Clio Calendars API is one of 85 APIs that [Clio](https://apis.io/providers/clio/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Calendars. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and authentication docs.

Calendars contain Calendar Entries. All Clio accounts contain one firm Calendar ("AccountCalendar"), personal Calendars for each user ("UserCalendar"), and any number of manually created Calendars ("AdhocCalendar"). [Calendar sharing](https://help.clio.com/hc/en-us/articles/9289973325467-Calendar-Sharing-and-Permissions) settings determine if a Calendar is visible to a User, and if that User is able to create or edit Calendar Entries on that Calendar.
