Description
The API Events addon exposes EventON data through the REST API, allowing external applications to query, create, and update calendar events through authenticated endpoints. Designed for developers and teams that need to integrate the site schedule with mobile apps, internal systems, or third-party services, the component opens up EventON content beyond the standard WordPress interface.

Who Is It For?
