Old function currently in use to encrypt the credit card using BOI.  This works (and is still is in production for our MAS 200 4.5).  The main thing to know is the function name: “nCreditCardEncrypt”  If I did not know that I could never have gotten this to operate.  I need to know the new function names and types for adding a card to the Vault! 

       static int pvxEncryptCard(object oBus, string sCardIn, out string sEncryptOut, out string LastErrorMsg)
        {

            int retVal = 0;
            string sEncryptCard = "";
            System.Reflection.ParameterModifier pmods = new System.Reflection.ParameterModifier(2);
            pmods[0] = true;
            pmods[1] = true;
            System.Reflection.ParameterModifier[] pMods = new System.Reflection.ParameterModifier[] { pmods };
            object[] Params = new object[] { sCardIn, sEncryptCard }; 

            retVal = (int)oBus.GetType().InvokeMember("nCreditCardEncrypt", System.Reflection.BindingFlags.InvokeMethod, null, oBus, Params, pMods, null, null); 

            sEncryOut = Params[1].ToString();
            LastErrorMsg = pvxLastError(oBus, retVal);
            return retVal; 
        }

I decided just to try everything I can to "discover" the function names. My old function of "nCreditCardEncrypt" works fine for MAS 200 4.5 but is not included in the Sage 100 5.4 system. So, I get a COM exception stating unknown name (of the function)

I can do other functions that are in both 4.5 and 5.4 such as "nSetValue" and it will not fail. So I tried the following (some I found online)  NOTHING I TRIED FOR VAULT/EXCHANGE WORKS.  Please help!

ProcessVault = COM exception stating unknown name
nProcessVault = COM exception stating unknown name
AddCreditCardToVault = COM exception stating unknown name
nAddCreditCardToVault = COM exception stating unknown name
VaultBankcardAuthOnly = COM exception stating unknown name
nVaultBankcardAuthOnly = COM exception stating unknown name
nSetValue = works in both 4.5 and 5.4
nSetUser = works in both 4.5 and 5.4
nSetCompany = works in both 4.5 and 5.4
nSetDate = works in both 4.5 and 5.4
nSetModule = works in both 4.5 and 5.4
nLookupTask = works in both 4.5 and 5.4
nSetProgram = works in both 4.5 and 5.4
NewObject = works in both 4.5 and 5.4

Here is the error but it just means I don't have the "Secret" function names...

System.Runtime.InteropServices.COMException was caught
Message=Unknown name. (Exception from HRESULT: 0x80020006 (DISP_E_UNKNOWNNAME))

OK so the *.pvc files are used by the Sage BOI to perform functions... I searched for any pvc with "creditCard" but I dont have any documentation.  Would I use AR_CreditCard?  That is what I am currently attempting to use but I dont know its internal functions.  What about CI_CreditCardGUID_val?  I should think that something like AR_CreditCard would USE CI_CreditCardGUID_val in order to talk to the Exchange-Vault utilizing the Virtual Terminal ID (Mecrhant ID) and Merchant Key I have stored in the system (The system can use the SAGE UI to post credit card transactions just fine)

AR_CreditCardCommonEntry.pvc
AR_CreditCard.pvc
AR_CreditCardCommon.pvc
AR_CreditCardSPS.pvc
CI_CreditCardConversion.pvc
CI_CreditCardGUID_val.pvc
CI_CreditCardIDUI_val.pvc
CI_CreditCardID_val.pvc

SUCCESS!

Sage\Common Components\wsVault.dll

add as reference in your project.  Then in your code, "using wsVault;"

after adding this library, you can see a list of functions.  Does anyone have any information related to this?  I looked until I found the correct function under "wsVault.net.sagepayments.www" and then inside of "wsVault".  It would be nice to have some documentation

I was able to successfully submit the credit card number and expiration to the Sage Exchange Vault and return the GUID.

I was able to to avoid the extra Vault UI. I had to - as our custom UI is highly optimized and this Vault screen throws off the whole data entry flow.

DataSet vaultReturnDS;
wsVault.net.sagepayments.www.wsVault sageVault = new wsVault.net.sagepayments.www.wsVault();
vaultReturnDS = sageVault.INSERT_CREDIT_CARD_DATA(M_ID, M_KEY, CARDNUMBER, EXPIRATION_DATE);

The below is the return from sagepayments Vault: the GUID, if successful, and message - in a DataSet.  I could not find an answer to this issue online.  I called Sage and Blytheco and there was no answer there.  There are a couple questions posted to this forum.  I will update them with this link. (of course the below information was using a 'fake' credit card and test vault key and id)
