Synchronize events & attendees between KlickTipp and Google Calendar

 Community Node Disclaimer: This workflow uses KlickTipp community nodes.

Introduction This workflow creates a complete two-way synchronization between KlickTipp and Google Calendar. When a contact in KlickTipp is tagged, an event is automatically created in Google Calendar. If event status changes or if attendees respond, their RSVP status and event status are reflected in KlickTipp — keeping your contact database, campaigns, and event insights always up to date.

Perfect for marketers, coaches, or event organizers who want to automatically send event invites and instantly capture participation status without manual updates.

How it works Google Calendar → KlickTipp: This template keeps your KlickTipp list in sync with Google Calendar across the full event lifecycle. For every incoming event, the workflow follows these steps:

1. Watch Google Calendar events - Listens for: - Event Created - Event Updated - Event Cancelled

2. Iterate through attendees - Each attendee is handled as a separate item. - This ensures accurate contact updates and tagging even for large events or webinars.

3. Filter attendees (optional) - Attendees from internal or excluded email domains can be filtered out before any processing.

4. Check if the attendee already exists in KlickTipp - If the contact exists → update the contact. - If the contact does not exist → subscribe the contact (with Single or Double Opt-In, depending on action).
