Check Availability and Book from WhatsApp
A prospect pings you on WhatsApp asking for time. The agent checks your Cal.com availability, proposes 3 slots, locks the chosen one, and creates the booking with a video link — all inside chat.
Conversation example
Samir just pinged me asking when I'm free this week for a 30 min chat
Checking your Cal.com availability for this week on the 30-min event type...
3 good slots for Samir: - Tue Apr 13 — 14:00 PT - Wed Apr 14 — 10:30 PT - Thu Apr 15 — 16:00 PT Draft to send Samir: 'Hey Samir — got a few options: Tue 2pm, Wed 10:30am, or Thu 4pm PT. Which works?' Send?
Yes, send. Also hold all 3 slots so nothing else books them
Sent the message and placed 30-min holds on all 3 Cal.com slots (tentative event). First slot Samir picks will convert to a real booking; the others auto-release. I'll ping you the moment he replies.

Instant Cal.com Booking Alerts with Attendee Details
Every new Cal.com booking fires a webhook. The agent pulls the attendee info, formats it cleanly, and posts it to the right WhatsApp channel so your team sees every meeting the moment it's scheduled.
Auto-Research Every Prospect Before the Meeting
30 minutes before a Cal.com meeting starts, the agent pulls the attendee's LinkedIn, company site, recent news, and any prior conversations from your CRM — then delivers a 1-page brief to WhatsApp.
Reschedule Cal.com Bookings from WhatsApp
Tell the agent 'move my 3 PM with Samir to Thursday afternoon' and it looks up the booking, checks availability, reschedules in Cal.com, and notifies the attendee — all from one message.
Daily Agenda Compiled from Cal.com
Every morning, the agent reads your Cal.com calendar for the day, merges in Google Calendar events, and delivers a clean agenda to WhatsApp — with the next meeting highlighted.
Auto Follow-Up for No-Show Cal.com Bookings
When a Cal.com meeting ends and the attendee didn't show, the agent drafts a warm, non-pushy follow-up message with a personalized rebooking link and sends it from your WhatsApp.
