Cally API

The Cally API lets API Clients create Callys, read public and private Cally data, update titles, replace Cally event collections, and create, update, or delete individual Events.

Use it when you want to automate Cally creation, keep Event data in sync from another system, or build a custom workflow around public Cally and Subscription URLs.
