[ 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.

--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.
