Hi Finn,

I'm not entirely sure of your setup, or which URLs you are actually calling, but from within process callback method, returning a result with transaction info defined on it will finalize the order if it is not finalized already. You shouldn't need to call finalize there yourself.

    public override CallbackResult ProcessCallback(OrderReadOnly order, HttpRequestBase request, InvoicingSettings settings)
    {
        return new CallbackResult
        {
            TransactionInfo = new TransactionInfo
            {
                AmountAuthorized = order.TotalPrice.Value.WithTax,
                TransactionFee = 0m,
                TransactionId = Guid.NewGuid().ToString("N"),
                PaymentStatus = PaymentStatus.Authorized
            }
        };
    }

I could probably do with knowing your setup in a bit more detail, including what URLs are getting called and from where to give you a more detailed answer.

Hi Matt,

I'll try to keep it brief and simple.

We're using a payment provider that needs an xml string sent via a form to process payment. Part of that xml string hold a successURL and a callback url.

The successURL is just to redirect the user back to the site instead of keeping them on the payment provider site, nothing fancy. I've tried to redirect to "/checkout/order-confirmation" but there seems to be an interal redirect that's probably caused by the payment not being processed via vendr or an approved payment provider.

The callback Url (this goes to an umbraco surface controller) receives back an xml string in the Request Body that holds some of the payment information like a transactionId and the total amount paid but most importantly it holds the information about whether it was successful or not.

So on that callback method I'm trying to get ahold of the current order and finalize it to make sure it shows up in the backend and can be processed by the team to send out the products to the customer.

I hope this makes more sense. Please let me know if there is anything else I can provide to clarify.

Thanks for trying to help, I really appreciate it.

So we have several steps that are all done by the book through Vendr. 1) checkout/customer-info => collects name, address, etc. 2) checkout/shipping-method => let's customer choose how to ship products 3) checkout/payment-method => let's customer choose the payment method of which there is only one anyway 4)checkout/review-order => summary of all data to confirm all is correct

on the 4) review page we have the following code

<form id="frmtest1" name="frmtest1" method="post" action="https://paymentgatewayurl" enctype="application/x-www-form-urlencoded">

<input type="hidden" name="requesttoken" value="foo" />
<div class="border border-gray-300 rounded">
    <label class="flex items-center py-4 px-4 cursor-pointer hover:bg-gray-100">
        <input id="acceptTerms" type="checkbox" value="1" class="mr-3" required="required" />
        <span class="font-medium">I agree and accept the sites terms of service</span>
    </label>
</div>

<textarea cols="80" rows="40" name="xml" id="freetextxml" hidden>
        @xDoc.ToString()
    </textarea>
@Html.VendrCheckoutPartial("VendrCheckoutPrevNext")

When someone clicks on the "go to payment" button that is on the VendrCheckoutPrevNext partial, they're sent to the payment provider where they can enter card details, etc.

the xDoc.ToString() is an xml string that holds information like the amount to pay, some public and secret keys, etc. it also holds

<transactionreference><![CDATA[P637339439052773968:637339439052773968]]></transactionreference>
    <redirecturl><![CDATA[https://foobar.com/checkout/order-confirmation]]></redirecturl>
    <callbackurl><![CDATA[https://foobar.com/umbraco/surface/vendrcheckout/wpmcallback]]></callbackurl>
    <cancelurl><![CDATA[https://foobar.com/errors/payment-unsuccessful]]></cancelurl>

So after a customer has paid on the payment providers website, the payment provider will send an xml string in the request body to the callback url to confirm payment has been made. Only this confirms the success of a payment so we can only then finalize the payment in vendr.

And this is where it all falls down because I can't get it to do just that. I have tried using the vendrapi to GetCurrentOrder() but that gives me a unmutable OrderReadOnly object, so I'm getting it via the sessionManager like this

using (var uow = _unitOfWorkProvider.Create())
        {
            var order = _sessionManager.GetOrCreateCurrentOrder(Guid.Parse(App.Current.Settings.StoreId))
                .AsWritable(uow)}

This gives me an Order object that I can call things like Finalize() on. However if I do that, all that happens is that the parameter called isFinalizing is set to true but it doesn't actually finish that process and so it never shows up in the list of orders in the backoffice of Umbraco.

Hi Matt, thank you very much for this. I had looked at the payment provider documentation before but mostly confused myself with it when trying to fit our client's process into this.

Your explanation is helping a lot and I'll get right onto implementing it that way.

Thanks again for your help.

Hi Matt,

I'm still having a bit of an issue with this, unfortunately.

I've implemented the BeginPaymentForm on the review step. That's actually what it was before I started screwing around with it.

I've created a Payment Method of type Invoice and gave it a name and alias which I'm using in my PaymentProvider class as per your example.

When I run through the checkout steps, I get to the review page, no problem. But then I'm taken immediately to the confirmation page, completely bypassing any and all payment structure. The GenerateForm method I've implemented pretty much in the same way you have it in your source code. But when I put breakpoints in that never gets called and I'm just moved on to the next step which is confirmation.

I'm also not sure where to find that callback url. I can see that GenerateForm takes in a parameter of that name but there is no method for it like there is for eg continue url (GetContinueUrl()).

If you have an idea what I might be forgetting to do, I'd really appreciate the input.

Thanks, Finn

Hi Matt,

I've gone to "Payment Method" and created a new Invoice Payment Method because we're not using paypal or any of the already pre-configured payment methods that vendr so handily comes with. As you say it makes total sense that that would bypass the payment process as invoices usually don't need card details from the customer.

So I guess this is where I went wrong and probably have to use a different payment method type?

Thanks for all your help, Finn

Hi Matt,

I just wanted to say thank you for all your help. I can't believe how easy it was to do all that in the end.

It's all set up now and working.

Thanks again for being patient. I'll owe you a pizza.

Thanks, Finn
