What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Currently that is not one of the available integrations, all of our available integrations can be seen here http://apps.jotform.com/category/payment_processing
I will forward your request to our development team to see if this is something they are interested in adding. I cannot guarantee if or when they will be able to address this, though if they do decide to add this at some point, they will update this thread.
Do let us know if you have any further questions.
