See ‘aws help’ for descriptions of global parameters.


--names <value>
[--with-decryption | --no-with-decryption]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--names (list)

Names of the parameters for which you want to query information.



"string" "string" ...

--with-decryption | --no-with-decryption (boolean)

Return decrypted secure string value. Return decrypted values for secure string parameters. This flag is ignored for String and StringList parameter types.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


Example 1: To list the values for a parameter

The following get-parameters example lists the values for the three specified parameters.

aws ssm get-parameters \
    --names "MyStringParameter" "MyStringListParameter" "MyInvalidParameterName"


    "Parameters": [
            "Name": "MyStringListParameter",
            "Type": "StringList",
            "Value": "alpha,beta,gamma",
            "Version": 1,
            "LastModifiedDate": 1582154764.222,
            "ARN": "arn:aws:ssm:us-east-2:111222333444:parameter/MyStringListParameter"
            "Name": "MyStringParameter",
            "Type": "String",
            "Value": "Vici",
            "Version": 3,
            "LastModifiedDate": 1582156117.545,
            "ARN": "arn:aws:ssm:us-east-2:111222333444:parameter/MyStringParameter"
    "InvalidParameters": [

Example 2: To list names and values of multiple parameters using the ``–query`` option

The following get-parameters example lists the names and values for the specified parameters.

aws ssm get-parameters \
    --names MyStringParameter MyStringListParameter \
    --query "Parameters[*].{Name:Name,Value:Value}"


        "Name": "MyStringListParameter",
        "Value": "alpha,beta,gamma"
        "Name": "MyStringParameter",
        "Value": "Vidi"
