I found a solution using System.Reflection. I downloaded .Net Reflector
and found the hidden mothod names inside the GatewayRequest class. I
then found a hidden method named "SetApiAction". This internal method
takes the RequestAction Enum as a param...
How would we modify the source to perform a Prior Authorization Capture?
The class library is pre-compiled into the AuthorizeNet.dll. Can you
send a working sample? I'm having the exact same issue. Thanks!
