GetBucketNotificationConfiguration

Returns the notification configuration of a bucket.

If notifications are not enabled on the bucket, the action returns an empty NotificationConfiguration element.

By default, you must be the bucket owner to read the notification configuration of a bucket. However, the bucket owner can use a bucket policy to grant permission to other users to read this configuration with the s3:GetBucketNotification permission.

To use this API against an access point, provide the alias of the access point in place of the bucket name.

For more information about setting and reading the notification configuration on a bucket, see Setting Up Notification of Bucket Events. For more information about bucket policies, see Using Bucket Policies.
