    Although I've tested your form using a testing Credit Card, I got this message: 

    On the Authorize.net developers page shows that the Credit Card number should contain "Between 13 and 16 digits without spaces". 

    The testing Credit Card I'm currently using contains 16 numbers, so I should get a  message saying that the Credit Card number is invalid. 

    Could you please confirm us that this is the same error your customers are getting? 

    If possible, please provide us a screenshot of the exact error they're getting, we will be glad to forward this thread to our developers if needed
