get-bucket-notification-configuration¶

Description¶

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.

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 .

The following action is related to GetBucketNotification :

PutBucketNotification

Synopsis¶

  get-bucket-notification-configuration
--bucket <value>
[--expected-bucket-owner <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--bucket (string)

The name of the bucket for which to get the notification configuration.

--expected-bucket-owner (string)

The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

The following command retrieves the notification configuration for a bucket named my-bucket:

aws s3api get-bucket-notification-configuration --bucket my-bucket

Output:
