GetParametersByPath - AWS Systems Manager


Retrieve information about one or more parameters in a specific hierarchy.

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.

Request Syntax

{ "MaxResults": number, "NextToken": "string", "ParameterFilters": [ { "Key": "string", "Option": "string", "Values": [ "string" ] } ], "Path": "string", "Recursive": boolean, "WithDecryption": 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.


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 10.

Required: No


A token to start the list. Use this token to get the next set of results.

Type: String

Required: No


Filters to limit the request results.


The following Key values are supported for GetParametersByPath: Type, KeyId, and Label.

The following Key values aren't supported for GetParametersByPath: tag, DataType, Name, Path, and Tier.

Type: Array of ParameterStringFilter objects

Required: No


The hierarchy for the parameter. Hierarchies start with a forward slash (/). The hierarchy is the parameter name except the last part of the parameter. For the API call to succeed, the last part of the parameter name can't be in the path. A parameter name hierarchy can have a maximum of 15 levels. Here is an example of a hierarchy: /Finance/Prod/IAD/WinServ2016/license33

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: Yes


Retrieve all parameters within a hierarchy.


If a user has access to a path, then the user can access all levels of that path. For example, if a user has permission to access path /a, then the user can also access /a/b. Even if a user has explicitly been denied access in IAM for parameter /a/b, they can still call the GetParametersByPath API operation recursively for /a and view /a/b.

Type: Boolean

Required: No


Retrieve all parameters in a hierarchy with their value decrypted.

Type: Boolean

Required: No

Response Syntax

{ "NextToken": "string", "Parameters": [ { "ARN": "string", "DataType": "string", "LastModifiedDate": number, "Name": "string", "Selector": "string", "SourceResult": "string", "Type": "string", "Value": "string", "Version": number } ] }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.


The token for the next set of items to return. Use this token to get the next set of results.

Type: String


A list of parameters found in the specified hierarchy.

Type: Array of Parameter objects


For information about the errors that are common to all actions, see Common Errors.

HTTP Status Code: 400


The specified filter option isn't valid. Valid options are Equals and BeginsWith. For Path filter, valid options are Recursive and OneLevel.

HTTP Status Code: 400


The filter value isn't valid. Verify the value and try again.

HTTP Status Code: 400


The query key ID isn't valid.

HTTP Status Code: 400


The specified token isn't valid.

HTTP Status Code: 400
