Hi All. So far I'm off to a decent start getting the Authorize.net CIM and Amember working together. Had about 20 signups go through no problem. The issue I'm now having is with people trying to sign up using DEBIT/CHECK cards. The test .01 cent transaction gets approved, but the full amount then fails - error 27. Credit Cards are working fine, just not debit cards. Authorize.net says they support credit and debit cards, so I'm not sure what's going on. Could it be the CCV field? That seems to be on in Amember by default, but debit cards don't have those. Anyone know how I can get around this to accept both credit and debit cards?
