client.Calendar

Every method in this namespace: its signature, its parameters, what it returns and an example.

Methods

Calendar events found in mail or put on the calendar here, expanded into occurrences, with invitations, changes, cancellations and answers sent by email.

`Calendar.ListEventsAsync`

List one page of event occurrences inside a time window

calendar:readPages through results

Signature

Task<Page> ListEventsAsync(    DateTimeOffset from,    DateTimeOffset to,    string? timezone = null,    bool? includeTeam = null,    string? q = null,    int? limit = null,    string? cursor = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Expands your events into their occurrences between from and to and returns one page of them, sorted by start time and then by event id. A recurring series gives one row per instance in the window, with its excluded dates left out, and every row points back to its event through eventId. The window is required because a repeating series has no end to list up to. Follow nextCursor while hasMore is true, with the same from, to and timezone:, to read every occurrence, or let ListAllEventsAsync and IterateEventsAsync do that walk.

to must be after from and at most 366 days later. A missing from or to is a 422 invalid_parameter, while a value that does not parse, a reversed or overlong window, or an unknown zone is a 400 invalid_parameter naming the field. Both bounds take a DateTimeOffset or an ISO 8601 string, and the SDK sends a DateTimeOffset as an ISO 8601 instant in UTC.

timezone is an IANA zone and defaults to UTC on the server. It is used to expand any event stored without a zone of its own, which is what decides the day an all day event lands on.

Parameters

fromDateTimeOffsetRequired: Start of the window.
toDateTimeOffsetRequired: End of the window, after from and at most 366 days later.
timezonestring?: IANA zone such as Europe/London, at most 64 characters. Defaults to UTC.
includeTeambool?: true adds the events of the rest of the workspace, apart from the ones marked private. Only a key of the workspace owner sees more with it. Defaults to false.
qstring?: Words to look for in the title, the place and the organiser, at most 200 characters. Only events that hold every word come back, so pass a long window to find an event by name.
limitint?: Occurrences per page, a whole number from 1 to 100. The server defaults to 25.
cursorstring?: The nextCursor of the previous page, sent with the same window. It is opaque, so never build one yourself.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A Page of occurrence objects with items, hasMore and nextCursor. Each item has eventId, uid, start, end, allDay, summary, location, status, transparency, isOrganizer, organizerEmail, recurring, myPartstat and attendeeCount.

Example

var today = new DateTimeOffset(DateTime.UtcNow.Date, TimeSpan.Zero); var page = await client.Calendar.ListEventsAsync(today, today.AddDays(7), timezone: "Europe/London", limit: 50); foreach (var occurrence in page){    Console.WriteLine($"{occurrence["start"]} {occurrence["summary"]} {occurrence["myPartstat"]?.ToString() ?? "not invited"}");} if (page.HasMore){    Console.WriteLine($"More from cursor {page.NextCursor}");}

Notes

The list holds your own events: the ones you made and the ones an address of yours organises or attends. For the workspace owner and their keys, an address counts as theirs unless it was given to a teammate, and includeTeam: true adds the rest of the workspace, apart from events somebody marked private. A member's app and a narrowed key always get their own view.
myPartstat is the response recorded for one of your own addresses, or for the addresses a narrowed key covers, and null when none of them is an attendee.
A narrowed key only sees occurrences whose organiser is one of the addresses it covers or where one of them is an attendee.
Cancelled events are not filtered out. Check status for CANCELLED.
Nothing in the window is dropped. A series repeats at most once a day, so one series gives at most one row per day of the window, and every one of them is reachable through the pages.
The cursor holds the start time and event id of the last row, so an event deleted or moved between pages never breaks the walk. A cursor this list did not hand out is a 400 invalid_cursor.

