Properties common to all events

When an event is triggered, the Event Grid service sends data about that event to subscribing endpoint. This section contains an example of what that data would look like for each event. Each event has the following top-level data:

Property Type Description
topic string Full resource path to the event source. This field isn't writeable. Event Grid provides this value.
subject string Publisher-defined path to the event subject.
eventType string One of the registered event types for this event source.
eventTime string The time the event is generated based on the provider's UTC time.
id string Unique identifier for the event.
data object Blob storage event data.
dataVersion string The schema version of the data object. The publisher defines the schema version.
metadataVersion string The schema version of the event metadata. Event Grid defines the schema of the top-level properties. Event Grid provides this value.
