Run bookings, prep, and follow-ups on Cal.com from a WhatsApp chat
Cal.com is the open-source alternative to Calendly — self-hostable, extensible, and packed with routing forms, workflows, and teams features. The LunoGen Cal.com integration connects your agent to the Cal.com API v2 and webhooks so you can listen for bookings, prep for meetings, reschedule from chat, and follow up with no-shows — all from WhatsApp.
Bookings are a funnel, not a calendar event. Every new Cal.com booking is a chance to research the prospect, prep the right talking points, send a warm pre-meeting note, and automatically follow up after. LunoGen plugs into Cal.com and wraps every booking with agent-driven prep and follow-through — without anyone on your team lifting a finger.
In your Cal.com settings, go to Developer → API keys and create a new key with a friendly name like 'LunoGen Agent'.
Open Credentials → New → Cal.com and paste your API key. Pick the default username or team the agent should work with.
In Cal.com Settings → Developer → Webhooks, add your LunoGen webhook URL and subscribe to BOOKING_CREATED, BOOKING_RESCHEDULED, BOOKING_CANCELLED, and MEETING_ENDED.
Tell the agent which event types to track (e.g. 'Discovery Call', 'Onboarding'). You can set different post-booking workflows per event type.
Create a test booking from a Cal.com link and watch the agent prep and post it to your WhatsApp.
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.
New Cal.com booking. Parsing the payload...
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.

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.

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.

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.

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.
