UpdateUserPoolClient

Updates the specified user pool app client with the specified attributes. You can get a list of the current user pool app client settings using DescribeUserPoolClient.

Important

If you don't provide a value for an attribute, Amazon Cognito sets it to its default value.

You can also use this operation to enable token revocation for user pool clients. For more information about revoking tokens, see RevokeToken.

Note

Amazon Cognito evaluates AWS Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you must use IAM credentials to authorize requests, and you must grant yourself the corresponding IAM permission in a policy.

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.

AccessTokenValidity

The access token time limit. After this limit expires, your user can't use their access token. To specify the time unit for AccessTokenValidity as seconds, minutes, hours, or days, set a TokenValidityUnits value in your API request.

For example, when you set AccessTokenValidity to 10 and TokenValidityUnits to hours, your user can authorize access with their access token for 10 hours.

The default time unit for AccessTokenValidity in an API request is hours. Valid range is displayed below in seconds.

If you don't specify otherwise in the configuration of your app client, your access tokens are valid for one hour.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 86400.

Required: No

AllowedOAuthFlows

The allowed OAuth flows.

code

Use a code grant flow, which provides an authorization code as the response. This code can be exchanged for access tokens with the /oauth2/token endpoint.

implicit

Issue the access token (and, optionally, ID token, based on scopes) directly to your user.

client_credentials

Issue the access token from the /oauth2/token endpoint directly to a non-person user using a combination of the client ID and client secret.

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 3 items.

Valid Values: code | implicit | client_credentials

Required: No

AllowedOAuthFlowsUserPoolClient

Set to true to use OAuth 2.0 features in your user pool app client.

AllowedOAuthFlowsUserPoolClient must be true before you can configure the following features in your app client.

• CallBackURLs: Callback URLs.

• LogoutURLs: Sign-out redirect URLs.

• AllowedOAuthScopes: OAuth 2.0 scopes.

• AllowedOAuthFlows: Support for authorization code, implicit, and client credentials OAuth 2.0 grants.

To use OAuth 2.0 features, configure one of these features in the Amazon Cognito console or set AllowedOAuthFlowsUserPoolClient to true in a CreateUserPoolClient or UpdateUserPoolClient API request. If you don't set a value for AllowedOAuthFlowsUserPoolClient in a request with the AWS CLI or SDKs, it defaults to false.

Type: Boolean

Required: No

AllowedOAuthScopes

The allowed OAuth scopes. Possible values provided by OAuth are phone, email, openid, and profile. Possible values provided by AWS are aws.cognito.signin.user.admin. Custom scopes created in Resource Servers are also supported.

The Amazon Pinpoint analytics configuration necessary to collect metrics for this user pool.

Note

In AWS Regions where Amazon Pinpoint isn't available, user pools only support sending events to Amazon Pinpoint projects in us-east-1. In Regions where Amazon Pinpoint is available, user pools support sending events to Amazon Pinpoint projects within that same Region.

Type: AnalyticsConfigurationType object

Required: No

AuthSessionValidity

Amazon Cognito creates a session token for each API request in an authentication flow. AuthSessionValidity is the duration, in minutes, of that session token. Your user pool native user must respond to each authentication challenge before the session expires.

Type: Integer

Valid Range: Minimum value of 3. Maximum value of 15.

Required: No

CallbackURLs

A list of allowed redirect (callback) URLs for the IdPs.

A redirect URI must:

• Be an absolute URI.

• Be registered with the authorization server.

• Not include a fragment component.

See OAuth 2.0 - Redirection Endpoint.

Amazon Cognito requires HTTPS over HTTP except for http://localhost for testing purposes only.

App callback URLs such as myapp://example are also supported.

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 100 items.

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}]+

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}]+

Required: No

EnablePropagateAdditionalUserContextData

Activates the propagation of additional user context data. For more information about propagation of user context data, see Adding advanced security to a user pool. If you don’t include this parameter, you can't send device fingerprint information, including source IP address, to Amazon Cognito advanced security. You can only activate EnablePropagateAdditionalUserContextData in an app client that has a client secret.