`Calendar.ListAllEventsAsync`

Collect every occurrence inside a time window into one object

calendar:readPages through results

Signature

Task<IReadOnlyList<JsonObject>> ListAllEventsAsync(    DateTimeOffset from,    DateTimeOffset to,    string? timezone = null,    bool? includeTeam = null,    string? q = null,    int? limit = null,    string? cursor = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Walks every page of ListEventsAsync for one window and returns all of its occurrences, sorted by start time and then by event id. It follows nextCursor until hasMore is false, sending the same from, to and timezone: with each request.

A window of up to 366 days of a busy calendar can hold thousands of occurrences, so prefer IterateEventsAsync when you can stop early.

Parameters

fromDateTimeOffsetRequired: Start of the window.
toDateTimeOffsetRequired: End of the window, after from and at most 366 days later.
timezonestring?: IANA zone such as Europe/London, at most 64 characters. Defaults to UTC.
includeTeambool?: true adds the events of the rest of the workspace, apart from the ones marked private. Only a key of the workspace owner sees more with it. Defaults to false.
qstring?: Words to look for in the title, the place and the organiser, at most 200 characters. Only events that hold every word come back, so pass a long window to find an event by name.
limitint?: Page size for each request, 1 to 100. The server defaults to 25.
cursorstring?: Starts the walk from this cursor instead of the start of the window.
apiKeystring?: Overrides the client API key for every page of this walk.
cancellationTokenCancellationToken: Cancels the request.

Returns

A list of occurrence objects holding every occurrence in the window, earliest first.

Example

using Nextmail.Constants; var occurrences = await client.Calendar.ListAllEventsAsync(DateTimeOffset.Parse("2026-10-01T00:00:00Z"), DateTimeOffset.Parse("2026-11-01T00:00:00Z"), limit: 100); foreach (var occurrence in occurrences){    if ((string?)occurrence["transparency"] == CalendarTransparencies.Opaque)    {        Console.WriteLine($"Busy {occurrence["start"]} to {occurrence["end"]}");    }}

Notes

If any page fails the call throws and the occurrences already fetched are discarded.

`Calendar.IterateEventsAsync`

Stream the occurrences inside a time window one at a time

calendar:readPages through results

Signature

IAsyncEnumerable<JsonObject> IterateEventsAsync(    DateTimeOffset from,    DateTimeOffset to,    string? timezone = null,    bool? includeTeam = null,    string? q = null,    int? limit = null,    string? cursor = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Returns an IAsyncEnumerable<JsonObject> over the occurrences in one window that yields them individually, earliest first, and fetches the next page only when the current one is drained. Nothing is requested until you consume it, and breaking out of the loop stops further requests, which makes it the way to find the next free slot or the next meeting without reading the whole window.

The walk ends when hasMore is false, when a page carries no nextCursor, or when the server repeats a cursor.

Parameters

fromDateTimeOffsetRequired: Start of the window.
toDateTimeOffsetRequired: End of the window, after from and at most 366 days later.
timezonestring?: IANA zone such as Europe/London, at most 64 characters. Defaults to UTC.
includeTeambool?: true adds the events of the rest of the workspace, apart from the ones marked private. Only a key of the workspace owner sees more with it. Defaults to false.
qstring?: Words to look for in the title, the place and the organiser, at most 200 characters. Only events that hold every word come back, so pass a long window to find an event by name.
limitint?: Page size per request, 1 to 100. The server defaults to 25.
cursorstring?: Starts the walk from this cursor instead of the start of the window.
apiKeystring?: Overrides the client API key for every page of this walk.
cancellationTokenCancellationToken: Cancels the request.

Returns

An IAsyncEnumerable<JsonObject> that yields one occurrence per step.

Example

var from = DateTimeOffset.UtcNow;var to = DateTimeOffset.UtcNow.AddDays(30); await foreach (var occurrence in client.Calendar.IterateEventsAsync(from, to)){    if (occurrence["myPartstat"] is not null)    {        Console.WriteLine($"Next meeting: {occurrence["start"]} {occurrence["summary"]}");         break;    }}

Notes

A page request that fails throws out of the foreach loop, after every occurrence of the pages before it has been yielded.

