We have an integration that is about 6+ yrs old using the url: https://secure.authorize.net/gateway/transact.dll. All the values are passed over the url as querystring variables.
My question is this: are there variable that I can pass the profile & and/or payment ID from the CIM instead of the cc num & exp date?
If so, what are they? If not, what is the latest api call I need that supports using CIM for transaction?
