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.

Event Notification Rules

Notifications are generated for record events based on how you configure your PushTopic. The Streaming API matching logic uses the NotifyForOperationCreate, NotifyForOperationUpdate, NotifyForOperationDelete, NotifyForOperationUndelete, and NotifyForFields fields in a PushTopic record to determine whether to generate a notification.

Clients must connect using the cometd/29.0 (or later) Streaming API endpoint to receive delete and undelete event notifications.
