Greetings all,

I'm having some difficulties processing a payment using the CPayment.ProcessPayment method for the IBOs on IMIS 15.  Within the desktop IMIS interface, we're not having any trouble processing credticard payments via PayPal (the out-of-the-box payment gateway), but whenever I try to invoke the ProcessPayment method using the IBO's, PayPal comes back with a "User Authentication Failed" message.

I've added the below lines to the web.config according to the setup instructions:

     <paymentGatewayService defaultProvider="PayFlowProPaymentGatewayProvider">
      <providers>
        <add name="PayFlowProPaymentGatewayProvider" type="Asi.PaymentGateway.PayflowProPaymentGatewayProvider, PayflowProPaymentGatewayProvider" authorizationAccounts="VERISIGN,PaymentTech"/>
        <add name="NoProcessingPaymentGatewayProvider" type="Asi.PaymentGateway.NoProcessingPaymentGatewayProvider, NoProcessingPaymentGatewayProvider" authorizationAccounts="NOPROCESS"/>
      </providers>
    </paymentGatewayService>

And below is the payment object setup code, address object setup code, etc., so you can kind of see what I'm doing.

// create the payment
CPayment payment = new CPayment(imis_user) {
    PaymentType = EnumPaymentType.CreditCard,
    Amount = 1.00M, //this.TotalDue,
    CashAccountCode = card_type,
    CreditCardNumber = card_number,
    CreditCardSecurityCode = card_security,
    CreditDebitCardHoldersName = name_on_card,
    CreditCardExpiration = card_expiration.ToString("MMyy"),
    CreditDebitCardAuthorizationCode = "1"
};

// create the address
CAddressBasic caddress = new CAddressBasic(imis_user) {
    Address1 = address.Street1,
    Address2 = address.Street2,
    City = address.City,
    StateProvince = address.StateProvince,
    PostalCode = address.PostalCode,
    Country = address.Country
};


PayflowProPaymentGatewayResponse pg_response =
    payment.ProcessPayment(TransactionType.Sale, caddress) as PayflowProPaymentGatewayResponse;

Any help or insight as to what I might be doing wrong would be greatly appreciated.  Thanks much!
