We do not have any integration with swipe yet so it is not possible with Jotform. May I also clarify about which swipe service are you referring to? Can you give the website URL so we can check it here? We'll see if we can come up a workaround, if not, we can forward it as a feature request.
We'll be looking forward to your reply.
