get_bucket_notification_configuration

S3.Client.get_bucket_notification_configuration(**kwargs)

Note

This operation is not supported for directory buckets.

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.

When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.

When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes.

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.

)

Parameters:

• Bucket (string) –

  [REQUIRED]

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

  When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.

For more information about InvalidAccessPointAliasError, see List of Error Codes.

• ExpectedBucketOwner (string) – The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

  • TopicConfigurations (list) –

    The topic to which notifications are sent and the events for which notifications are generated.

    • (dict) –

      A container for specifying the configuration for publication of messages to an Amazon Simple Notification Service (Amazon SNS) topic when Amazon S3 detects specified events.

      • Id (string) –

        An optional unique identifier for configurations in a notification configuration. If you don’t provide one, Amazon S3 will assign an ID.

      • TopicArn (string) –

        The Amazon Resource Name (ARN) of the Amazon SNS topic to which Amazon S3 publishes a message when it detects events of the specified type.

      • Events (list) –

        The Amazon S3 bucket event about which to send notifications. For more information, see Supported Event Types in the Amazon S3 User Guide.

        • (string) –

          The bucket event for which to send notifications.

      • Filter (dict) –

        Specifies object key name filtering rules. For information about key name filtering, see Configuring event notifications using object key name filtering in the Amazon S3 User Guide.

        • Key (dict) –

          A container for object key name prefix and suffix filtering rules.

          • FilterRules (list) –

A prefix is a specific string of characters at the beginning of an object key name, which you can use to organize objects. For example, you can start the key names of related objects with a prefix, such as 2023- or engineering/. Then, you can use FilterRule to find objects in a bucket with key names that have the same prefix. A suffix is similar to a prefix, but it is at the end of the object key name instead of at the beginning.

                The object key name prefix or suffix identifying one or more objects to which the filtering rule applies. The maximum length is 1,024 characters.
