Keap and Automate Hero


I hope you are all well.

I need help with integrating keap and automate hero. So I made a landing page on keap and added an opt-in form i now want that when someone opts-in their unique deadline should start, this happens using automate hero but for it to work they require keap to allow information to be passed on to automate hero. How can i do that?

Any help will be highly appreciated.

Kind regards
