Can I use other payment sources other than the ones you show?

In other words, can I copy and paste in a link for a payment site that we already use?  We are already set up to receive payments through PushPay.

Since we do not have integration yet with PushPay, even if you add a link to the form from your payment site, it will have no bearing or effect on the submission data.

What I am saying is, if you put the payment details in your form, there is no means for the informaion data to be transferred to your payment site/processor which is PushPay.

You can also send us a request for the form payment integration to PushPay. You can use this link http://www.jotform.com/contact/ to create a separate post for the request.

Hope this help. Let us know how we can be of further assistance.
