Calendar API

Aurinko's Calendar API offers a unified REST interface for managing calendars across Google, Outlook, iCloud, etc. Access events, data sync, and simplify scheduling workflows.

Aurinko Calendar API

The Aurinko Calendar API is part of the Aurinko Unified API platform, enabling developers to integrate calendar functionalities effortlessly into their applications. This API abstracts the differences between calendar management services such as Google, Outlook, iCloud Calendar, offering a consistent interface for calendar-related operations.

Functionality

The Aurinko Calendar API provides a REST interface that focuses on accessing and syncing calendars uniformly.

Access data for calendars and events, such as event titles, location, description, dates, ...
Full CRUD (create, read, update, delete) capabilities.
Incremental synchronization

Aurinko account setup

First, create your account in the Aurinko portal, then follow the guide to get your developer API keys.

Calendar API Endpoints

Calendars

Each account connected to Aurinko can have zero or more calendars, and each calendar contains a collection of individual events. Accounts can have many calendars including a primary calendar, secondary calendars, read access calendars, and shared team calendars.

Events

Events are objects within a calendar that generally support all features and attributes of modern scheduling apps like event names, list of participants, descriptions, location, time, etc. Aurinko supports key event functionality, including sending email invites, response status checks and notifications, creating and modifying events, and recurring events.

Synchronization

Calendar sync methods allow developers to implement incremental synchronization of calendar data in a uniform manner across different calendar providers. Aurinko supports requesting updated as well as deleted calendar events, reporting series master and exceptions, auto-expanding a sync range.

Free/busy schedule

Free/busy schedule methods allow developers to check free/busy status for a calendar or available time slots for a meeting.

Booking profiles

Booking profiles methods allow developers to build calendar availability and meeting scheduling apps. List, create, update, and delete booking profiles associated with a user calendar. See meeting time availability according to a booking profile configuration.

Calendar sync quickstart

Start a new sync

A new sync needs to be provisioned by calling the sync-start method /calendars/{calendarId}/sync The sync is available per calendar, hence {calendarId} or primary. timeMin and timeMax specify a time range for the initial full load.

curl -X POST -H 'Authorization: Bearer <account_access_token>' \
    -G https:/api.aurinko.io/v1/calendars/primary/sync[?awaitReady=false] \
        -d timeMin=2019-06-03T10:00:00-07:00 \
        -d timeMax=2020-06-03T10:00:00-07:00

The Aurinko platform will initialize all necessary internal resources and let you know when it's ready to serve data. The response should look like this:

{
    "syncUpdatedToken": "asdfghjklpoiuytrew",
    "syncDeletedToken": "zxcvbnmlkjhgfdsaq",
    "ready": true
}

If the response shows ready: false call the sync-start method again. Once the sync is ready you will get delta tokens syncUpdatedToken, syncDeletedToken and can start loading updated and deleted events.

Initial full sync

Initial requests /calendars/{calendarId}/sync/updated and /calendars/{calendarId}/sync/deleted are equivalent to a full sync in the specified timeMin, timeMax range, plus loading all updated events (deleted events) since the sync start.

curl -X GET -H 'Authorization: Bearer <access_token>' \
    -G https:/api.aurinko.io/v1/calendars/primary/sync/updated \
    -d deltaToken='{syncUpdatedToken}'

Response:

{
    "nextPageToken": "string",
    "nextDeltaToken": "string",
    "records": [{...}]
}

Continue loading pages using provided nextPageToken until you find another nextDeltaToken.

curl -X GET -H 'Authorization: Bearer <access_token>' \
    -G https:/api.aurinko.io/v1/calendars/primary/sync/updated \
    -d pageToken='{nextPageToken}'

Incremental sync

A new deltaToken (nextDeltaToken in response) is provided for loading calendar events that have been modified/deleted since the last sync-updated/sync-deleted request. In cases where a large number of events have changed since the last incremental sync request, you may find a nextPageToken instead of the nextDeltaToken in the response. Continue loading pages using the provided nextPageToken until you find another nextDeltaToken.

Other examples

Calendars

To view a list of all calendars a user has access to, make a request to the /calendars endpoint.

curl -H 'Authorization: Bearer <access_token>' \
    -X GET https:/api.aurinko.io/v1/calendars

You can get information for a single calendar by providing the appropriate calendar id, /calendars/{id}. You can use primary as an ID to get your primary calendar.

curl -H 'Authorization: Bearer <access_token>' \
    -X GET https:/api.aurinko.io/v1/calendars/primary

Calendar events

To get a list of events from a calendar, make a request to the /calendars/{id}/events endpoint.

curl -X POST -H 'Authorization: Bearer <access_token>' \
    -G https:/api.aurinko.io/v1/calendars/primary/events/range \
    -d timeMin=2019-06-03T10:00:00-07:00 \
    -d timeMax=2020-06-03T10:00:00-07:00

To create a new meeting POST json payload to /calendars/{id}/events endpoint:

curl -H 'Authorization: Bearer <access_token>' \
    -X POST https:/api.aurinko.io/v1/calendars/primary/events \
    -d '{
    "subject": "Business lunch",
    "location": "Our favorite cafe",
    "start": {
        "dateTime": "2020-02-04T10:00:00Z",
        "timezone": "America/Los\_Angeles"
    },
    "end": {
        "dateTime": "2020-02-04T11:00:00Z",
        "timezone": "America/Los\_Angeles"
    },
    "meetingInfo": {
        "attendees": [
            {
                "emailAddress": {"address": "[partner@example.com],
                "type": "required"
            }
        ]
    }
}'

Use PATCH request to update existing events and notify meeting attendees of changes:

curl -X POST -H 'Authorization: Bearer <access_token>' \
    https:/api.aurinko.io/v1/calendars/primary/events/{eventId}?notifyAttendees=true \
    -d '{
    "subject": "Business lunch",
    "location": "Another cool place",
    "start": {
        "dateTime": "2020-02-05T10:00:00Z",
        "timezone": "America/Los\_Angeles"
    },
    "end": {
        "dateTime": "2020-02-05T11:00:00Z",
        "timezone": "America/Los\_Angeles"
    },
    "meetingInfo": {
        "attendees": [
            {
                "emailAddress": {"address": "[partner@example.com],
                "type": "required"
            }
        ]
    }
}'
