I need to use authorize.net for my payment gateway. Does BreezingForms support it?
Authorize.net is not yet implemented natively in BreezingForms, but it is relatively simple to add it yourself by using the "End Submit" piece. Basically, you would pass the necessary form variables to authorize.net as described in the Send Field Values to a Different URL Tip.
The fields that authorize.net needs are described in their integration documentation.
