Authorize.net test integration returns error 'Error 33: Phone is required.'

Hi,

I have setup a couple of authorize.net payment forms, put in the API and transaction key info (and double checked that it was correct.

When I test integration i get the following error message:

"Error 33: Phone is required."

I have looked through documentation and the support area, but could not find any information about this error and how to fix it.

Thank you.

To fix this, you need to do it in your Authorize.Net account.

Please try the following:

1. Login to the Authorize.net Merchant Interface ( at https://secure.authorize.net ),

2. Click on Settings >>Payment Form >> Form Fields and uncheck the Required box for the phone number (also, uncheck the e-mail if it requires the e-mail address as well).

Hope this will help. Let us know if you need further assistance.