Type: Boolean

Required: No

EnableTokenRevocation

Activates or deactivates token revocation. For more information about revoking tokens, see RevokeToken.

Type: Boolean

Required: No

ExplicitAuthFlows

The authentication flows that you want your user pool client to support. For each app client in your user pool, you can sign in your users with any combination of one or more flows, including with a user name and Secure Remote Password (SRP), a user name and password, or a custom authentication process that you define with Lambda functions.

Note

If you don't specify a value for ExplicitAuthFlows, your user client supports ALLOW_REFRESH_TOKEN_AUTH, ALLOW_USER_SRP_AUTH, and ALLOW_CUSTOM_AUTH.

Valid values include:

• ALLOW_USER_AUTH: Enable selection-based sign-in with USER_AUTH. This setting covers username-password, secure remote password (SRP), passwordless, and passkey authentication. This authentiation flow can do username-password and SRP authentication without other ExplicitAuthFlows permitting them. For example users can complete an SRP challenge through USER_AUTH without the flow USER_SRP_AUTH being active for the app client. This flow doesn't include CUSTOM_AUTH.

• ALLOW_ADMIN_USER_PASSWORD_AUTH: Enable admin based user password authentication flow ADMIN_USER_PASSWORD_AUTH. This setting replaces the ADMIN_NO_SRP_AUTH setting. With this authentication flow, your app passes a user name and password to Amazon Cognito in the request, instead of using the Secure Remote Password (SRP) protocol to securely transmit the password.

• ALLOW_CUSTOM_AUTH: Enable Lambda trigger based authentication.

• ALLOW_USER_PASSWORD_AUTH: Enable user password-based authentication. In this flow, Amazon Cognito receives the password in the request instead of using the SRP protocol to verify passwords.

• ALLOW_USER_SRP_AUTH: Enable SRP-based authentication.

• ALLOW_REFRESH_TOKEN_AUTH: Enable authflow to refresh tokens.

In some environments, you will see the values ADMIN_NO_SRP_AUTH, CUSTOM_AUTH_FLOW_ONLY, or USER_PASSWORD_AUTH. You can't assign these legacy ExplicitAuthFlows values to user pool clients at the same time as values that begin with ALLOW_, like ALLOW_USER_SRP_AUTH.

Type: Array of strings

Valid Values: ADMIN_NO_SRP_AUTH | CUSTOM_AUTH_FLOW_ONLY | USER_PASSWORD_AUTH | ALLOW_ADMIN_USER_PASSWORD_AUTH | ALLOW_CUSTOM_AUTH | ALLOW_USER_PASSWORD_AUTH | ALLOW_USER_SRP_AUTH | ALLOW_REFRESH_TOKEN_AUTH | ALLOW_USER_AUTH

Required: No

IdTokenValidity

The ID token time limit. After this limit expires, your user can't use their ID token. To specify the time unit for IdTokenValidity as seconds, minutes, hours, or days, set a TokenValidityUnits value in your API request.

For example, when you set IdTokenValidity as 10 and TokenValidityUnits as hours, your user can authenticate their session with their ID token for 10 hours.

The default time unit for IdTokenValidity in an API request is hours. Valid range is displayed below in seconds.

If you don't specify otherwise in the configuration of your app client, your ID tokens are valid for one hour.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 86400.

Required: No

LogoutURLs

A list of allowed logout URLs for the IdPs.

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 100 items.

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}]+

Required: No

PreventUserExistenceErrors

Errors and responses that you want Amazon Cognito APIs to return during authentication, account confirmation, and password recovery when the user doesn't exist in the user pool. When set to ENABLED and the user doesn't exist, authentication returns an error indicating either the username or password was incorrect. Account confirmation and password recovery return a response indicating a code was sent to a simulated destination. When set to LEGACY, those APIs return a UserNotFoundException exception if the user doesn't exist in the user pool.

