendixes/acquirer-details/#acquirer-details:

• Payment must contain full customer invoice address and/or shipping address.
• Payment must contain basket.
• shipping[amount] must contain shipping costs for the order
• Customer country and currency must match.
• vat_rate must be a part of the refund request.

Its not possible to add/include "full customer invoice address and/or shipping address", right? 

Well, I believe it is possible... Quickpay just released an updated integration using Klarnas new APIs.

You have to change what is posted to Quickpay - you can do that by using your own post template - see dump.

Using the required fields from Quickpay: https://learn.quickpay.net/tech-talk/payments/form/#quickpay-form

BR Nicolai

Well - I'm using my own post template, and have added the missing required fields:

• full customer invoice address
• basket
• shipping
• customer country and currency

One of the required values is the checksum: "All request data must be included in the checksum calculation" (from Quickpay).

So, I'll need to calculate a new checksum with all my form data and not just add the required/missing fields.

Hi Morten,

If you need some example of how to calculate the checksum, you can see it on quickpay portal https://learn.quickpay.net/tech-talk/payments/form/#examples

but please pay attention to notice "Note: The checksum is calculated only from QuickPay specific parameters. If you for some reason submit other parameters, those will not be part of the checksum."

BR, Viktor.
