Event type
Keep Cal.com as the source of booking rules.
Choose the event type that owns the duration, availability, host routing, and booking constraints. Waaru uses that configuration rather than maintaining a second scheduling rule set.
Active integration
Connect Cal.com and choose the event type for the journey.
Production setup still needs account authorization, field mapping, host-routing review, and one representative booking test.
Cal.com integration
Book Cal.com appointments through WhatsApp.
Use the event type, availability rules, and required attendee fields your team already manages. The booking result remains part of the conversation so confirmation and follow-up do not start from zero.
In one line
Connect one Cal.com event type to show its available times, collect the required attendee details, create the booking, and use the confirmed result in the next workflow step.

Route the booking before you show the time.
The selected event type determines the host, duration, availability, and attendee questions. The workflow carries that context through confirmation.

Selected booking lifecycle events can continue confirmation, reminder, assignment, or handoff steps.
- Setup
Authorize the account, choose the event type, map required attendee fields, review host routing, and test booking changes.
- Exclusions
The journey does not replace Cal.com's event-type, host, availability, timezone, cancellation, or rescheduling rules.
- Recovery
Test a new booking, reschedule, cancellation, and the exception paths for the exact event type used in production.

Customer journey
Collect the details before creating the booking.
Ask the required attendee questions in the conversation or a WhatsApp Flow. Map only the fields the event type requires, then show available times and create the confirmed booking.
Follow-up
Use the booking result in the next operational step.
Carry the booking reference, time, event type, and outcome into confirmation, reminder, assignment, or team handoff steps. The customer does not need to repeat the appointment context.
Setup boundary
Test the event type your operation will actually use.
Availability, required fields, host routing, timezone handling, cancellation, and rescheduling rules can differ by event type and Cal.com account. Verify one representative new booking and one change before production traffic.
FAQ
Frequently asked questions.
Can a customer book a Cal.com slot from a WhatsApp journey?
Yes. Connect an event type, collect its required attendee details, offer its available times, and create the confirmed booking from the journey.
Does Waaru replace the event type's availability rules?
No. Cal.com remains the source of duration, availability, host routing, and event-type constraints.
Can a WhatsApp Flow collect intake details first?
Yes. Collect the required fields in a WhatsApp Flow or conversation, then pass the mapped answers into the booking step.
Can a confirmed booking continue a workflow?
Yes. Use its reference, time, event type, and outcome in confirmation, reminder, assignment, or handoff steps.
What should be tested before launch?
Verify event-type authorization, required attendee fields, timezone handling, host routing, a new booking, and the change paths your operation will offer.
