Someone was trying to run credit cards through our form to hack it.Asked by habitatjackson on March 03, 2016 at 01:08 PM
over the last couple days our form was being used to run different credit cards every minute. They all had the same name. none of them went through but our processing company said we should contact you and there should be a way that we can block them.
Thanks for any info.
Unfortunately, we cannot block someone from accessing your form. However, you can add in unique submissions in order to limit their ability to submit the form:
This would, however, limit other users to a single submission as well.
