Auto Fill Data in Funnel

I have one form in website where use fill all data like First Name, Last Name, Date of Birth then once user click on submit button it will redirect to funnel page, on funnel page all these data should be auto fill.

Can someone guide on this?

Hi @Milan_Pansuriya,
Some custom needs to be added to the website where those users come from.
Could you share a URL to the website your clients come from so that we could provide the most suitable custom code that auto-fills the data in your Funnelish funnel?
