I've been using authorize.net's SIM plugin for a few years with no problems, but am trying to set up automatic rebilling now and having some trouble. I have a rebilling option set on the authorize.net form, as well as the relay response code from aMember entered into the authorize.net settings. When a customer buys a subscription the payment goes through, but no evidence of an attempted rebill ever shows up. I also am paying for the ARB service on authorize.net, if that is required. Are there any obvious things I may have missed in the setup, or any other info I could supply to aid someone in helping me? Thanks!
Authorize.SIM plugin doesn't support recurring billing. You should use AuthorizeCIM instead. Btw you don't need to have ARB enabled.