`Calendar.GetEventAsync`

Read an event with its attendees

calendar:read

Signature

Task<JsonObject> GetEventAsync(    string id,    string? apiKey = null,    CancellationToken cancellationToken = default)

Returns a stored event with its attendees and their responses. What the server understood from the iCalendar data is structured here: recurrence holds the RRULE text, exdates the excluded instances, organizer the organiser and alarms the reminders, each an object with minutesBefore and action. The raw iCalendar source is not included, and GetEventIcsAsync serves the event as a document.

id is the event id, the eventId on an occurrence, and not the iCalendar uid. A recurring series is one event however many occurrences it has, so start and end describe its first instance. messageId and threadId link the event to mail in the mailbox when there is any.

Attendees come back in the order they were added, each with partstat, role, rsvp, cutype and respondedAt. A narrowed key gets a 404 unless one of the addresses it covers organises the event or is on the attendee list, and a key that holds a whole domain covers every address on it.

Parameters

idstringRequired: Event id, the eventId of an occurrence, such as cal_ followed by 24 hex characters.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A JsonObject with id, uid, sequence, summary, description, location, url, start, end, allDay, timezone, recurrence, exdates, status, transparency, visibility, organizer, isOrganizer, source, messageId, threadId, alarms, attendees, createdAt and updatedAt.

Example

var entry = await client.Calendar.GetEventAsync("cal_3f9a1c7e5b2d48a06c1e9f4b"); Console.WriteLine($"{entry["summary"]}, {entry["recurrence"]?.ToString() ?? "one off"}"); foreach (var attendee in entry["attendees"]?.AsArray() ?? []){    Console.WriteLine($"{attendee?["email"]}: {attendee?["partstat"]}");}

Notes

status, transparency and visibility carry iCalendar values, and default to CONFIRMED, OPAQUE and PUBLIC.
An attendee's partstat defaults to NEEDS-ACTION and role to REQ-PARTICIPANT until a response is recorded.

`Calendar.GetEventIcsAsync`

Download an event as an iCalendar document

calendar:read

Signature

Task<string> GetEventIcsAsync(    string id,    string? apiKey = null,    CancellationToken cancellationToken = default)

Returns the event serialised as an .ics document, as a raw string rather than parsed JSON. The server sends it as text/calendar; charset=utf-8 with a download filename built from the event's uid, and the SDK requests that type and returns the body untouched.

The document declares METHOD:PUBLISH, and the content type carries no method parameter. That is deliberate: a REQUEST document makes a calendar client offer accept and decline and reply to the organiser, and this endpoint has no authority to invite anyone. Import it to show what the event currently is, not to send an invitation.

It holds one VEVENT with the attendees and their participation status, the recurrence rule, excluded dates and alarms. Lines end in CRLF and long lines are folded. DTSTAMP is the time of the request, so two downloads of an unchanged event differ on that line.

Parameters

idstringRequired: Event id, the eventId of an occurrence.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A string, the iCalendar text from BEGIN:VCALENDAR to END:VCALENDAR.

Example

var ics = (await client.Calendar.GetEventIcsAsync("cal_8d3f0a2b9c4e41f7a6b5c2d1")); Console.WriteLine(ics);

Notes

Errors still come back as JSON and throw NextmailApiException, so a failure never comes back as a string.
Timed events are written in the zone they were created in, as local times with a TZID and a VTIMEZONE that carries the rules of that zone, and all day events as DATE values.
A narrowed key gets a 404 on the same terms as GetEventAsync.

CLI: openemail calendar get-event-ics

`Calendar.CreateEventAsync`

Put an event on the calendar

calendar:write

Signature

Task<JsonObject> CreateEventAsync(    IReadOnlyDictionary<string, object?> body,    string? apiKey = null,    CancellationToken cancellationToken = default)

Creates an event, as New event on the Calendar page of the app does. start and end take a DateTimeOffset or ISO 8601 with a zone, and the SDK sends a DateTimeOffset as a UTC instant. timezone is the IANA zone the event belongs to, which decides what an all-day event means.

