EGroupware CalDAV/CardDAV server and REST API
CalDAV/CardDAV is build on HTTP and WebDAV, implementing the following additional RFCs containing documentation of the protocol:
- rfc4791: CalDAV: Calendaring Extensions to WebDAV
- rfc6638: Scheduling Extensions to CalDAV
- rfc6352: CardDAV: vCard Extensions to WebDAV
- rfc6578: Collection Synchronization for WebDAV
- many additional extensions from former Apple Calendaring Server used by Apple clients and others
Path / URL layout for CalDAV/CardDAV and REST is identical
One can use the following URLs relative (!) to https://example.org/egroupware/groupdav.php
/
base of Cal|Card|GroupDAV tree, only certain clients (KDE, Apple) can autodetect folders from here/principals/
principal-collection-set for WebDAV ACL/principals/users/<username>/
/principals/groups/<groupname>/
/<username>/
users home-set with/<username>/addressbook/
addressbook of user or group given the user has rights to view it/<current-username>/addressbook-<other-username>/
shared addressbooks from other user or group/<current-username>/addressbook-accounts/
all accounts current user has rights to see/<username>/calendar/
calendar of user given the user has rights to view it/<username>/calendar/?download
download whole calendar as .ics file (GET request!)/<current-username>/calendar-<other-username>/
shared calendar from other user or group (only current !)/<username>/inbox/
scheduling inbox of user/<username>/outbox/
scheduling outbox of user/<username>/infolog/
InfoLog's of user given the user has rights to view it/addressbook/
all addressbooks current user has rights to, announced as directory-gateway now/addressbook-accounts/
all accounts current user has rights to see/calendar/
calendar of current user/infolog/
infologs of current user/(resources|locations)/<resource-name>/calendar
calendar of a resource/location, if user has rights to view/<current-username>/(resource|location)-<resource-name>
shared calendar from a resource/location
Shared addressbooks or calendars are only shown in the users home-set, if he subscribed to it via his CalDAV preferences!
Calling one of the above collections with a GET request / regular browser generates an automatic index from the data of a allprop PROPFIND, allow browsing CalDAV/CardDAV tree with a regular browser.
REST API: using EGroupware CalDAV/CardDAV server with JSON
currently implemented only for contacts!
Following RFCs / drafts used/planned for JSON encoding of ressources
- draft-ietf-jmap-jscontact: JSContact: A JSON Representation of Contact Data (* see at end of document)
- draft-ietf-jmap-jscontact-vcard: JSContact: Converting from and to vCard
- rfc8984: JSCalendar: A JSON Representation of Calendar Data
Supported request methods and examples
- GET to collections with an
Accept: application/json
header return all resources (similar to WebDAV PROPFIND)
Example: Getting all entries of a given users addessbook
curl https://example.org/egroupware/groupdav.php/<username>/addressbook/ -H "Accept: application/pretty+json" --user <username>

