I seem to be experiencing an AVS Mismatch error with Authorize.net when dealing with foreign registrants. I believe the issue stems from the "Zip Code" entry, as they do not use US zipcodes. Is there a way to compensate for this? I understand this may not be a Payment Form issue, but was wondering if there is a possible solution. Thanks.
After speaking with a rep from authorize.net this is a setting you change in Authorize.net under their account AVS settings, you uncheck the last 3 boxes for AVS stuff. in case anybody else searches for this.