With attendees, an invitation goes to each of them by email from from, which has to be an address the key may send as, so the call also needs emails:send. Send ["sendInvites"] = false to keep it to your own calendar.

Parameters

summarystringRequired: The title, 1 to 255 characters.
startDateTimeOffset or stringRequired: When it starts, a DateTimeOffset or ISO 8601 with a zone. A DateTimeOffset is sent as an instant in UTC.
endDateTimeOffset or stringRequired: When it ends, after start and at most two years later.
descriptionstring: Notes about the event, up to 8,000 characters.
locationstring: Where it is: a room, an address or a link.
urlstring: A link that belongs to the event.
meetingUrlstring: The link to the video call, such as a Zoom, Meet or Teams address. The invitation carries it, so guests get a Join button in their calendar too.
allDaybool: Whether it fills whole days. start and end then mark the days.
timezonestring: The IANA zone the event belongs to, UTC unless you say.
recurrencestring: An RRULE such as FREQ=WEEKLY;BYDAY=MO when it repeats.
attendeeslist: Up to 200 people to invite, each a dictionary with email and, if you like, name and optional.
reminderslist: Up to five reminders, each a dictionary with minutesBefore and, if you like, action (DISPLAY, EMAIL or AUDIO, as in Nextmail\Constants\CalendarReminderActions).
transparencystring: OPAQUE shows you busy and TRANSPARENT free, as in Nextmail\Constants\CalendarTransparencies.
visibilitystring: PUBLIC, PRIVATE or CONFIDENTIAL, as in Nextmail\Constants\CalendarVisibilities.
sendInvitesbool: False keeps the change to your own calendar, and sends nothing.
fromstring: The address the invitations come from. It has to be one the key may send as.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A JsonObject for the new event, shaped like the one Calendar.GetEventAsync returns, with its attendees and their responses.

Example

var entry = await client.Calendar.CreateEventAsync(new Body{    ["summary"] = "Planning",    ["start"] = DateTimeOffset.Parse("2026-10-12 09:00Z"),    ["end"] = DateTimeOffset.Parse("2026-10-12 09:30Z"),    ["timezone"] = "Europe/London",    ["attendees"] = new[] { new Body { ["email"] = "[email protected]", ["name"] = "Ada Lovelace" } },    ["reminders"] = new[] { new Body { ["minutesBefore"] = 10 } },    ["from"] = "[email protected]",}); Console.WriteLine($"{entry["id"]} {entry["start"]}");

Notes

The SDK does not retry it, because a second call makes a second event and invites everybody again.
A key that may not send as from is refused with 403 from_address_forbidden, and an event with attendees and no from with 422 invalid_parameter. Invitations without emails:send are a 403 insufficient_scope.

`Calendar.UpdateEventAsync`

Change an event

calendar:write

Signature

Task<JsonObject> UpdateEventAsync(    string id,    IReadOnlyDictionary<string, object?> patch,    string? apiKey = null,    CancellationToken cancellationToken = default)

Changes an event you organise. A field you leave out keeps its value, and attendees replaces the whole list. Everyone invited gets the updated invitation by email from from, so a change to an event with attendees needs emails:send too, unless sendInvites is false.

For a repeating event, scope says which dates change, as the app asks when you edit one date: occurrence changes only the date that starts at occurrenceStart, following that date and every one after it, and series all of them. With following the later dates become a new series with its own id, which is what comes back, and the old one ends the day before.

