API Reference (API Version 2010-05-08)

ListEntitiesForPolicy

Lists all IAM users, groups, and roles that the specified managed policy is attached to.

You can use the optional EntityFilter parameter to limit the results to a particular type of entity (users, groups, or roles). For example, to list only the roles that are attached to the specified policy, set EntityFilter to Role.

You can paginate the results using the MaxItems and Marker parameters.

Request Parameters

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

EntityFilter

The entity type to use for filtering the results.

For example, when EntityFilter is Role, only the roles that are attached to the specified policy are returned. This parameter is optional. If it is not included, all attached entities (users, groups, and roles) are returned. The argument for this parameter must be one of the valid values listed below.

Type: String

Valid Values: User | Role | Group | LocalManagedPolicy | AWSManagedPolicy

Required: No

Marker

Use this parameter only when paginating results and only after you receive a response indicating that the results are truncated. Set it to the value of the Marker element in the response that you received to indicate where the next call should start.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 320.

Pattern: [\u0020-\u00FF]+

Required: No

MaxItems

(Optional) Use this only when paginating results to indicate the maximum number of items you want in the response. If additional items exist beyond the maximum you specify, the IsTruncated response element is true.

If you do not include this parameter, it defaults to 100. Note that IAM might return fewer results, even when there are more results available. In that case, the IsTruncated response element returns true and Marker contains a value to include in the subsequent call that tells the service where to continue from.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 1000.

Required: No

PathPrefix

The path prefix for filtering the results. This parameter is optional. If it is not included, it defaults to a slash (/), listing all entities.

This paramater allows (per its regex pattern) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes, containing any ASCII character from the ! (\u0021) thru the DEL character (\u007F), including most punctuation characters, digits, and upper and lowercased letters.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: (\u002F)|(\u002F[\u0021-\u007F]+\u002F)

Required: No

PolicyArn

The Amazon Resource Name (ARN) of the IAM policy for which you want the versions.

For more information about ARNs, see Amazon Resource Names (ARNs) and AWS Service Namespaces in the AWS General Reference.

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Required: Yes

Response Elements

The following elements are returned by the service.

IsTruncated

A flag that indicates whether there are more items to return. If your results were truncated, you can make a subsequent pagination request using the Marker request parameter to retrieve more items. Note that IAM might return fewer than the MaxItems number of results even when there are more results available. We recommend that you check IsTruncated after every call to ensure that you receive all of your results.

Type: Boolean

Marker

When IsTruncated is true, this element is present and contains the value to use for the Marker parameter in a subsequent pagination request.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 320.

Pattern: [\u0020-\u00FF]+

PolicyGroups.member.N

A list of IAM groups that the policy is attached to.

Type: Array of PolicyGroup objects

PolicyRoles.member.N

A list of IAM roles that the policy is attached to.

Type: Array of PolicyRole objects

PolicyUsers.member.N

A list of IAM users that the policy is attached to.

Type: Array of PolicyUser objects

Errors

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

InvalidInput

The request was rejected because an invalid or out-of-range value was supplied for an input parameter.

HTTP Status Code: 400

NoSuchEntity

The request was rejected because it referenced an entity that does not exist. The error message describes the entity.

HTTP Status Code: 404

ServiceFailure

The request processing has failed because of an unknown error, exception or failure.

HTTP Status Code: 500
