CalDAV

Warning: The CalDAV integration is in an early alpha stage and has bugs. It works well with some clients while having issues with others. If you encounter issues, please report them

Vikunja supports managing tasks via the caldav VTODO extension.

URLs #

All urls are located under the /dav subspace.

Urls are:

  • /principals/<username>/: Returns urls for project discovery. Use this url to initially make connections to new clients.
  • /projects/: Used to manage projects
  • /projects/<Project ID>/: Used to manage a single project
  • /projects/<Project ID>/<Task UID>: Used to manage a task on a project

The whole thing is not optimized at all and probably pretty inefficient.

Request body and headers are logged if the debug output is enabled.
