Authorize.net purchase identifiers

Hello,

I am trying to figure out how to set identifiers for authorize.net using the usermanager or hotspot set up in a ccr-1016.

I get an ip address in the purchases and all the authorize.net configuration is working. I just need to be able to differentiate vlans, or hotspot profiles for separate ip ranges (or physical locations) for tracking purchases.

Does anyone out there know how to do this?
