The AWS::Cognito::UserPoolDomain resource creates a new domain for a user pool.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "Type" : "AWS::Cognito::UserPoolDomain",
  "Properties" : {
      "CustomDomainConfig" : CustomDomainConfigType,
      "Domain" : String,
      "ManagedLoginVersion" : Integer,
      "UserPoolId" : String
    }
}

YAML

Type: AWS::Cognito::UserPoolDomain
Properties:
  CustomDomainConfig: 
    CustomDomainConfigType
  Domain: String
  ManagedLoginVersion: Integer
  UserPoolId: String

Properties

CustomDomainConfig

The configuration for a custom domain that hosts the sign-up and sign-in pages for your application. Use this object to specify an SSL certificate that is managed by ACM.

When you create a custom domain, the passkey RP ID defaults to the custom domain. If you had a prefix domain active, this will cause passkey integration for your prefix domain to stop working due to a mismatch in RP ID. To keep the prefix domain passkey integration working, you can explicitly set RP ID to the prefix domain.

Required: No

Type: CustomDomainConfigType

Update requires: No interruption

Domain

The name of the domain that you want to update. For custom domains, this is the fully-qualified domain name, for example auth.example.com. For prefix domains, this is the prefix alone, such as myprefix.

Required: Yes

Type: String

Pattern: ^[a-z0-9](?:[a-z0-9\-]{0,61}[a-z0-9])?$

Minimum: 1

Maximum: 63

ManagedLoginVersion

A version number that indicates the state of managed login for your domain. Version 1 is hosted UI (classic). Version 2 is the newer managed login with the branding designer. For more information, see Managed login.

Required: No

Type: Integer

Update requires: No interruption

UserPoolId

The ID of the user pool that is associated with the domain you're updating.

Required: Yes

Minimum: 1

Maximum: 55

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns physicalResourceId, which is “Domain". For example:

{ "Ref": "your-test-domain" }

For the Amazon Cognito user pool domain your-test-domain, Ref returns the name of the user pool domain.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

CloudFrontDistribution

The Amazon CloudFront endpoint that you use as the target of the alias that you set up with your Domain Name Service (DNS) provider.
