If you wish to offer availability for just one type of meeting, say "30 min Consultation" you can do so as well. Follow these steps:

Step 1: Go to "Appointment Booking".

Step 2: Click on "Edit Appointment Types" on a Booking Page of your choice.

Step 4: (If you are testing yourself) Propose an appointment with yourself.

This is your booking page. It lists that appointment type that you have made available to your guests. Click on the type of appointment that you wish to book and propose meeting.

This is automated scheduling hence times are determined automatically based on events on your calendar and your setting in Appointment Type.

Step 5: Accept the proposal.
