Kalender

Jede Operation in dieser Gruppe: was sie annimmt, was sie zurückgibt und mit welchen Fehlern sie antworten kann.

Operationen

Events and invitations, as the Calendar page of the app shows them: list a window, read an event or the one a thread carries, put events on the calendar and change them, call off a meeting, and answer an invitation. A change that invites, updates or cancels attendees, and every answer, goes out by email, so it also needs emails:send.

GET/calendar/events

List occurrences in a window

Geltungsbereichecalendar:readLiest

from and to are REQUIRED. Occurrences are expanded from recurrence rules, so a calendar has no meaningful unbounded listing. A default window would turn an infinite series into a question with no answer. At most a year apart.

Requires the calendar:read scope.

Query-Parameter

fromstringErforderlich

Start of the window.

Formatdate-time
tostringErforderlich

End of the window, after from and at most 366 days later.

Formatdate-time
timezonestringErforderlich

IANA zone. Decides what an all-day event means.

limitinteger

Rows per page, 1 to 100.

Mindestens 1Höchstens 100Standard25
cursorstring

The previous page's nextCursor, passed back as it came. It is opaque: it holds where the last row sat in this list's order, so a row deleted or edited between pages never breaks the walk, and the next page starts at the first row that sorts after it. A value this list did not hand out is a 400 invalid_cursor.

Rückgabe

200

A page of occurrences, sorted by start and then by event id, with hasMore and nextCursor. Send the same from, to and timezone with every cursor. Nothing in the window is dropped: a series repeats at most once a day, so it gives at most one occurrence per day of the window, and every one is reachable through the pages. The cursor holds the start and event id of the last row, so an event deleted or moved between pages never breaks the walk.

POST/calendar/events

Create an event

Geltungsbereichecalendar:writeSendet E-Mails

Puts an event on the calendar, as New event on the Calendar page of the app does. start and end are ISO 8601 with a zone, and timezone is the IANA zone the event belongs to, UTC unless you say. recurrence takes an RRULE such as FREQ=WEEKLY;BYDAY=MO, and reminders the minutes before the start.

With attendees, an invitation goes to each of them from the address in from, which has to be one the key or app may send as, so the call also needs emails:send. sendInvites: false keeps the change to your own calendar.

Requires the calendar:write scope.

DELETE/calendar/events/{id}

Remove an event

Geltungsbereichecalendar:writeLöscht

Removes an event from the calendar for good, as Remove does in the app. Nobody else is told: to call off a meeting with others in it, use POST /calendar/events/{id}/cancel.

Requires the calendar:write scope.

Pfadparameter

idstringErforderlich

The event id from GET /calendar/events.

Rückgabe

GET/calendar/events/{id}/ics

The event as an .ics document

Geltungsbereichecalendar:readLiest

Served as text/calendar with NO METHOD parameter. A METHOD makes a document actionable (a client seeing method=REQUEST draws accept/decline and can reply to the organiser), and this endpoint has no authority to invite anybody on the workspace behalf. It states what the event currently is.

Requires the calendar:read scope.

Pfadparameter

idstringErforderlich

Event id, the eventId of an occurrence.

Rückgabe

POST/calendar/events/{id}/cancel

Cancel a meeting

Geltungsbereichecalendar:writeSendet E-Mails

Calls off a meeting you organise, as Cancel meeting does in the app. It stays on the calendar with status CANCELLED, and everyone invited is told it is off, from the address in from, so a meeting with attendees also needs emails:send. The body is optional.

Requires the calendar:write scope.

Pfadparameter

idstringErforderlich

The event id from GET /calendar/events.

Request-Body

fromstring

The address the cancellation comes from. It has to be one the key may send as.

POST/calendar/events/{id}/respond

Answer an invitation

Geltungsbereichecalendar:writeemails:sendSendet E-Mails

Accepts, declines or tentatively accepts an invitation, as the buttons of an invitation in the app do. The answer goes to the organiser by email from the invited address the key or app may send as, or from respondingAs when the invitation went to more than one of yours.

Requires the calendar:write and emails:send scopes.

Pfadparameter

The event id from GET /calendar/events.

The event a thread carries

Geltungsbereichecalendar:readLiest

The calendar event that came with an invitation in the thread, as the invitation card of the reading pane shows it. A thread with no event, or one the key or app does not reach, is a 404. Answer it with POST /calendar/events/{id}/respond.

Requires the calendar:read scope.

Pfadparameter
