CreateUserPool

Note

This action might generate an SMS text message. Starting June 1, 2021, US telecom carriers require you to register an origination phone number before you can send SMS messages to US phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint. Amazon Cognito uses the registered number automatically. Otherwise, Amazon Cognito users who must receive SMS messages might not be able to sign up, activate their accounts, or sign in.

If you have never used SMS text messages with Amazon Cognito or any other AWS service, Amazon Simple Notification Service might place your account in the SMS sandbox. In sandbox mode , you can send messages only to verified phone numbers. After you test your app while in the sandbox environment, you can move out of the sandbox and into production. For more information, see SMS message settings for Amazon Cognito user pools in the Amazon Cognito Developer Guide.

Creates a new Amazon Cognito user pool and sets the password policy for the pool.

Important

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

Note

Amazon Cognito evaluates AWS 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.

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.

AccountRecoverySetting

The available verified method a user can use to recover their password when they call ForgotPassword. You can use this setting to define a preferred method when a user has more than one method available. With this setting, SMS doesn't qualify for a valid password recovery mechanism if the user also has SMS multi-factor authentication (MFA) activated. In the absence of this setting, Amazon Cognito uses the legacy behavior to determine the recovery method where SMS is preferred through email.

Type: AccountRecoverySettingType object

Required: No

AdminCreateUserConfig

The configuration for AdminCreateUser requests.

Type: AdminCreateUserConfigType object

Required: No

AliasAttributes

Attributes supported as an alias for this user pool. Possible values: phone_number, email, or preferred_username.

Type: Array of strings

Valid Values: phone_number | email | preferred_username

Required: No

AutoVerifiedAttributes

The attributes to be auto-verified. Possible values: email, phone_number.

Type: Array of strings

Valid Values: phone_number | email

Required: No

DeletionProtection

When active, DeletionProtection prevents accidental deletion of your user pool. Before you can delete a user pool that you have protected against deletion, you must deactivate this feature.

When you try to delete a protected user pool in a DeleteUserPool API request, Amazon Cognito returns an InvalidParameterException error. To delete a protected user pool, send a new DeleteUserPool request after you deactivate deletion protection in an UpdateUserPool API request.

Type: String

Valid Values: ACTIVE | INACTIVE

Required: No

DeviceConfiguration

The device-remembering configuration for a user pool. A null value indicates that you have deactivated device remembering in your user pool.

Note

When you provide a value for any DeviceConfiguration field, you activate the Amazon Cognito device-remembering feature.

Type: DeviceConfigurationType object

Required: No

EmailConfiguration

The email configuration of your user pool. The email configuration type sets your preferred sending method, AWS Region, and sender for messages from your user pool.

Type: EmailConfigurationType object

Required: No

EmailVerificationMessage

This parameter is no longer used. See VerificationMessageTemplateType.

Type: String

Length Constraints: Minimum length of 6. Maximum length of 20000.

Pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}\s*]*\{####\}[\p{L}\p{M}\p{S}\p{N}\p{P}\s*]*

Required: No

EmailVerificationSubject

This parameter is no longer used. See VerificationMessageTemplateType.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 140.

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

Required: No

LambdaConfig

A collection of user pool Lambda triggers. Amazon Cognito invokes triggers at several possible stages of authentication operations. Triggers can modify the outcome of the operations that invoked them.

Type: LambdaConfigType object

Required: No

MfaConfiguration

Specifies MFA configuration details.

Type: String

Valid Values: OFF | ON | OPTIONAL

Required: No

Policies

The policies associated with the new user pool.

Type: UserPoolPolicyType object

Required: No

PoolName

A string used to name the user pool.

Type: String

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

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

Required: Yes

Schema

An array of schema attributes for the new user pool. These attributes can be standard or custom attributes.

Type: Array of SchemaAttributeType objects

Array Members: Minimum number of 1 item. Maximum number of 50 items.

Required: No

SmsAuthenticationMessage

A string representing the SMS authentication message.

Type: String

Length Constraints: Minimum length of 6. Maximum length of 140.

Pattern: .*\{####\}.*

Required: No

SmsConfiguration

The SMS configuration with the settings that your Amazon Cognito user pool must use to send an SMS message from your AWS account through Amazon Simple Notification Service. To send SMS messages with Amazon SNS in the AWS Region that you want, the Amazon Cognito user pool uses an AWS Identity and Access Management (IAM) role in your AWS account.

Type: SmsConfigurationType object

Required: No

SmsVerificationMessage

This parameter is no longer used. See VerificationMessageTemplateType.

Type: String

Length Constraints: Minimum length of 6. Maximum length of 140.

Pattern: .*\{####\}.*

Required: No

UserAttributeUpdateSettings

The settings for updates to user attributes. These settings include the property AttributesRequireVerificationBeforeUpdate, a user-pool setting that tells Amazon Cognito how to handle changes to the value of your users' email address and phone number attributes. For more information, see Verifying updates to email addresses and phone numbers.

Type: UserAttributeUpdateSettingsType object

Required: No

UsernameAttributes

Specifies whether a user can use an email address or phone number as a username when they sign up.

Type: Array of strings

Valid Values: phone_number | email

Required: No

UsernameConfiguration

Case sensitivity on the username input for the selected sign-in option. When case sensitivity is set to False (case insensitive), users can sign in with any combination of capital and lowercase letters. For example, username, USERNAME, or UserName, or for email, email@example.com or EMaiL@eXamplE.Com. For most use cases, set case sensitivity to False (case insensitive) as a best practice. When usernames and email addresses are case insensitive, Amazon Cognito treats any variation in case as the same user, and prevents a case variation from being assigned to the same attribute for a different user.

This configuration is immutable after you set it. For more information, see UsernameConfigurationType.

Type: UsernameConfigurationType object

Required: No

UserPoolAddOns

User pool add-ons. Contains settings for activation of advanced security features. To log user security information but take no action, set to AUDIT. To configure automatic security responses to risky traffic to your user pool, set to ENFORCED.

For more information, see Adding advanced security to a user pool.

Type: UserPoolAddOnsType object

Required: No

UserPoolTags

The tag keys and values to assign to the user pool. A tag is a label that you can use to categorize and manage user pools in different ways, such as by purpose, owner, environment, or other criteria.

Type: String to string map

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

Value Length Constraints: Minimum length of 0. Maximum length of 256.

Required: No

VerificationMessageTemplate

The template for the verification message that your user pool delivers to users who set an email address or phone number attribute.

Set the email message type that corresponds to your DefaultEmailOption selection. For CONFIRM_WITH_LINK, specify an EmailMessageByLink and leave EmailMessage blank. For CONFIRM_WITH_CODE, specify an EmailMessage and leave EmailMessageByLink blank. When you supply both parameters with either choice, Amazon Cognito returns an error.

Type: VerificationMessageTemplateType object

Required: No