Parameters

idstringRequired: Event id, the eventId of an occurrence, such as cal_ followed by 24 hex characters.
summarystring: The title, 1 to 255 characters.
startDateTimeOffset or string: When it starts, a DateTimeOffset or ISO 8601 with a zone. A DateTimeOffset is sent as an instant in UTC.
endDateTimeOffset or string: When it ends, after start and at most two years later.
descriptionstring: Notes about the event, up to 8,000 characters.
locationstring: Where it is: a room, an address or a link.
urlstring: A link that belongs to the event.
meetingUrlstring: The link to the video call. An empty string takes it off.
allDaybool: Whether it fills whole days. start and end then mark the days.
timezonestring: The IANA zone the event belongs to, UTC unless you say.
recurrencestring: An RRULE such as FREQ=WEEKLY;BYDAY=MO when it repeats.
attendeeslist: Up to 200 people to invite, each a dictionary with email and, if you like, name and optional. It replaces the whole list.
reminderslist: Up to five reminders, each a dictionary with minutesBefore and, if you like, action (DISPLAY, EMAIL or AUDIO, as in Nextmail\Constants\CalendarReminderActions).
transparencystring: OPAQUE shows you busy and TRANSPARENT free, as in Nextmail\Constants\CalendarTransparencies.
visibilitystring: PUBLIC, PRIVATE or CONFIDENTIAL, as in Nextmail\Constants\CalendarVisibilities.
sendInvitesbool: False keeps the change to your own calendar, and sends nothing.
fromstring: The address the invitations come from. It has to be one the key may send as.
scopestring: occurrence, following or series, as in CalendarEditScopes: which dates of a repeating event change. Left out, the change reaches the event or date the id names.
occurrenceStartDateTimeOffset or string: The start of the date you mean, as ListEventsAsync gives it. Needed with occurrence and following.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A JsonObject for the event as it stands after the change, shaped like the one Calendar.GetEventAsync returns, with sequence one higher.

Example

var entry = await client.Calendar.UpdateEventAsync("cal_3f9a1c7e5b2d48a06c1e9f4b", new Body{    ["start"] = "2026-10-12T10:00:00Z",    ["end"] = "2026-10-12T10:30:00Z",    ["from"] = "[email protected]",}); Console.WriteLine($"{entry["start"]}, sequence {entry["sequence"]}");

Notes

The SDK does not retry it, because a retry after a lost response sends the update to everybody again.
An event organised by somebody else is refused with 403 not_organizer: answer it with RespondToEventAsync instead. An event the key does not reach is a 404.

`Calendar.DeleteEventAsync`

Remove an event from the calendar

calendar:write

Signature

Task<JsonObject> DeleteEventAsync(    string id,    string? scope = null,    DateTimeOffset? occurrenceStart = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Removes an event for good, as Remove does in the app. Nobody else is told, so call off a meeting with others in it with CancelEventAsync instead. For a repeating event, scope occurrence with occurrenceStart removes one date, and following that date and every one after it.

Parameters

idstringRequired: Event id, the eventId of an occurrence, such as cal_ followed by 24 hex characters.
scopestring?: occurrence, following or series: which dates of a repeating event go.
occurrenceStartDateTimeOffset?: The start of the date you mean, as ListEventsAsync gives it. Needed with occurrence and following.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A JsonObject with object, id and deleted set to true.

Example

using Nextmail.Constants; var deleted = await client.Calendar.DeleteEventAsync(    "cal_3f9a1c7e5b2d48a06c1e9f4b",    scope: CalendarEditScopes.Occurrence,    occurrenceStart: new DateTimeOffset(2026, 10, 19, 9, 0, 0, TimeSpan.Zero)); Console.WriteLine($"{deleted["id"]} lost one date");

Notes

An event organised by somebody else is refused with 403 not_organizer, and an event that is gone or that the key does not reach is a 404. An event you may not remove can still be taken off your own calendar with HideEventAsync.

`Calendar.CancelEventAsync`

Call off a meeting

calendar:write

Signature

Task<JsonObject> CancelEventAsync(    string id,    IReadOnlyDictionary<string, object?>? body = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Cancels 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 by email from from, so a meeting with attendees also needs emails:send.

For a repeating meeting, scope occurrence with occurrenceStart calls off one date, and following that date and every one after it. Guests get the matching update.

