Create User Pool Client

cognitoidentityprovider_create_user_pool_client

R Documentation

Creates the user pool client

Description

Creates the user pool client.

When you create a new user pool client, token revocation is automatically activated. For more information about revoking tokens, see revoke_token.

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

Amazon Cognito evaluates 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.

Arguments

UserPoolId

[required] The user pool ID for the user pool where you want to create a user pool client.

ClientName

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

GenerateSecret

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

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.

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.

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.

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.

ReadAttributes

The list of user attributes that you want your app client to have read-only 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 get_user 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 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.

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 update_user_attributes 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.

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.

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_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.

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.

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.

LogoutURLs

A list of allowed logout URLs for the IdPs.

DefaultRedirectURI

The default redirect URI. In app clients with one assigned IdP, replaces redirect_uri in authentication requests. 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.

For more information, see Default redirect URI.

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

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

AllowedOAuthFlows

The OAuth grant types that you want your app client to generate. To create an app client that generates client credentials grants, you must add client_credentials as the only allowed OAuth flow.

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.

AllowedOAuthScopes

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

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 create_user_pool_client or update_user_pool_client API request. If you don't set a value for AllowedOAuthFlowsUserPoolClient in a request with the CLI or SDKs, it defaults to false.

AnalyticsConfiguration

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

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

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.

EnableTokenRevocation

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

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

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.

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.