following GET parameters are supported to customize the returned properties:
- props[]= eg. props[]=getetag to return only the ETAG (multiple DAV properties can be specified) Default for addressbook collections is to only return address-data (JsContact), other collections return all props.
- sync-token= to only request change since last sync-token, like rfc6578 sync-collection REPORT
- nresults=N limit number of responses (only for sync-collection / given sync-token parameter!) this will return a "more-results"=true attribute and a new "sync-token" attribute to query for the next chunk
Example: Getting just ETAGs and displayname of all contacts in a given AB
curl -i 'https://example.org/egroupware/groupdav.php/<username>/addressbook/?props[]=getetag&props[]=displayname' -H "Accept: application/pretty+json" --user <username>
{
"responses": {
"/addressbook/1833": {
"displayname": "Default Tester",
"getetag": "\"1833:24\""
},
"/addressbook/1838": {
"displayname": "Test Tester",
"getetag": "\"1838:19\""
}
}
}
Example: Start using a sync-token to get only changed entries since last sync
Initial request with empty sync-token and only requesting 10 entries per chunk:
curl 'https://example.org/egroupware/groupdav.php/addressbook/?sync-token=&nresults=10&props[]=displayname' -H "Accept: application/pretty+json" --user <username>
{
"responses": {
"/addressbook/2050": "Frau Margot Test-Notifikation",
"/addressbook/2384": "Test Tester",
"/addressbook/5462": "Margot Testgedöns",
"/addressbook/2380": "Frau Test Defaulterin",
"/addressbook/5474": "Noch ein Neuer",
"/addressbook/5575": "Mr New Name",
"/addressbook/5461": "Herr Hugo Kurt Müller Senior",
"/addressbook/5601": "Steve Jobs",
"/addressbook/5603": "Ralf Becker",
"/addressbook/1838": "Test Tester"
},
"more-results": true,
"sync-token": "https://example.org/egroupware/groupdav.php/addressbook/1400867824"
}
Requesting next chunk:
curl 'https://example.org/egroupware/groupdav.php/addressbook/?sync-token=https://example.org/egroupware/groupdav.php/addressbook/1400867824&nresults=10&props[]=displayname' -H "Accept: application/pretty+json" --user <username>
{
"responses": {
"/addressbook/1833": "Default Tester",
"/addressbook/5597": "Neuer Testschnuffi",
"/addressbook/5593": "Muster Max",
"/addressbook/5628": "2. Test Contact",
"/addressbook/5629": "Testen Tester",

},
"more-results": true,
"sync-token": "https://example.org/egroupware/groupdav.php/addressbook/1427103057"
}
Example: Requesting only changes since last sync
sync-token
from last sync need to be specified (note the null for a deleted resource!)
curl 'https://example.org/egroupware/groupdav.php/addressbook/?sync-token=https://example.org/egroupware/groupdav.php/addressbook/1400867824' -H "Accept: application/pretty+json" --user <username>
{
"responses": {
"/addressbook/5597": null,

],
"fullName": "Default Tester",
....
}
},
"sync-token": "https://example.org/egroupware/groupdav.php/addressbook/1427103057"
}
- GET requests with an
Accept: application/json
header can be used to retrieve single resources / JsContact or JsCalendar schema
Example: GET request for a single resource
curl 'https://example.org/egroupware/groupdav.php/addressbook/5593' -H "Accept: application/pretty+json" --user <username>
{
"uid": "5638-8623c4830472a8ede9f9f8b30d435ea4",
"prodId": "EGroupware Addressbook 21.1.001",
"created": "2010-10-21T09:55:42Z",
"updated": "2014-06-02T14:45:24Z",
"name": [
{ "type": "personal", "value": "Default" },
{ "type": "surname", "value": "Tester" }
],
"fullName": "Default Tester",
....
}
- POST requests to collection with a
Content-Type: application/json
header add new entries in addressbook or calendar collections (Location header in response gives URL of new resource)
Example: POST request to create a new resource
cat <<EOF | curl -i 'https://example.org/egroupware/groupdav.php/<username>/addressbook/' -X POST -d @- -H "Content-Type: application/json" --user <username>
{
"uid": "5638-8623c4830472a8ede9f9f8b30d435ea4",
"prodId": "EGroupware Addressbook 21.1.001",
"created": "2010-10-21T09:55:42Z",
"updated": "2014-06-02T14:45:24Z",
"name": [
{ "type": "personal", "value": "Default" },
{ "type": "surname", "value": "Tester" }
],
"fullName": { "value": "Default Tester" },
....

-
PUT requests with a
Content-Type: application/json
header allow modifying single resources -
DELETE requests delete single resources
-
one can use
Accept: application/pretty+json
to receive pretty-printed JSON eg. for debugging and exploring the API
Implemented changes from JsContact draft 08:
- localizedString type / object is removed in favor or regular String type and a localizations object like in JsCalendar
- Vendor-specific Property Extensions and Values
use
<domain-name>:<name>
like in JsCalendar - top-level objects need a
@type
attribute with one of the following values:NameComponent
,Organization
,Title
,Phone
,Resource
,File
,ContactLanguage
,Address
,StreetComponent
,Anniversary
,PersonalInformation
