# EGroupware REST API for Timesheet

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)
- Timesheet application

Following schema is used for JSON encoding of timesheets
* `@type`: `timesheet`
* `id`: integer ID
* `title`: string
* `description`: string (multiple lines)
* `start`: UTCDateTime e.g. `2020-02-03T14:35:37Z`
* `duration`: integer in minutes
* `quantity`: double
* `paused`: integer pause time(s) in minutes
* `project`: string
* `pm_id`: integer ID of ProjectManager app (readonly currently!)
* `unitprice`: double
* `category`: category object with a single(!) category-name e.g. `{"category name": true}`
* `owner`: string with either email or username or integer ID
* `created`: UTCDateTime e.g. `2020-02-03T14:35:37Z`
* `modified`: UTCDateTime e.g. `2020-02-03T14:35:37Z`
* `modifier`: string with either email or username or integer ID
* `pricelist`: integer ID of projectmanager pricelist item
* `status`: string
* `egroupware.org:customfields`: custom-fields object, see other types
* `etag`: string `"<id>:<modified-timestamp>"` (double quotes are part of the etag!)

### Supported request methods and examples

#### **GET** to collections with an `Accept: application/json` header return all timesheets (similar to WebDAV PROPFIND)

        "etag": "140:1471878802"
    },
...
}
```
</details>
       
  Following GET parameters are supported to customize the returned properties:
  - props[]=<DAV-prop-name> eg. props[]=getetag to return only the ETAG (multiple DAV properties can be specified)
    Default for timesheet collections is to only return address-data (JsContact), other collections return all props.
  - sync-token=<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 timesheets of a user:
  - `filters[search]=<pattern>` searches for `<pattern>` in the whole timesheet like the search in the GUI
  - `filters[search][%23<custom-field-name>]=<custom-field-value>` filters by a custom-field value
  - `filters[<attribute-name>]=<value>` filters by a DB-column name and value
