- Source: [`aws-ssm/lib/parameter.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0/packages/aws-cdk-lib/aws-ssm/lib/parameter.ts#L441)
- Type last changed: v2.42.0 · 16 Sep 2022

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_ssm as ssm } from 'aws-cdk-lib';
const listParameterAttributes: ssm.ListParameterAttributes = {
  parameterName: 'parameterName',

  // the properties below are optional
  elementType: ssm.ParameterValueType.STRING,
  simpleName: false,
  version: 123,
};
```

## Properties

- `elementType`: [ParameterValueType](/cdk/api/v2/docs/aws-cdk-lib.aws_ssm.ParameterValueType.html) = ParameterValueType.STRING — The type of the string list parameter value.

  Using specific types can be helpful in catching invalid values
  at the start of creating or updating a stack. CloudFormation validates
  the values against existing values in the account.

  Note - if you want to allow values from different AWS accounts, use
  ParameterValueType.STRING

- `parameterName`: string (required) — The name of the parameter store value.

  This value can be a token or a concrete string. If it is a concrete string
  and includes "/" it must also be prefixed with a "/" (fully-qualified).

- `simpleName`: boolean — Indicates whether the parameter name is a simple name.

  **Default:** auto-detect based on `parameterName`

  A parameter name
  without any "/" is considered a simple name. If the parameter name includes
  "/", setting simpleName to true might cause unintended issues such
  as duplicate "/" in the resulting ARN.

  This is required only if `parameterName` is a token, which means we
  are unable to detect if the name is simple or "path-like" for the purpose
  of rendering SSM parameter ARNs.

  If `parameterName` is not specified, `simpleName` must be `true` (or
  undefined) since the name generated by AWS CloudFormation is always a
  simple name.

- `version`: number — The version number of the value you wish to retrieve.

  **Default:** The latest version will be retrieved.