Parameters

idstringRequired: Event id, the eventId of an occurrence, such as cal_ followed by 24 hex characters.
fromstring: The address the cancellation comes from. It has to be one the key may send as.
scopestring: occurrence, following or series: which dates of a repeating meeting are called off.
occurrenceStartDateTimeOffset or string: The start of the date you mean, as ListEventsAsync gives it. Needed with occurrence and following.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A JsonObject for the event, shaped like the one Calendar.GetEventAsync returns, with status set to CANCELLED.

Example

var entry = await client.Calendar.CancelEventAsync("cal_3f9a1c7e5b2d48a06c1e9f4b", body: new Body { ["from"] = "[email protected]" }); Console.WriteLine($"{entry["summary"]} is now {entry["status"]}");

Notes

The SDK does not retry it, because a retry sends the cancellation again.
An event organised by somebody else is refused with 403 not_organizer.

`Calendar.RespondToEventAsync`

Answer an invitation

calendar:writeemails:send

Signature

Task<JsonObject> RespondToEventAsync(    string id,    IReadOnlyDictionary<string, object?> body,    string? apiKey = null,    CancellationToken cancellationToken = default)

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

Parameters

idstringRequired: Event id, the eventId of an occurrence, such as cal_ followed by 24 hex characters.
responsestringRequired: ACCEPTED, DECLINED or TENTATIVE, as in Nextmail\Constants\CalendarResponses.
respondingAsstring: Which of your invited addresses answers, when there is more than one.
proposedStartDateTimeOffset or string: A new start to propose with your answer, a DateTimeOffset or ISO 8601 with a zone, sent together with proposedEnd. A DateTimeOffset is sent as an instant in UTC.
proposedEndDateTimeOffset or string: The end of the proposed time.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A JsonObject for the event, shaped like the one Calendar.GetEventAsync returns, with your answer on your attendee row.

Example

using Nextmail.Constants; var entry = await client.Calendar.RespondToEventAsync("cal_3f9a1c7e5b2d48a06c1e9f4b", new Body { ["response"] = CalendarResponses.Accepted }); foreach (var attendee in entry["attendees"]?.AsArray() ?? []){    Console.WriteLine($"{attendee?["email"]}: {attendee?["partstat"]}");}

Notes

An event that invited none of the addresses the key may send as is refused with 403 not_invited, and a cancelled meeting with 409 event_cancelled.
When the organiser cannot be reached, nothing changes and the call is a 409 reply_not_sent.
With proposedStart and proposedEnd the organiser gets a counter-proposal, as Propose a new time sends from Google Calendar and Outlook, and decides whether to move the meeting.

`Calendar.DeclineProposalAsync`

Decline a proposed time

calendar:writeemails:send

Signature

Task<JsonObject> DeclineProposalAsync(    string id,    IReadOnlyDictionary<string, object?> body,    string? apiKey = null,    CancellationToken cancellationToken = default)

Keeps the original time of a meeting you organise after a guest proposed another one, as Keep the original does on the event in the app. The guest is told by email from from, or from the organising address, so it needs emails:send as well. To take the proposed time instead, change the event with Calendar.UpdateEventAsync.

Parameters

idstringRequired: Event id, the eventId of an occurrence, such as cal_ followed by 24 hex characters.
attendeestringRequired: The guest whose proposal you decline, by email address.
fromstring: The address the answer is sent from, when it is not the organising address.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A JsonObject for the event, shaped like the one Calendar.GetEventAsync returns, with the guest's proposedStart and proposedEnd cleared.

Example

var entry = await client.Calendar.DeclineProposalAsync("cal_3f9a1c7e5b2d48a06c1e9f4b", new Body { ["attendee"] = "[email protected]" }); Console.WriteLine($"{entry["summary"]} keeps its time");

Notes

A guest who has not proposed a new time is refused with 404 proposal_not_found, and an event somebody else organises with 403 not_organizer.

