I am using https://github.com/TeaCommerce/Payment-providers/blob/master/Source/TeaCommerce.PaymentProviders/Classic/SagePay.cs

in my model

[PaymentProvider("SagePay")]
public class SagePay : APaymentProvider 
{...... 

So my final page in the order process instantiates a new SagePay() object and

 SagePay mysp = new SagePay();
PaymentHtmlForm myform = mysp.GenerateHtmlForm(order, "a success url", "a fail url", "http://...path/getCallbackFromSagepay", "", settings);

The Callback url (from Sagepay to website) goes to:

public ActionResult getCallbackFromSagepay(SagePayResponse response)
    {
        Order order = TC.GetCurrentOrder(1,false);
        Dictionary<string, string> settings = new Dictionary<string, string>();
        settings["AddressResult"] = response.AddressResult;
        settings["PostCodeResult"] = response.PostCodeResult;
        settings["AVSCV2"] = response.AVSCV2;
        settings["CV2Result"] = response.CV2Result;
        settings["AddressStatus"] = response.AddressStatus;
        settings["PayerStatus"] = response.PayerStatus;

and all the other SagePay response properties THEN

string setSignature = response.GenerateSignature(order.Properties["securityKey"], "vendor name");

string sig = response.VPSSignature;
settings["vpsMySignature"] = setSignature;
SagePay mysp = new SagePay();
TeaCommerce.Api.Web.PaymentProviders.CallbackInfo mycbi =  mysp.ProcessCallback(TC.GetCurrentOrder(1), myreq, settings);

(myreq is a url I have entered which I know is incorrect but this is where one of my questions relates)

Now it calls the PROCESSCALLBACK in the class SagePay : APaymentProvider

string a = mycbi.TransactionId.ToString();
Log.Add(LogTypes.Debug, 1314, " TRANSACTION ID = " + a);
order.Finalize(mycbi.AmountAuthorized, mycbi.TransactionId, mycbi.PaymentState);

I then try to either redirect (umbracopage) or call another action (fails here)

So all of the above uses both the

PaymentHtmlForm GenerateHtmlForm
public override CallbackInfo ProcessCallback( Order order, HttpRequest request, IDictionary<string, string> settings )

in the SagePay payment provider.

and I have replicated the PaymentProvider class as a model in my project.

For now I do not make any call to

public class RestExtensions

and I have not seen any documentation which indicates how this is used with the TeaCommerce Payment Providers/SagePay.cs

thanks

So when I use CartStep4 it generates the following form action:

http://my_domain_name/base/TC/PaymentCancel/1/SagePay/75fd4a7e-7d69-4d00-bb30-5fe811276270/887681b11375f2526952a9b01efe5075552522f9616de17a600b2724cac7693e.aspx

which returns me to the Fail page

Nearly there. Everything works except Unable to redirect to Vendor's web site. The Vendor failed to provide a RedirectionURL.

In the back office I have tried both fully qualified url and relative url for both ContinueURL and CancelURL (also have SuccessURL and FailureURL)

In SagePay.cs I have tried hard coding lines 104-106 with full urls (I thought the NotificationURL was the RedirectURL)

Does the page which NotificationURL points to need to call a function in the SagePay Payment Provider to send a request back to SagePay?

Here is log

Excellent got it working. Many thanks
