- Only send lines with quantity ordered greater than zero - Authorize.Net does not handle zero or negative quantity ordered.
- Only send lines with price greater than zero - Authorize.Net does not handle zero or negative prices.
- Only send 30 lines - Authorize.Net does not support more than 30 lines.
