Using Authorize.net servers instead of current host's

[frodojrr]

We currently use Authorize.net as our gateway. Was told that ShopSite can be integrated to use Authorize.net servers instead of our current host's servers through the Server Integration method (SIM).

I found this: http://developer.authorize.net/api/sim/

Then this:

https://developer.authorize.net/integration/fifteenminutes/#hosted

Am I looking at the right place? If so, which file should I edit in ShopSite?

Site is here: http://www.hhhincorporated.com, currently hosted with Verio.

Thank you!

Authorize.net's SIM method was integrated into ShopSite 10 sp1. If you have that version or a later version then all you need to do is go to Commerce Setup > Payment, Select the Authorize.net SIM method and configure the settings for your account. If you have ShopSite 10 or 10 rX where X is some number or version 9 or earlier then you would need to upgrade to at least ShopSite 10sp1 inorder to be able to use the feature. There is no way that you can integrate it into ShopSite yourself.
