I've been testing webhooks for CalDAV events and can confirm that CalendarObjectDeletedEvent webhooks do not fire when deleting calendar events via CalDAV DELETE requests. I'm not sure if this warrants a new issue so I'm posting here.
Testing details
- Nextcloud 31 (docker: nextcloud:31-apache)
- webhook_listeners app (bundled)
- Registered webhook for CalendarObjectCreatedEvent, CalendarObjectUpdatedEvent, CalendarObjectDeletedEvent
Results
✅ CalendarObjectCreatedEvent fires correctly
✅ CalendarObjectUpdatedEvent fires correctly
❌ CalendarObjectDeletedEvent never fires
Test procedure
# Created event - webhook fired
curl -X PUT http://nextcloud:password@localhost:8080/remote.php/dav/calendars/admin/personal/test-event.ics \
-H "Content-Type: text/calendar" \
-d 'BEGIN:VCALENDAR...'
# Updated event - webhook fired
curl -X PUT http://nextcloud:password@localhost:8080/remote.php/dav/calendars/admin/personal/test-event.ics \
-H "Content-Type: text/calendar" \
-d 'BEGIN:VCALENDAR...'
# Deleted event - NO webhook fired
curl -X DELETE http://nextcloud:password@localhost:8080/remote.php/dav/calendars/admin/personal/test-event.ics \
-u admin:password
The DELETE request returns 204 No Content (success), but no CalendarObjectDeletedEvent webhook is triggered.
This makes it impossible to track calendar deletions via webhooks for real-time synchronization use cases.
Hi @cbcoutinho
Your post is not related to the original issue, and should have been a new issue.
As per your post, the CalendarObjectDeletedEvent is fired on the second delete. The first delete moves the event to trash, the second delete actually deletes the event.
If you would like to see the flow, open the UI with dev tools open and watch the communication in the network tab.
Hi @SebastianKrupinski, my apologies for resurfacing this old ticket and the misunderstanding of how the Trash bin works regarding webhook delivery.
Thanks for the tip about using dev tools 👍