`Calendar.HideEventAsync`

Hide an event from your calendar

calendar:write

Signature

Task<JsonObject> HideEventAsync(    string id,    string? apiKey = null,    CancellationToken cancellationToken = default)

Takes an event off your own calendar and leaves it for everyone else, as Hide from my calendar does in the app. Use it for an invitation that reached you through a shared address, or an event you may not remove. It hides every date of a repeating event, and stops its reminders for you. UnhideEventAsync brings it back.

Parameters

idstringRequired: Event id, the eventId of an occurrence, such as cal_ followed by 24 hex characters.
apiKeystring?: Overrides the client's API key for this call only.
cancellationTokenCancellationToken: Cancels the request.

Returns

A JsonObject with object, id, uid and hidden set to true.

Example

var hidden = await client.Calendar.HideEventAsync("cal_3f9a1c7e5b2d48a06c1e9f4b"); Console.WriteLine($"{hidden["id"]} hidden: {hidden["hidden"]}");

Notes

Hiding an event that is already hidden changes nothing, so it is safe to repeat. An event the key does not reach is a 404.
It hides the event for the person the key or app acts for, and nobody else. ListEventsAsync leaves it out from then on, and GetEventAsync still finds it, with hidden true.

`Calendar.ImportIcsAsync`

Import a calendar file

calendar:write

Signature

Task<JsonObject> ImportIcsAsync(    Stream data,    string? filename = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Sends an iCalendar (.ics) file as the request body and queues it. Its events become events of your own that you can edit, and nobody on them is sent anything, now or when you change them later, unless you ask for that on the change. Poll GetImportAsync until status is completed.

The file may be 10 MB and hold 25,000 events. Several calendars in one file are merged, and the report keeps their names. An event whose UID is already in the workspace is skipped and counted, never overwritten, so sending the same file twice adds nothing.

data is a readable Stream, and it goes out as text/calendar.

Parameters

dataStreamRequired: The .ics file: a readable Stream.
filenamestring?: The name to show for the file in the list of imports, at most 255 characters.
cancellationTokenCancellationToken: Cancels the request.
apiKeystring?: Overrides the client API key for this call only.

Returns

A JsonObject with status: queued.

Example

await using var file = File.OpenRead("calendar.ics"); var import = await client.Calendar.ImportIcsAsync(file, filename: "calendar.ics"); Console.WriteLine($"{import["id"]} is {import["status"]}");

Notes

A body that is not an iCalendar file is a 400 not_a_calendar_file, an empty one a 400 item_import_empty, and one holding more than 25,000 events a 400 too_many_events.
A file over 10 MB is a 413 item_import_too_large.
To send text you already hold, such as what GetEventIcsAsync returns, encode it first with new TextEncoder().encode(text).
An upload that outlasts the client Timeout fails as a network error, so raise it on the client for a large file on a slow connection.
Not retried automatically.

`Calendar.ListImportsAsync`

List calendar imports

calendar:readPages through results

Signature

Task<Page> ListImportsAsync(    int? limit = null,    string? cursor = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Returns one page of the calendar files and calendars brought in, newest first, each with what it added and what it left out. Beside the files sent with ImportIcsAsync it lists the calendars that came with a mailbox import, and those carry the id of that import in parentImportId.

Paging is keyset. limit: takes 1 to 100 and defaults to 25, and nextCursor goes back as cursor: while hasMore is true. ListAllImportsAsync and IterateImportsAsync do that walk for you.

Parameters

limitint?: Imports per page, a whole number from 1 to 100. The server defaults to 25.
cursorstring?: The nextCursor from the previous page. Never build one yourself.
cancellationTokenCancellationToken: Cancels the request.
apiKeystring?: Overrides the client API key for this call only.

Returns

A Page with items, hasMore and nextCursor.

Example

var page = await client.Calendar.ListImportsAsync(limit: 10); foreach (var import in page){    Console.WriteLine($"{import["id"]} {import["source"]} {import["status"]}: {import["counts"]?["imported"]} events added");}

Notes

source is file for an upload. takeout, caldav and microsoft came with a mailbox import.
A cursor that names no import is a 400 invalid_cursor.
A GET is retried automatically on network failure and on 408, 500, 502, 503 and 504 responses, up to the client MaxRetries, and on a 429 only when it carries a Retry-After of a minute or less.

