ListRoles - Amazon Identity and Access Management
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

ListRoles

Lists the IAM roles that have the specified path prefix. If there are none, the operation returns an empty list. For more information about roles, see IAM roles in the IAM User Guide.

Note

IAM resource-listing operations return a subset of the available attributes for the resource. This operation does not return the following attributes, even though they are an attribute of the returned object:

  • PermissionsBoundary

  • RoleLastUsed

  • Tags

To view all of the information for a role, see GetRole.

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.

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.

Pattern: [\u0020-\u00FF]+

Required: No

MaxItems

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, the number of items 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. For example, the prefix /application_abc/component_xyz/ gets all roles whose path starts with /application_abc/component_xyz/.

This parameter is optional. If it is not included, it defaults to a slash (/), listing all roles. This parameter allows (through 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. In addition, it can contain any ASCII character from the ! (\u0021) through 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[\u0021-\u007F]*

Required: No

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 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

Roles.member.N

A list of roles.

Type: Array of Role objects

Errors

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

ServiceFailure

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

HTTP Status Code: 500
