AWS IAM Identity Center (successor to AWS Single Sign-On) Portal is a web service that makes it easy for you to assign user access to IAM Identity Center resources such as the AWS access portal. Users can get AWS account applications and roles assigned to them and get federated into the application.

Although AWS Single Sign-On was renamed, the sso and identitystore API namespaces will continue to retain their original name for backward compatibility purposes. For more information, see IAM Identity Center rename .

This reference guide describes the IAM Identity Center Portal operations that you can call programatically and includes detailed information on data types and errors.

AWS provides SDKs that consist of libraries and sample code for various programming languages and platforms, such as Java, Ruby, .Net, iOS, or Android. The SDKs provide a convenient way to create programmatic access to IAM Identity Center and other AWS services. For more information about the AWS SDKs, including how to download and install them, see Tools for Amazon Web Services .

Installation

NPM
npm install @aws-sdk/client-sso
Yarn
yarn add @aws-sdk/client-sso
pnpm
pnpm add @aws-sdk/client-sso

SSOClient Operations

Command
Summary
GetRoleCredentialsCommand

Returns the STS short-term credentials for a given role name that is assigned to the user.

ListAccountRolesCommand

Lists all roles that are assigned to the user for a given AWS account.

ListAccountsCommand

Lists all AWS accounts assigned to the user. These AWS accounts are assigned by the administrator of the account. For more information, see Assign User Access  in the IAM Identity Center User Guide. This operation returns a paginated response.

LogoutCommand

Removes the locally stored SSO tokens from the client-side cache and sends an API call to the IAM Identity Center service to invalidate the corresponding server-side IAM Identity Center sign in session.

If a user uses IAM Identity Center to access the AWS CLI, the user’s IAM Identity Center sign in session is used to obtain an IAM session, as specified in the corresponding IAM Identity Center permission set. More specifically, IAM Identity Center assumes an IAM role in the target account on behalf of the user, and the corresponding temporary AWS credentials are returned to the client.

After user logout, any existing IAM role sessions that were created by using IAM Identity Center permission sets continue based on the duration configured in the permission set. For more information, see User authentications  in the IAM Identity Center User Guide.

SSOClient Configuration

Parameter
Type
Description
defaultsMode
Optional
DefaultsMode | Provider<DefaultsMode>
The @smithy/smithy-client#DefaultsMode that will be used to determine how certain default configuration options are resolved in the SDK.
disableHostPrefix
Optional
boolean
Disable dynamically changing the endpoint of the client based on the hostPrefix trait of an operation.
extensions
Optional
RuntimeExtension[]
Optional extensions
logger
Optional
Logger
Optional logger for logging debug/info/warn/error.
maxAttempts
Optional
number | Provider<number>
Value for how many times a request will be made at most in case of retry.
profile
Optional
string
Setting a client profile is similar to setting a value for the AWS_PROFILE environment variable. Setting a profile on a client in code only affects the single client instance, unlike AWS_PROFILE.When set, and only for environments where an AWS configuration file exists, fields configurable by this file will be retrieved from the specified profile within that file. Conflicting code configuration and environment variables will still have higher priority.For client credential resolution that involves checking the AWS configuration file, the client's profile (this value) will be used unless a different profile is set in the credential provider options.
region
Optional
string | Provider<string>
The AWS region to which this client will send requests
requestHandler
Optional
__HttpHandlerUserInput
The HTTP handler to use or its constructor options. Fetch in browser and Https in Nodejs.
retryMode
Optional
string | Provider<string>
Specifies which retry algorithm to use.
useDualstackEndpoint
Optional
boolean | Provider<boolean>
Enables IPv6/IPv4 dualstack endpoint.
useFipsEndpoint
Optional
boolean | Provider<boolean>
Enables FIPS compatible endpoints.
