CRM Stage Move After Calendar Booking

A calendar booking automatically advances the matching CRM opportunity to the right stage and notes the appointment, so the pipeline reflects reality the moment a call is booked instead of after manual updates.

Problem

The operating gap

A lead books a call but the CRM still shows them in an earlier stage until someone updates it by hand. Reporting is wrong, follow-up automations fire on stale stages, and reschedules or cancellations never make it back into the record.

Build

What gets built

A Cal.com booking webhook is signature-verified, matched to the CRM opportunity by a stored submission ID or email, and moves the stage to 'Call Booked' with the appointment time logged as a note. Reschedule and cancellation events update the same record so the stage stays truthful, and bookings that can't be matched to an opportunity route to a review task rather than creating an orphan. The result is a pipeline whose stages track actual booking state automatically.
