# 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](https://code.vikunja.io/api/issues/new?body=[caldav])
Vikunja supports managing tasks via the [caldav VTODO](https://tools.ietf.org/html/rfc5545#section-3.6.2) extension.
{{< table_of_contents >}}
## URLs
All urls are located under the `/dav` subspace.
Urls are:
* `/principals/<username>/`: Returns urls for list discovery. *Use this url to initially make connections to new clients.*
* `/lists/`: Used to manage lists
* `/lists/<List ID>/`: Used to manage a single list
* `/lists/<List ID>/<Task UID>`: Used to manage a task on a list
## Supported properties
Vikunja currently supports the following properties:
* `UID`
* `SUMMARY`
* `DESCRIPTION`
* `PRIORITY`
* `COMPLETED`
* `DUE`
* `DTSTART`
* `DURATION`
* `ORGANIZER`
* `RELATED-TO`
* `CREATED`
* `DTSTAMP`
* `LAST-MODIFIED`
Vikunja **currently does not** support these properties:
* `ATTACH`
* `CATEGORIES`
* `CLASS`
* `COMMENT`
* `GEO`
* `LOCATION`
* `PERCENT-COMPLETE`
* `RESOURCES`
* `STATUS`
* `CONTACT`
* `RECURRENCE-ID`
* `URL`
* Recurrence
* `SEQUENCE`
## Tested Clients
### Working
* [Evolution](https://wiki.gnome.org/Apps/Evolution/)
### Not working
* [Tasks (Android)](https://tasks.org/)
## Dev logs
The whole thing is not optimized at all and probably pretty inefficent.
Request body and headers are logged if the debug output is enabled.

And then it just stops.
