Change Events for Tasks and Events
You can receive change events for single and recurring tasks and calendar events,
including events with invitees.
-
Recurring Activities
The activity series record is tracked in a single change event. Each occurrence in the series is tracked by an individual change event. -
Event Invitees
Change events are generated for event invitees in addition to the calendar event record. When a Salesforce user is invited to a calendar event, a child calendar event record is created for the invitee. A child calendar event is an Event record with the IsChild field set to true and OwnerId set to the invitee’s user ID. -
Updating Recurring Calendar Events
If a critical change is made to a recurring calendar event, such as changing the recurrence pattern or the recurrence start date, the series is deleted and recreated. -
Shared Activities and Parent Records for Tasks and Events
If Shared Activities is enabled, the relationships between a task and its parent records (for example, contacts and lead), which correspond to TaskRelation objects, are tracked through change events.
