[ aws . sns ]



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

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--topic-arn <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--topic-arn (string)

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

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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.


The following command gets the attributes of a topic named my-topic:

        "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}}",
