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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

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

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

Output:
