Calendly to KlickTipp Booking & Cancellation Sync

This workflow integrates Calendly with KlickTipp to automatically process new bookings, cancellations, and reschedules. It captures event details including participant info, converts dates to UNIX timestamps, standardizes phone numbers, and manages invitees and guests dynamically. Guest data is recovered from invitee records during cancellations since Calendly omits it.

Key benefits include reduced manual data entry, accurate subscriber management in KlickTipp, and intelligent handling of reschedules to prevent duplicates. It validates critical fields like emails, phones, and URLs, ensuring reliable API submissions.

Ideal for service-based businesses using Calendly for scheduling and KlickTipp for email marketing/CRM. Use cases: Coaching sessions, webinars, consultations where bookings need instant subscriber updates, cancellations trigger unsubscribes, and guests are tracked individually.
