Using Monday to book calendar events with an external link?

Hi everyone - just wanted to know if anyone had any luck setting up a board with an external link (form for instance) in order to set up calendar bookings? Is there a way to send out a form that does not allow bookings of already taken slots?

Let’s say the form was sent out to multiple vendors in order to showcase a demo of a tool, up to 8 vendors. They fill in the form and propose a time and date, but Monday is able to reject or suggest alternative timings to them in a slot is already taken up?

Appreciate your help in advance :slight_smile:
