Implements IConstruct, IDependable, IInspectable

A CloudFormation AWS::Cognito::UserPoolClient.

The AWS::Cognito::UserPoolClient resource specifies an Amazon Cognito user pool client.

If you don't specify a value for a parameter, Amazon Cognito sets it to a default value.

Example

import { aws_certificatemanager as acm } from 'aws-cdk-lib';

declare const vpc: ec2.Vpc;
declare const certificate: acm.Certificate;

const lb = new elbv2.ApplicationLoadBalancer(this, 'LB', {

userPoolId

Type: string

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


accessTokenValidity?

Type: number (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.


allowedOAuthFlows?

Type: 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.

allowedOAuthFlowsUserPoolClient?

Type: boolean | IResolvable (optional)

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


allowedOAuthScopes?

Type: string[] (optional)

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.


analyticsConfiguration?

Type: IResolvable | AnalyticsConfigurationProperty (optional)

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

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


authSessionValidity?

Type: number (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.


callbackUrLs?

Type: 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.


clientName?

Type: string (optional)

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


defaultRedirectUri?

Type: 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.


enablePropagateAdditionalUserContextData?

Type: boolean | IResolvable (optional)

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.


enableTokenRevocation?

Type: boolean | IResolvable (optional)

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.


explicitAuthFlows?

Type: 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.

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 .


generateSecret?

Type: boolean | IResolvable (optional)

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


idTokenValidity?

Type: number (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 IdTokenValidity in an API request is hours.


logoutUrLs?

Type: string[] (optional)

A list of allowed logout URLs for the IdPs.


preventUserExistenceErrors?

Type: string (optional)

Use this setting to choose which errors and responses are returned by Cognito APIs during authentication, account confirmation, and password recovery when the user does not exist in the user pool.

When set to ENABLED and the user does not exist, authentication returns an error indicating either the username or password was incorrect, and account confirmation and password recovery return a response indicating a code was sent to a simulated destination. When set to LEGACY , those APIs will return a UserNotFoundException exception if the user does not exist in the user pool.


readAttributes?

Type: string[] (optional)

The read attributes.


refreshTokenValidity?

Type: number (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.


supportedIdentityProviders?

Type: string[] (optional)

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 .


tokenValidityUnits?

Type: IResolvable | TokenValidityUnitsProperty (optional)

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.


writeAttributes?

Type: string[] (optional)

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 .

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

  • path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).


addDependency(target)

public addDependency(target: CfnResource): void

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.


addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.


addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

  • key string
  • value any

Add a value to the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)


addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

  • path string — - The path of the property, you can use dot notation to override values in complex types.
  • value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.


addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

  • propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.


addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

  • propertyPath string — The path of the property.
  • value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).


applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

  • policy RemovalPolicy
  • options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

See also: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options


getAtt(attributeName, typeHint?)

public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference

Parameters

  • attributeName string — The name of the attribute.
  • typeHint ResolutionTypeHint

Returns

  • Reference

getMetadata(key)

public getMetadata(key: string): any

Parameters

  • key string

Returns

  • any

Retrieve a value value from the CloudFormation Resource Metadata.

Overrides the auto-generated logical ID with a specific ID.


removeDependency(target)

public removeDependency(target: CfnResource): void

Parameters

  • target CfnResource

Indicates that this resource no longer depends on another resource.

This can be used for resources across stacks (including nested stacks) and the dependency will automatically be removed from the relevant scope.


replaceDependency(target, newTarget)

public replaceDependency(target: CfnResource, newTarget: CfnResource): void

Parameters

  • target CfnResource — The dependency to replace.
  • newTarget CfnResource — The new dependency to add.

Replaces one dependency with another.