Valid values include:

• ENABLED - This prevents user existence-related errors.

• LEGACY - This represents the early behavior of Amazon Cognito where user existence related errors aren't prevented.

Defaults to LEGACY when you don't provide a value.

This setting affects the behavior of the following APIs:

• AdminInitiateAuth

• AdminRespondToAuthChallenge

• InitiateAuth

• RespondToAuthChallenge

• ForgotPassword

• ConfirmForgotPassword

• ConfirmSignUp

• ResendConfirmationCode

Type: String

Valid Values: LEGACY | ENABLED

Required: No

ReadAttributes

The list of user attributes that you want your app client to have read access to. After your user authenticates in your app, their access token authorizes them to read their own attribute value for any attribute in this list. An example of this kind of activity is when your user selects a link to view their profile information. Your app makes a GetUser API request to retrieve and display your user's profile data.

When you don't specify the ReadAttributes for your app client, your app can read the values of email_verified, phone_number_verified, and the Standard attributes of your user pool. When your user pool app client has read access to these default attributes, ReadAttributes doesn't return any information. Amazon Cognito only populates ReadAttributes in the API response if you have specified your own custom set of read attributes.

Type: Array of strings

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

Required: No

RefreshTokenValidity

The refresh token time limit. After this limit expires, your user can't use their refresh token. To specify the time unit for RefreshTokenValidity as seconds, minutes, hours, or days, set a TokenValidityUnits value in your API request.

For example, when you set RefreshTokenValidity as 10 and TokenValidityUnits as days, your user can refresh their session and retrieve new access and ID tokens for 10 days.

The default time unit for RefreshTokenValidity in an API request is days. You can't set RefreshTokenValidity to 0. If you do, Amazon Cognito overrides the value with the default value of 30 days. Valid range is displayed below in seconds.

If you don't specify otherwise in the configuration of your app client, your refresh tokens are valid for 30 days.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 315360000.

Required: No

SupportedIdentityProviders

A list of provider names for the identity providers (IdPs) that are supported on this client. The following are supported: COGNITO, Facebook, Google, SignInWithApple, and LoginWithAmazon. You can also specify the names that you configured for the SAML and OIDC IdPs in your user pool, for example MySAMLIdP or MyOIDCIdP.

This setting applies to providers that you can access with the hosted UI and OAuth 2.0 authorization server. The removal of COGNITO from this list doesn't prevent authentication operations for local users with the user pools API in an AWS SDK. The only way to prevent API-based authentication is to block access with a AWS WAF rule.

Type: Array of strings

Length Constraints: Minimum length of 1. Maximum length of 32.

Pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}\p{Z}]+

Required: No

TokenValidityUnits

The time units you use when you set the duration of ID, access, and refresh tokens. The default unit for RefreshToken is days, and the default for ID and access tokens is hours.

Type: TokenValidityUnitsType object

Required: No

UserPoolId

The user pool ID for the user pool where you want to update the user pool client.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 55.

Pattern: [\w-]+_[0-9a-zA-Z]+

Required: Yes

WriteAttributes

The list of user attributes that you want your app client to have write access to. After your user authenticates in your app, their access token authorizes them to set or modify their own attribute value for any attribute in this list. An example of this kind of activity is when you present your user with a form to update their profile information and they change their last name. Your app then makes an UpdateUserAttributes API request and sets family_name to the new value.

When you don't specify the WriteAttributes for your app client, your app can write the values of the Standard attributes of your user pool. When your user pool has write access to these default attributes, WriteAttributes doesn't return any information. Amazon Cognito only populates WriteAttributes in the API response if you have specified your own custom set of write attributes.

If your app client allows users to sign in through an IdP, this array must include all attributes that you have mapped to IdP attributes. Amazon Cognito updates mapped attributes when users sign in to your application through an IdP. If your app client does not have write access to a mapped attribute, Amazon Cognito throws an error when it tries to update the attribute. For more information, see Specifying IdP Attribute Mappings for Your user pool.

Type: Array of strings

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

Required: No
