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.

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

Type: Boolean

Required: No

AllowedOAuthScopes

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

AnalyticsConfiguration

The user pool analytics configuration for collecting metrics and sending them to your Amazon Pinpoint campaign.

Note

In Amazon Regions where Amazon Pinpoint isn't available, user pools only support sending events to Amazon Pinpoint projects in Amazon Region 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

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}]+

Required: No

ClientName

The client name for the user pool client you would like to create.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [\w\s+=,.@-]+

Required: Yes

DefaultRedirectURI

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.

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.

If you don't include this parameter, token revocation is automatically activated for the new user pool client.

Type: Boolean

Required: No

ExplicitAuthFlows

The authentication flows that are supported by the user pool clients. Flow names without the ALLOW_ prefix are no longer supported, in favor of new names with the ALLOW_ prefix.

Note

Values with ALLOW_ prefix must be used only along with the ALLOW_ prefix.

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, Amazon Cognito receives the password in the request instead of using the Secure Remote Password (SRP) protocol to verify passwords.
ALLOW_CUSTOM_AUTH: Enable Amazon 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 the authflow that refreshes tokens.

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

Type: Array of strings

Required: No

GenerateSecret

Boolean to specify whether you want to generate a secret for the user pool client being created.

Type: Boolean

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 AccessTokenValidity in an API request is hours. Valid range is displayed below in seconds.

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.

This setting affects the behavior of following APIs:

Type: String

Valid Values: LEGACY | ENABLED

Required: No

ReadAttributes

The 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.

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.

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}]+

Required: No

TokenValidityUnits

The units in which the validity times are represented. The default unit for RefreshToken is days, and default for ID and access tokens are hours.

Type: TokenValidityUnitsType object

Required: No

UserPoolId

The user pool ID for the user pool where you want to create a 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 user pool attributes that the app client can write to.

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