`Calendar.ListAllImportsAsync`

Collect every calendar import into one list

calendar:readPages through results

Signature

Task<IReadOnlyList<JsonObject>> ListAllImportsAsync(    int? limit = null,    string? cursor = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Follows nextCursor from page to page and returns every calendar import, newest first.

Everything is held in memory before the call returns. Prefer IterateImportsAsync when you can stop early. limit sets the page size of each request, not the total.

Parameters

limitint?: Page size per request, from 1 to 100, defaulting to 25 on the server.
cursorstring?: A cursor from an earlier page to start after.
cancellationTokenCancellationToken: Cancels the request in flight and rejects the whole walk.
apiKeystring?: Overrides the client API key for every page of this walk.

Returns

A list of JsonObject items holding every import across all pages.

Example

var imports = await client.Calendar.ListAllImportsAsync(); Console.WriteLine($"{imports.Count} calendar imports, {imports.Count(import => (bool?)import["undoable"] == true)} of them can be undone");

Notes

A failure on any page rejects the whole call, and the imports already fetched are discarded.

`Calendar.IterateImportsAsync`

Stream calendar imports one at a time

calendar:readPages through results

Signature

IAsyncEnumerable<JsonObject> IterateImportsAsync(    int? limit = null,    string? cursor = null,    string? apiKey = null,    CancellationToken cancellationToken = default)

Returns an IAsyncEnumerable<JsonObject> that yields calendar imports one by one, newest first, and requests the next page only once the current one is drained. Nothing is fetched until you consume it, and breaking out of the loop stops the requests.

Parameters

limitint?: Page size per request, from 1 to 100, defaulting to 25 on the server.
cursorstring?: A cursor from an earlier page to start after.
cancellationTokenCancellationToken: Cancels the request in flight and rejects the whole walk.
apiKeystring?: Overrides the client API key for every page of this walk.

Returns

An IAsyncEnumerable<JsonObject> yielding one import per step.

Example

await foreach (var import in client.Calendar.IterateImportsAsync(limit: 50)){    if ((string?)import["status"] == "failed")    {        Console.WriteLine($"{import["id"]} failed");         break;    }}

Notes

The generator is lazy, so an abandoned loop costs only the pages you consumed.

`Calendar.GetImportAsync`

Get a calendar import

calendar:read

Signature

Task<JsonObject> GetImportAsync(    string id,    string? apiKey = null,    CancellationToken cancellationToken = default)

Returns one calendar import with its counts and its report: the calendars it read, how many events it left out and why, and up to 20 of the events it left out. Poll it after ImportIcsAsync until status is completed or failed.

counts.imported is what was added and counts.skipped what was left out, which report.skipped breaks down by reason: uid-taken for an event that was already here, no-start for one with no start time, invalid for one that could not be read and empty for a file or calendar that held no events.

Parameters

idstringRequired: Calendar import id, iimp_ followed by 24 hex characters.
cancellationTokenCancellationToken: Cancels the request.
apiKeystring?: Overrides the client API key for this call only.

Returns

A JsonObject with status, counts, report, undoable and when it started, finished and was undone.

Example

var import = await client.Calendar.GetImportAsync("iimp_3f9a1c07d2b84e6a9c5b1f20"); Console.WriteLine($"{import["status"]}: {import["counts"]?["imported"]} added, {import["counts"]?["skipped"]} left out");

Notes

An id that names no calendar import is a 404 item_import_not_found.
A GET is retried automatically on network failure and on 408, 500, 502, 503 and 504 responses, up to the client MaxRetries, and on a 429 only when it carries a Retry-After of a minute or less.

Notes

An import that is still running, or was already removed, is a 409 item_import_not_undoable. undoable on the import says whether the call would remove anything.
An id that names no calendar import is a 404 item_import_not_found.
Not retried automatically.
