Overview
This node interacts with CalDAV servers to manage calendar events, specifically allowing users to update existing events in a selected calendar. It is useful for automating calendar management tasks such as modifying event details without manually accessing the calendar application.
Typical use cases include:
- Updating event titles, descriptions, or locations based on external triggers.
- Changing event start and end times programmatically.
- Marking events as all-day or adjusting their timing dynamically.
For example, you could use this node to automatically update meeting details when a related CRM record changes or to adjust event times based on timezone conversions.
