HTTP request

PUT https://www.googleapis.com/calendar/v3/calendars/calendarId/events/eventId

Parameters

Parameter name Value Description
Path parameters
calendarId string Calendar identifier. To retrieve calendar IDs call the calendarList.list method. If you want to access the primary calendar of the currently logged in user, use the "primary" keyword.
eventId string Event identifier.
Optional query parameters
alwaysIncludeEmail boolean Whether to always include a value in the email field for the organizer, creator and attendees, even if no real email is available (i.e. a generated, non-working value will be provided). The use of this option is discouraged and should only be used by clients which cannot handle the absence of an email address value in the mentioned places. Optional. The default is False.
conferenceDataVersion integer Version number of conference data supported by the API client. Version 0 assumes no conference data support and ignores conference data in the event's body. Version 1 enables support for copying of ConferenceData as well as for creating new conferences using the createRequest field of conferenceData. The default is 0. Acceptable values are 0 to 1, inclusive.
maxAttendees integer The maximum number of attendees to include in the response. If there are more than the specified number of attendees, only the participant is returned. Optional.
sendNotifications boolean Deprecated. Please use sendUpdates instead.

Whether to send notifications about the event update (for example, description changes, etc.). Note that some emails might still be sent even if you set the value to false. The default is false.
sendUpdates string Guests who should receive notifications about the event update (for example, title changes, etc.).

Acceptable values are:
  • "all": Notifications are sent to all guests.
  • "externalOnly": Notifications are sent to non-Google Calendar guests only.
  • "none": No notifications are sent. This value should only be used for migration use cases (note that in most migration cases the import method should be used).
supportsAttachments boolean Whether API client performing operation supports event attachments. Optional. The default is False.

reminders.overrides[].method string The method used by this reminder. Possible values are:
  • "email" - Reminders are sent via email.
  • "sms" - Deprecated. Once this feature is shutdown, the API will no longer return reminders using this method. Any newly added SMS reminders will be ignored. See Google Calendar SMS notifications to be removed for more information.

start.date date The date, in the format "yyyy-mm-dd", if this is an all-day event. writable
start.dateTime datetime The time, as a combined date-time value (formatted according to RFC3339). A time zone offset is required unless a time zone is explicitly specified in timeZone. writable
start.timeZone string The time zone in which the time is specified. (Formatted as an IANA Time Zone Database name, e.g. "Europe/Zurich".) For recurring events this field is required and specifies the time zone in which the recurrence is expanded. For single events this field is optional and indicates a custom time zone for the event start/end. writable
status string Status of the event. Optional. Possible values are:
  • "confirmed" - The event is confirmed. This is the default status.
  • "tentative" - The event is tentatively confirmed.
  • "cancelled" - The event is cancelled (deleted). The list method returns cancelled events only on incremental sync (when syncToken or updatedMin are specified) or if the showDeleted flag is set to true. The get method always returns them.

    A cancelled status represents two different states depending on the event type:

    1. Cancelled exceptions of an uncancelled recurring event indicate that this instance should no longer be presented to the user. Clients should store these events for the lifetime of the parent recurring event.

      Cancelled exceptions are only guaranteed to have values for the id, recurringEventId and originalStartTime fields populated. The other fields might be empty.

    2. All other cancelled events represent deleted events. Clients should remove their locally synced copies. Such cancelled events will eventually disappear, so do not rely on them being available indefinitely.

      Deleted events are only guaranteed to have the id field populated.

    On the organizer's calendar, cancelled events continue to expose event details (summary, location, etc.) so that they can be restored (undeleted). Similarly, the events to which the user was invited and that they manually removed continue to provide details. However, incremental sync requests with showDeleted set to false will not return these details.

    If an event changes its organizer (for example via the move operation) and the original organizer is not on the attendee list, it will leave behind a cancelled event where only the id field is guaranteed to be populated.

writable
summary string Title of the event. writable
transparency string Whether the event blocks time on the calendar. Optional. Possible values are:
  • "opaque" - Default value. The event does block time on the calendar. This is equivalent to setting Show me as to Busy in the Calendar UI.
  • "transparent" - The event does not block time on the calendar. This is equivalent to setting Show me as to Available in the Calendar UI.
writable
visibility string Visibility of the event. Optional. Possible values are:
  • "default" - Uses the default visibility for events on the calendar. This is the default value.
  • "public" - The event is public and event details are visible to all readers of the calendar.
  • "private" - The event is private and only event attendees may view event details.
  • "confidential" - The event is private. This value is provided for compatibility reasons.
writable
