DescribeParameters - AWS Systems Manager

DescribeParameters

Lists the parameters in your AWS account or the parameters shared with you when you enable the Shared option.

Request results are returned on a best-effort basis. If you specify MaxResults in the request, the response includes information up to the limit specified. The number of items returned, however, can be between zero and the value of MaxResults. If the service reaches an internal limit while processing the results, it stops the operation and returns the matching values up to that point and a NextToken. You can specify the NextToken in a subsequent call to get the next set of results.

Important

If you change the AWS KMS key alias for the KMS key used to encrypt a parameter, then you must also update the key alias the parameter uses to reference KMS. Otherwise, DescribeParameters retrieves whatever the original key alias was referencing.

Request Syntax

{ "Filters": [ { "Key": "string", "Values": [ "string" ] } ], "MaxResults": number, "NextToken": "string", "ParameterFilters": [ { "Key": "string", "Option": "string", "Values": [ "string" ] } ], "Shared": boolean }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Filters

This data type is deprecated. Instead, use ParameterFilters.

Type: Array of ParametersFilter objects

Required: No

MaxResults

The maximum number of items to return for this call. The call also returns a token that you can specify in a subsequent call to get the next set of results.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 50.

Required: No

NextToken

The token for the next set of items to return. (You received this token from a previous call.)

Type: String

Required: No

ParameterFilters

Filters to limit the request results.

Type: Array of ParameterStringFilter objects

Required: No

Shared

Lists parameters that are shared with you.

Note

By default when using this option, the command returns parameters that have been shared using a standard AWS Resource Access Manager Resource Share. In order for a parameter that was shared using the PutResourcePolicy command to be returned, the associated AWS RAM Resource Share Created From Policy must have been promoted to a standard Resource Share using the AWS RAM PromoteResourceShareCreatedFromPolicy API operation.

For more information about sharing parameters, see Working with shared parameters in the AWS Systems Manager User Guide.

Type: Boolean

Required: No
