Integration with paygate in asp.net

Question

So I have added the service reference to my project which is

https://secure.paygate.co.za/payhost/process.trans?wsdl

My PaygateRef is the web service reference Name(namespace)

PaygateRef.SinglePaymentRequest1 PaygatePayment = new PaygateRef.SinglePaymentRequest1();
PaygateRef.CardPaymentRequestType Request = new PaygateRef.CardPaymentRequestType();
Request.Account = new PaygateRef.PayGateAccountType();
Request.Account.PayGateId = "000000000";   //my PaygateID
Request.Account.Password = "mypassword";       //my Encryption key

Request.Customer = new PaygateRef.PersonType();
Request.Customer.Title = "Mr";
Request.Customer.FirstName = "Rich";
Request.Customer.LastName = "Buyer";
Request.Customer.Mobile = new string[]{"0830000001"}; //My cell number

Request.CardIssueNumber = "500000000000008";//card number
Request.CardIssueDate = "012020";//january 2020
Request.CVV = "001";// card ccv

Request.Order = new PaygateRef.OrderType();
Request.Order.MerchantOrderId = "115422488465";//a random test orderID
Request.Order.Currency = PaygateRef.CurrencyType.ZAR;
Request.Order.Amount = 100;  //R1

PaygatePayment.SinglePaymentRequest = new PaygateRef.SinglePaymentRequest();
PaygatePayment.SinglePaymentRequest.Item = Request;

PaygateRef.PayHOST myPaygateinterface = new PaygateRef.PayHOSTClient();

myPaygateinterface.SinglePayment(PaygatePayment);

The error I am getting is

Validation error

I tested with multiple cards that work on other sites and this account was used on the website previously written in PHP where it was working.
So everything on Paygate side is set up correctly as per my understanding

Why am i getting this error and how do I solve it?

Edited
I did try

Request.ItemsElementName = new PaygateRef.ItemsChoiceType[]
{
    PaygateRef.ItemsChoiceType.CardExpiryDate,
    PaygateRef.ItemsChoiceType.CardNumber
};

Request.Items = new string[] { "012020", "500000000000008" };

Answer 1

I was able to resolve my issue by changing the order of card details. In your case, you have put cardexpirydate above cardnumber. I reversed the order and also ensured that the cvv comes after card details. This will be your code.

Request.ItemsElementName = new PaygateRef.ItemsChoiceType[]
{
    PaygateRef.ItemsChoiceType.CardNumber,
    PaygateRef.ItemsChoiceType.CardExpiryDate

};

Request.Items = new string[] { "500000000000008", "012020" };

Request.CVV = "001";// card ccv

Hope it helps!!!

Also I did not use cardissuedate or cardissuenumber as these are optional and i didn't need.

In addition, you can also check the Details node of the exception that you get. In the details node, it will clearly define the cause of the error.

Answer 2

CardIssuenumber is actually not the card's number and it's optional. had to scratch my head a bit for payhost structure : here is some of the validation you missing? hope this help

request.ItemsElementName = new payhostReference.ItemsChoiceType[] 
{
    payhostReference.ItemsChoiceType.CardExpiryDate,
    payhostReference.ItemsChoiceType.CardNumber
};

request.Items = new string[] { "122017", "4000000000000002"};

A much simplier approach with very easy code to follow do the following.

1. import Nuget restsharp

   Imports RestSharp Imports System Imports System.Data Imports System.Configuration Imports System.Linq Imports System.Web Imports System.Web.Security Imports System.Web.UI Imports System.Web.UI.HtmlControls Imports System.Web.UI.WebControls Imports System.Web.UI.WebControls.WebParts Imports System.Xml.Linq Imports System.Net Imports System.Collections.Specialized Imports System.Text Imports WebApplication1.ServiceReference1

   End Class
