Parameter
Description
token
Required

Account token. The account token is available in the Account section and is incorporated in all code examples on this page.
calendar_id
Required

Id of the calendar to create the event in.
title
Required

Title of the event. Single line string.
description
Description of the event. Use \n to separate lines. The field accepts plain text.
location
Location of the event, e.g. "1600 Amphitheatre Pkwy, Mountain View, CA 94043".
organizer
Event organizer, e.g. "Thomas Scott".

If you fill out organizer you must also include the organizer_email field.

If you include an organizer and an organizer_email, the event is considered to be a "meeting" by calendar clients like Outlook. If you don't include the fields, the event is considered to be an "appointment".
organizer_email
Event organizer e-mail, e.g. "thomas@example.com".

If you fill out organizer_email you must also include the organizer field.

If you include an organizer and an organizer_email, the event is considered to be a "meeting" by calendar clients like Outlook. If you don't include the fields, the event is considered to be an "appointment".
start_date
Required

Start date of the event. Accepts most date/time formats, e.g. 01/16/2021 03:00 PM (12-hour format) or 16-01-2021 15:00 (24-hour format).

Use numeric values to describe the date, e.g. "01/30/2021" and not textual, e.g. "January 30th, 2021".

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed. If, however, the year is given in a two digit format and the separator is a dash (-, the date string is parsed as y-m-d. To avoid potential ambiguity, it's best to use ISO 8601 (YYYY-MM-DD) dates

Date examples:
01/16/2021 03:00 PM or 16-01-2021 15:00 or 2021/01/16 03:00 PM or 2021-01-16 15:00
end_date
End date of the event. Accepts most date/time formats, e.g. 01/16/2021 05:00 PM (12-hour format) or 16-01-2021 17:00 (24-hour format).

Use numeric values to describe the date, e.g. "01/30/2021" and not textual, e.g. "January 30th, 2021".

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

Date examples:
01/16/2021 05:00 PM or 16-01-2021 17:00 or 2021/01/16 05:00 PM or 2021-01-16 17:00

The timezone parameter converts the date/time to Zulu time / GMT / UTC. The timezone parameter defaults to "" if a timezone is not defined.

You can find a list of all time zones (Section: List of time zones) at the bottom of this page.

Explanation: The timezone parameter makes sure the date/time is correct no matter if you are in New York or Sydney.

event_id
Required

Id of the event to save.
title
Required

Title of the event. Single line string.
description
Description of the event. Use \n to separate lines. The field accepts plain text.
location
Location of the event, e.g. "1600 Amphitheatre Pkwy, Mountain View, CA 94043".
organizer
Event organizer, e.g. "Thomas Scott".

If you fill out organizer you must also include the organizer_email field.

If you include an organizer and an organizer_email, the event is considered to be a "meeting" by calendar clients like Outlook. If you don't include the fields, the event is considered to be an "appointment".

If you fill out organizer_email you must also include the organizer field.

start_date
Required

Start date of the event. Accepts most date/time formats, e.g. 01/16/2021 03:00 PM (12-hour format) or 16-01-2021 15:00 (24-hour format).

Use numeric values to describe the date, e.g. "01/30/2021" and not textual, e.g. "January 30th, 2021".

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed. If, however, the year is given in a two digit format and the separator is a dash (-, the date string is parsed as y-m-d. To avoid potential ambiguity, it's best to use ISO 8601 (YYYY-MM-DD) dates

Date examples:
01/16/2021 03:00 PM or 16-01-2021 15:00 or 2021/01/16 03:00 PM or 2021-01-16 15:00
