Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

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.

Similarly, the relationships between a calendar event and its parent records, which correspond to EventRelation objects, are tracked. You can receive change events for task relationships on the /data/TaskRelationChangeEvent channel, and for event relationships on the /data/EventRelationChangeEvent channel.

When Shared Activities is not enabled, EventRelation objects associate a calendar event with invitees only.
