Per the [AWS standard](https://docs.aws.amazon.com/AmazonS3/latest/userguide/notification-how-to-filtering.html), two definitions cannot potentially publish events for the same S3 operation. For example, you cannot have a definition that publishes an event on creation of an object with the `abcdef` object key prefix and a definition for creation of objects prefixed with `abc`. ## Configuring S3 Bucket Notifications in VAST Web UI To configure event publishing for a view, use the Bucket Notifications tab in view settings (Element Store -> Views -> choose to create or edit a view). > [!NOTE] > Note > > Event publishing settings are only available if the view has the *S3 Bucket* protocol enabled and is controlled with the *S3 Native* security flavor. You can specify the following: - One or more types of events for which you want to send notifications. - The event broker (which can be [VAST Event Broker](/docs-5-4/docs/en/configuring-vast-event-broker-tg) or a [third-party event broker](/docs-5-4/docs/en/managing-third-party-event-brokers-tg)) and the [topic](/docs-5-4/docs/en/managing-event-topics-tg) to which to publish events. - (Optionally) Object key prefix and/or suffix to have the events filtered based on S3 object keys. > [!NOTE] > Note > > For a complete procedure, see [Creating Views](/docs-5-4/docs/en/creating-views-tg).Creating Views
