Accept Hosted E00013 C#

[PaceDev]

Not sure where to look for this problem, Trying to get the C# sample code working but the responce is alwasy E00013  Unexpected character encountered while parsing value: h. Path '', line 0, position 0."

    public static string GetCheckoutPage(String ApiLoginID, String ApiTransactionKey, decimal amount)
    {
        Console.WriteLine("GetAnAcceptPaymentPage Sample");
        ApiOperationBase<ANetApiRequest, ANetApiResponse>.RunEnvironment = AuthorizeNet.Environment.SANDBOX;
        ApiOperationBase<ANetApiRequest, ANetApiResponse>.MerchantAuthentication = new merchantAuthenticationType()
        {
            name = ApiLoginID,
            ItemElementName = ItemChoiceType.transactionKey,
            Item = ApiTransactionKey,
        };

        settingType[] settings = new settingType[3];

        settings[0] = new settingType();
        settings[0].settingName = settingNameEnum.hostedPaymentButtonOptions.ToString();
        settings[0].settingValue = "{\"text\": \"Pay\"}";

        settings[1] = new settingType();
        settings[1].settingName = settingNameEnum.hostedPaymentOrderOptions.ToString();
        settings[1].settingValue = "{\"show\": false}";

        settings[2] = new settingType();
        settings[2].settingName = settingNameEnum.hostedPaymentIFrameCommunicatorUrl.ToString();
        settings[2].settingValue = "https://localhost:44397/WebPort/IframeCommunicator.aspx";

        var transactionRequest = new transactionRequestType
        {
            transactionType = transactionTypeEnum.authCaptureTransaction.ToString(),    // authorize capture only
            amount = 200.00m //amount

        };

        var request = new getHostedPaymentPageRequest();
        request.transactionRequest = transactionRequest;
        request.hostedPaymentSettings = settings;

        // instantiate the contoller that will call the service
        var controller = new getHostedPaymentPageController(request);
        controller.Execute();

        // get the response from the service (errors contained if any)
        var response = controller.GetApiResponse();
        string token = string.Empty;
        if (response != null && response.messages.resultCode == messageTypeEnum.Ok)
        {
            token = response.token;
        }
        else if (response == null)
        {
            token = "Unable to connect to Authorize.net Please refresh the page and try again.";
            return token;
        }

        return token;

Correction:

        settings[2] = new settingType();
        settings[2].settingName = settingNameEnum.hostedPaymentIFrameCommunicatorUrl.ToString();
        settings[2].settingValue = "https://localhost:44397/WebPort/IframeCommunicator.aspx";

was causing the issue, I forgot to escape the ". I now get back a token.

But the pop up says Missing or invalid token. Is there a way to validate a Token?

 settings[2] = new settingType();
 settings[2].settingName = settingNameEnum.hostedPaymentIFrameCommunicatorUrl.ToString();
 settings[2].settingValue = "{\"url\": \"https://YOUR_FANCY_WEBSITE.com/icommunicator.aspx\"}";

Test token: https://nexwebsites.com/authorizenet/token-tester.html

By the way,  the input name for the token needs to be "token". 

 name="token"
