Which Authorize.net module should I use? in Authorize.net Posted June 15, 2010 I am currently processing cards manually with the Authorize.net virtual terminal. I am mostly an off-line business but lately my web sales have ramped up to point where manual processing is taking way too much time. I assume my best bet is start using one of the Authorize.net AIM modules. There seems to be two major candidates and I am reading here that many shops are having issues with both. Should I start with the Certified version or "Authorize Net AIM module (GPL)"? Ideally I would like to review transactions before capturing. If I set the payment module for authorize only, will I have to manually retype all of the order information before capture or can I just tweak anything that needs to be changed and capture? Thank Vger's add-on was the only one that I could get to work. If you do authorize only, you need to log in to authorize.net and capture (it's a simple click of a couple buttons).
