Any idea when ConvertKit integration will be done?

We currently do not have a direct integration for ConvertKit, so I have forwarded your message as a feature request to our developers. When or if such an integration is implemented, we will make sure to let you know through this support thread.

In the meantime, we do support integration with a third-party service called Zapier, who can then connect submissions from JotForm forms with your ConvertKit account:

I believe the following Zap would be the one to use:
