# About the Events Views API

The Events Views API offers you webhooks that let you easily keep track of the
next year in a schedule. Subscribing to the view gives you details about changes
to all single-occurrence, `EXCEPTION`, and `INSTANCE`
[events](https://dev.wix.com/docs/rest/business-management/calendar/events-v3/introduction.md)
at least one year into the future. Periodically, the view is extended.

With the Events Views API, you can:

+ Track in real-time when a single-occurrence, `EXCEPTION`, or `INSTANCE`
  event is created or updated.
+ Retrieve the view's current end date and get notified when it's extended.

For more in-depth scheduling management, see:

+ [Events API](https://dev.wix.com/docs/rest/business-management/calendar/events-v3/introduction.md)
+ [Schedules API](https://dev.wix.com/docs/rest/business-management/calendar/schedules-v3/introduction.md)

## Before you begin

It’s important to note the following points before starting to code:

+ An event view is complete for at least a full year into the future at all
  times. Don't rely on completeness further than 1 year into the future.
+ You can't update the end date of the view.
+ `MASTER` events aren't included in the webhooks of the Events View API.

## Use cases

+ [Sync calendars to an external system](https://dev.wix.com/docs/rest/business-management/calendar/sample-flows.md#sync-calendars-to-an-external-system).

## Terminology

+ **Event view**: Subscribing to the event view lets you keep track of changes
  to a calendar's single-occurrence, `EXCEPTION`, and `INSTANCE` events at least
  one year into the future.
