using remote payment with Authorize.net
I am trying to setup a site with PowerStore 4.0 using Authorize.net and wish to use Authorize.net's remote payment feature SIM (simple integration method).
When I specify Authorize.net on the gateway setup, I do not have any option for local (Advanced Integration Method [AIM]) vs. SIM. In addition, the checkout page includes credit card information, so I am assuming the default setup is for AuthNet's Advanced Integration Method.
What changes do I need to make to enable my PowerStore site to use AuthNet's SIM (remote checkout) process?
(In an effort to "cover my bases", I also submitted a paid support incident ticket for this.)
