RefreshTokenValidity

integer

optional

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.

>= 0<= 315360000

AccessTokenValidity

integer

optional

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.

>= 1<= 86400

IdTokenValidity

integer

optional

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 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 ID tokens are valid for one hour.

>= 1<= 86400

TokenValidityUnits

object

optional

The time units used to specify the token validity times of each token type: ID, access, and refresh.

ReadAttributes

array[string]

optional

The Read-only attributes.

WriteAttributes

array[string]

optional

The writeable attributes.

ExplicitAuthFlows

array[string]

optional

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.

Valid values include:

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.

Allowed values:

ADMIN_NO_SRP_AUTHCUSTOM_AUTH_FLOW_ONLYUSER_PASSWORD_AUTHALLOW_ADMIN_USER_PASSWORD_AUTHALLOW_CUSTOM_AUTHALLOW_USER_PASSWORD_AUTHALLOW_USER_SRP_AUTHALLOW_REFRESH_TOKEN_AUTH

SupportedIdentityProviders

array[string]

optional

A list of provider names for the IdPs that this client supports. The following are supported: COGNITO, Facebook, Google, SignInWithApple, LoginWithAmazon, and the names of your own SAML and OIDC providers.

CallbackURLs

array[string]

optional

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.

>= 0 items<= 100 items

LogoutURLs

array[string]

optional

A list of allowed logout URLs for the IdPs.

>= 0 items<= 100 items

DefaultRedirectURI

string

optional

The default redirect URI. Must be in the CallbackURLs list.

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.

>= 1 characters<= 1024 characters

Match pattern:

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

AllowedOAuthFlows

array[string]

optional

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.

>= 0 items<= 3 items

Allowed values:

codeimplicitclient_credentials

AllowedOAuthScopes

array[string]

optional

The OAuth scopes that your app client supports. Possible values that OAuth provides are phone, email, openid, and profile. Possible values that Amazon Web Services provides are aws.cognito.signin.user.admin. Amazon Cognito also supports custom scopes that you create in Resource Servers.

<= 50 items

AllowedOAuthFlowsUserPoolClient

boolean

optional

Set to true if the client is allowed to follow the OAuth protocol when interacting with Amazon Cognito user pools.

AnalyticsConfiguration

object

optional

The Amazon Pinpoint analytics configuration for the user pool client.

PreventUserExistenceErrors

enum<string>

optional

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 old behavior of Amazon Cognito where user existence related errors aren't prevented.

Allowed values:

LEGACYENABLED

EnableTokenRevocation

boolean

optional

Indicates whether token revocation is activated for the user pool client. When you create a new user pool client, token revocation is activated by default. For more information about revoking tokens, see RevokeToken.

EnablePropagateAdditionalUserContextData

boolean

optional

When EnablePropagateAdditionalUserContextData is true, Amazon Cognito accepts an IpAddress value that you send in the UserContextData parameter. The UserContextData parameter sends information to Amazon Cognito advanced security for risk analysis. You can send UserContextData when you sign in Amazon Cognito native users with the InitiateAuth and RespondToAuthChallenge API operations.

When EnablePropagateAdditionalUserContextData is false, you can't send your user's source IP address to Amazon Cognito advanced security with unauthenticated API operations. EnablePropagateAdditionalUserContextData doesn't affect whether you can send a source IP address in a ContextData parameter with the authenticated API operations AdminInitiateAuth and AdminRespondToAuthChallenge.

You can only activate EnablePropagateAdditionalUserContextData in an app client that has a client secret. For more information about propagation of user context data, see Adding user device and session data to API requests.

AuthSessionValidity

integer

optional

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.

>= 3<= 15
