Host a webinar or Group Discussion (GD) where many people book into one shared time slot. In Cal ID, you combine the Offer seats feature with specific availability rules so a single session can hold a whole group — and no other days or times distract the booker.

Why use this setup?

  • Host large groups: Allow multiple attendees to join a single session at once.
  • Lock in a specific time: Ensure the event only happens when you want it to, without showing other daily availability.
  • Control attendance: Set a maximum capacity for your webinar or discussion.

How to set it up

A locked group event comes from three settings working together: Offer seats (capacity), Limit future bookings (the date), and a Date Override (the exact time). Set all three and every booking funnels into one slot.

Pick the date

1

4

Add more slots (optional)

If you want to host multiple sessions on the same day (for example, one at 10:00 AM and another at 4:00 PM), set the Date Override accordingly by adding multiple time ranges for that date.

Save

Click Save.

How it works & looks for the booker

  • Limited calendar view: When the booker opens your link, they will see most dates “greyed out”. Only the specific date(s) you chose in Limit future bookings will be clickable.
  • Specific time slots: After selecting the date, the booker will see only the specific time slots you created via the Date Override (e.g., 10:00 AM or 4:00 PM).
  • Seat availability: The booking page may show how many seats are remaining, helping to create a sense of urgency for the event.
  • Confirmation: Once they book, they receive a confirmation for that exact time, and the “seat count” for that slot automatically decreases by one.

Funnelling everyone into one slot

Webinar setup: These three settings together create a “locked” event. Because you selected a date range in Limit future bookings and set a Date Override for the time, all available seats funnel into that one slot. Your event is now fixed to a single date and time, so everyone joins at once.
