My integration with accept.js hosted form is working, but I'm unsure how to set which fields are required in the authorize.net modal popup.
For example, how to I require First/Last Name and Card Code?
The only solution I've found is to go into your Authorize.net Payment Form - Fields settings and require the relevant fields.
This will not enforce a required field on the UI form, however. It will just fail transactions that do not have the required values. Far from perfect -- let me know if there's a better solution.
