We are really having an issue. We are using WHMCS and our Merchant Provider is Chase, the have provided us with an AuthNET account however WHMCS does not support AuthNET for VerifiedByVisa or MasterCard SecureCode.... WHMCS said that we need to use the Quantum Gateway the Quantum gateway is apparently made by a company that offers merchant accounts by the name of cdgcommerce.com and they are telling me you cannot use there gateway without having there merchant account.
I think that I see where some of the confusion may be on this. The bottom line is that for any merchant to be able to use a 3rd party application (like WHMCS), both the payment gateway and the 3rd party app must support the gateway's specific API that implements VBV/MSC (if the gateway offers it).
So in the example of Authorize.Net or Payflow Pro, while both of the gateways do have an option for VBV/MSC that does not mean that VBV/MSC will automatically work with any given 3rd party app. The 3rd party app itself will need to support that gateway's implementation of VBV/MSC as well.
Regarding the Quantum Gateway, yes - that definitely supports VBV/MSC and is compatible with WHMCS and many other billing systems.
