get-topic-attributes¶

Description¶

Returns all of the properties of a topic. Topic properties returned might differ based on the authorization of the user.

Synopsis¶

  get-topic-attributes
--topic-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--topic-arn (string)

The ARN of the topic whose properties you want to get.

--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 .

To retrieve the attributes of a topic

The following get-topic-attributes example displays the attributes for the specified topic.

aws sns get-topic-attributes \
    --topic-arn "arn:aws:sns:us-west-2:123456789012:my-topic"

Output:

{
    "Attributes": {
        "SubscriptionsConfirmed": "1",
        "DisplayName": "my-topic",
        "SubscriptionsDeleted": "0",
        "EffectiveDeliveryPolicy": "{\"http\":{\"defaultHealthyRetryPolicy\":{\"minDelayTarget\":20,\"maxDelayTarget\":20,\"numRetries\":3,\"numMaxDelayRetries\":0,\"numNoDelayRetries\":0,\"numMinDelayRetries\":0,\"backoffFunction\":\"linear\"},\"disableSubscriptionOverrides\":false}}",
        "Owner": "123456789012",
        "Policy": "{\"Version\":\"2008-10-17\",\"Id\":\"__default_policy_ID\",\"Statement\":[{\"Sid\":\"__default_statement_ID\",\"Effect\":\"Allow\",\"Principal\":{\"AWS\":\"*\"},\"Action\":[\"SNS:Subscribe\",\"SNS:ListSubscriptionsByTopic\",\"SNS:DeleteTopic\",\"SNS:GetTopicAttributes\",\"SNS:Publish\",\"SNS:RemovePermission\",\"SNS:AddPermission\",\"SNS:SetTopicAttributes\"],\"Resource\":\"arn:aws:sns:us-west-2:123456789012:my-topic\",\"Condition\":{\"StringEquals\":{\"AWS:SourceOwner\":\"0123456789012\"}}}]}",
        "TopicArn": "arn:aws:sns:us-west-2:123456789012:my-topic",
        "SubscriptionsPending": "0"
    }
}

Output¶

Attributes -> (map)

A map of the topic’s attributes. Attributes in this map include the following:

DeliveryPolicy – The JSON serialization of the topic’s delivery policy.

DisplayName – The human-readable name used in the From field for notifications to email and email-json endpoints.

Owner – The Amazon Web Services account ID of the topic’s owner.

Policy – The JSON serialization of the topic’s access control policy.

SubscriptionsConfirmed – The number of confirmed subscriptions for the topic.

SubscriptionsDeleted – The number of deleted subscriptions for the topic.

SubscriptionsPending – The number of subscriptions pending confirmation for the topic.

TopicArn – The topic’s ARN.

EffectiveDeliveryPolicy – The JSON serialization of the effective delivery policy, taking system defaults into account.

The following attribute applies only to server-side-encryption :

KmsMasterKeyId - The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms . For more examples, see KeyId in the Key Management Service API Reference .

The following attributes apply only to FIFO topics :

FifoTopic – When this is set to true , a FIFO topic is created.

ContentBasedDeduplication – Enables content-based deduplication for FIFO topics.

By default, ContentBasedDeduplication is set to false . If you create a FIFO topic and this attribute is false , you must specify a value for the MessageDeduplicationId parameter for the Publish action.

When you set ContentBasedDeduplication to true , Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message). (Optional) To override the generated value, you can specify a value for the MessageDeduplicationId parameter for the Publish action.
