Great! I will try that! I have a account request for the old V2 at Klarna but the customer is running V3 so this code will be good for testing.

First test did end up here : // If no Klarna order was found to update or the session expired - then create new Klarna order

                if (klarnaOrder == null)
                {
                    klarnaOrder = client.NewCheckoutOrder(klarnaOrderId);
                    klarnaOrder.Create(klarnaOrderData);
                    klarnaOrderData = klarnaOrder.Fetch();

                    order.TransactionInformation.TransactionId = klarnaOrderData.OrderId;
                    order.TransactionInformation.PaymentState = PaymentState.Authorized;
                    order.Save();
                }

ex = BadRequest (400)

Awesome. Is this using the v2 or v3 provider? If the later, did you need to change any of the code?

It's the V3 provider but the code from the clone didnt work so I copy your code directly and put it in a new Klarna.cs file.

Sorry I was in a great mode yesterday that I forget that I didnt get this row to work:

var klarnaOrderId = order.TransactionInformation.TransactionId;
and this:

LoggingService.Instance.Error

Hmm, I'm not sure why those wouldn't work. I've done some testing and not hit any issues with those.

I've updated my PR on GitHub if you want to try it. I've run several orders through it and it should all work. I still need to write the docs for it though.

I will say, I've ultimately made the provider work the same as the previous provider which I think has some specific setup requirements, in that, when using this payment provider I don't think you are meant to collection billing / shipping info yourself, it appears to be built such that the checkout captures these and then the payment provider writes them back to the order so anything you do capture will get overridden.

Also, this payment provider doesn't itself support capturing / refunding so this will all need to be done via the Klarna UI. As I say though, this is as per the current payment provider.

I do think a better provider could be produced that supports all of these things, but unfortunately it's not currently high on my priority list.

Never the less, I hope this helps.

Hey Adam,

You can use it for now yea, it won't hurt.

I don't think you need to collect your shipping info as I think you can tell Klarna to collect it and then like I mentioned above, it is setup to copy all the values back, so when using Klarna you should be able to pretty much go from Cart to Klarna Checkout.

Oh, the one thing you might want to do is create a TC admin order view that uses the relevant named order properties as fetched from Klarna (I don't think the default one uses the same property aliases)

Hi Matt,

Did you get all the products from cart in too Klarna in your testing?

Only got 1 line in and the total sum correct.

Hi Adam,

The Klarna provider only sends through a single item which represents the order as a whole. This is how the original provider was developed so I just replicated the behaviour.

Ok, then it´s not an bug :) Thanks!
