My customers hate the dd/mm/yyyy format. So we followed the Konakart procedure to change it to mm/dd/yyyy. All worked well in KonaKart and the changes were Universal. But When we changed it, Authorize.net API began denying transactions witha credit card expired on all credit cards. As soon as we changed it back it started working. Somewhwre along the line the algorithm is not being passed correctly. Has anyone else encountered this error?
Any help would be appreciated. ???
Sorry meant stops. Fat fingered that one. ::)
I've never seen that problem reported. What you should do is to turn on debugging for AuthorizenetAction.java and BaseGatewayAction.java to look at the data that is posted to Authorizenet. You have the source code for both of these classes.
