EGroupware REST API for InfoLog

Authentication is via Basic Auth with username and a password, or a token valid for:

• either just the given user or all users
• CalDAV/CardDAV Sync (REST API)
• InfoLog application

Following RFCs / drafts used/planned for JSON encoding of InfoLog entries

• rfc8984: JSCalendar: A JSON Representation of Calendar Data
• links sub-collection to add attachments and links to other application-entries

Used JSCalendar Task schema to encode InfoLog entries plus EGroupware&InfoLog specific extensions:

• stock JSCalendar Task attributes like: uid, title, start, ... (see above link)
• @type is always Task independent of InfoLog type, see egroupware.org:type below
• progress stock values:
  • needs-action (InfoLog not-started)
  • in-progress (InfoLog ongoing)
  • completed (InfoLog done)
  • cancelled
  • egroupware.org:<infolog-status> (all other status supported by InfoLog use a egroupware.org: prefix)
• participants contains task-owner (role owner), responsible users (role attendee) and CC'ed (role informational)
  • participants is an object with either the numerical user-id or the email address as attribute-name and an object with the following attributes:
  • name of owner, responsible or CC'ed
  • email email-address
  • kind always individual or group for groups (other kinds are NOT supported)
  • roles: are NOT explicitly stored
    • attendee responsible user or group of the task
    • infomational CC'ed email addresses to keep informed / send notifications to
    • owner this is the task owner, which might or might not be also an attendee
  • other attributes like participationStatus are currently NOT persisted by InfoLog
• egroupware.org:type InfoLog type like task, phone, note, email, also custom InfoLog-types admin has created
• egroupware.org:completed completed date&time
• egroupware.org:price float value with price, if set
• egroupware.org:pricelist integer ID of used price-list (readonly)
• egroupware.org:customfields custom-field object, if custom-fields are defined by admin and used in the entry
• relatedTo object with UID of parent-entry as attribute-name and object as value with attributes
  • @type Relation
  • relation and value parent, other relation types are NOT supported
• you can use the links sub-collection of each entry to add relations/links to other application-entries
• InfoLogs primary link can also be created via the links sub-collection with arel of egroupware.org-primary

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 infolog collection

curl https://example.org/egroupware/groupdav.php/<username>/infolog/ -H "Accept: application/pretty+json" --user <username>

}

The 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 calendar collections is to only return calendar-data (JsEvent), 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

The GET parameter filters allows to filter or search for a pattern in InfoLog entries:

• filters[search]=<pattern> searches for <pattern> in the whole contact like the search in the GUI
• filters[search][%23<custom-field-name>]=<custom-field-value> filters by a custom-field value
• filters[<database-column>]=<value> filters by a DB-column name and value

Please note: filters use the database column-names, not JSTask property-names!

Examples: see addressbook

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

POST requests to collection with a Content-Type: application/json header add new entries in infolog collections

(Location header in response gives URL of new resource)

Example: POST request to create a new resource and use "Prefer: return=representation" to get it fully expanded back

RalfsMac:mserver ralf$ cat <<EOF | curl -i 'https://example.org/egroupware/groupdav.php/<username>/infolog/' \

PUT requests with a Content-Type: application/json header allow modifying single resources (requires to specify all attributes!)

Example: PUT request with UID to update an existing resource or create it, if not exists

cat <<EOF | curl -i 'https://example.org/egroupware/groupdav.php/<username>/infolog/1192' -X PUT -d @- -H "Content-Type: application/json" --user <username>

    "created": "2024-05-06T14:25:14Z",
    "title": "Test-Test for Birgit updated",
....
}
EOF

HTTP/1.1 204 No Content

New tast:

HTTP/1.1 201 Created
Location: https://example.org/egroupware/groupdav.php/<username>/infolog/1234

PATCH request with a Content-Type: application/json header allow to modify a single resource by only specifying changed attributes as a PatchObject

Example: PATCH request to modify an event with partial data

cat <<EOF | curl -i 'https://example.org/egroupware/groupdav.php/<username>/infolog/1234' -X PATCH -d @- -H "Content-Type: application/json" --user <username>
{
  "title": "New title"
}
EOF

HTTP/1.1 204 No content

DELETE requests delete single resources

Example: Delete an existing event

Please note: the "Accept: application/json" header is required, as the CalDAV server would return 404 NotFound as the url does NOT end with .ics

curl -i 'https://example.org/egroupware/groupdav.php/<username>/infolog/1234' -X DELETE -H "Accept: application/json" --user <username>

HTTP/1.1 204 No Content

• one can use Accept: application/pretty+json to receive pretty-printed JSON e.g. for debugging and exploring the API
