I'm completely lost on authorize.net. Our auth.net provider says I enter all the VAR setup data in eCart. I've watched the YouTube video. I've read the web page help, copied it to a document and I'm not seeing where to enter all that information. What am I missing?
Is it on the authorize.net side of things where stuff like merchant number, acquirer bank number, Visa/MC, Discover, Amex account numbers, etc is setup? Or is there something on eCart that I'm missing?
