Has anyone successfully used Pardot Form Handlers in concert with Unbounce landing pages?

Hi there - we’re working to make our multiple platforms more integrated and we’d like more control over how we handle leads from Unbounce pages. Pardot forms would allow us to do that. One option is to use an iFrame with a Pardot form on an Unbounce page, but I don’t believe that would be responsive and would eliminate some Unbounce functionality. The other alternative is Form Handlers - I believe this should allow me to fit submitted form information directly to Pardot without a built in Integration with Unbounce.

Has anyone successfully accomplished this and if so - could you outline the steps necessary to take?

Thanks so much!
