AWS CLI Command Reference

[ aws . cognito-idp ]

admin-create-user

Description

Creates a new user in the specified user pool.

If MessageAction is not set, the default is to send a welcome message via email or phone (SMS).

Note

This action might generate an SMS text message. Starting June 1, 2021, U.S. telecom carriers require that you register an origination phone number before you can send SMS messages to U.S. phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint . Cognito will use the the registered number automatically. Otherwise, Cognito users that must receive SMS messages might be unable to sign up, activate their accounts, or sign in.

If you have never used SMS text messages with Amazon Cognito or any other Amazon Web Service, Amazon SNS might place your account in SMS sandbox. In * sandbox mode * , you’ll have limitations, such as sending messages to only verified phone numbers. After testing in the sandbox environment, you can move out of the SMS sandbox and into production. For more information, see SMS message settings for Cognito User Pools in the Amazon Cognito Developer Guide .

This message is based on a template that you configured in your call to create or update a user pool. This template includes your custom sign-up instructions and placeholders for user name and temporary password.

Alternatively, you can call AdminCreateUser with “SUPPRESS” for the MessageAction parameter, and Amazon Cognito will not send any email.

In either case, the user will be in the FORCE_CHANGE_PASSWORD state until they sign in and change their password.

AdminCreateUser requires developer credentials.

Options

--user-pool-id (string)

The user pool ID for the user pool where the user will be created.

--username (string)

The username for the user. Must be unique within the user pool. Must be a UTF-8 string between 1 and 128 characters. After the user is created, the username cannot be changed.

--user-attributes (list)

An array of name-value pairs that contain user attributes and attribute values to be set for the user to be created. You can create a user without specifying any attributes other than Username . However, any attributes that you specify as required (when creating a user pool or in the Attributes tab of the console) must be supplied either by you (in your call to AdminCreateUser ) or by the user (when he or she signs up in response to your welcome message).

For custom attributes, you must prepend the custom: prefix to the attribute name.

To send a message inviting the user to sign up, you must specify the user’s email address or phone number. This can be done in your call to AdminCreateUser or in the Users tab of the Amazon Cognito console for managing your user pools.

In your call to AdminCreateUser , you can set the email_verified attribute to True , and you can set the phone_number_verified attribute to True . (You can also do this by calling AdminUpdateUserAttributes .)

  • email : The email address of the user to whom the message that contains the code and username will be sent. Required if the email_verified attribute is set to True , or if "EMAIL" is specified in the DesiredDeliveryMediums parameter.

  • phone_number : The phone number of the user to whom the message that contains the code and username will be sent. Required if the phone_number_verified attribute is set to True , or if "SMS" is specified in the DesiredDeliveryMediums parameter.

(structure)

Specifies whether the attribute is standard or custom.

Name -> (string)

The name of the attribute.

Value -> (string)

The value of the attribute.

Shorthand Syntax:

Name=string,Value=string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Value": "string"
  }
  ...
]

--validation-data (list)

The user’s validation data. This is an array of name-value pairs that contain user attributes and attribute values that you can use for custom validation, such as restricting the types of user accounts that can be registered. For example, you might choose to allow or disallow user sign-up based on the user’s domain.

To configure custom validation, you must create a Pre Sign-up Lambda trigger for the user pool as described in the Amazon Cognito Developer Guide. The Lambda trigger receives the validation data and uses it in the validation process.

The user’s validation data is not persisted.

(structure)

Specifies whether the attribute is standard or custom.

Name -> (string)

The name of the attribute.

Value -> (string)

The value of the attribute.

Shorthand Syntax:

Name=string,Value=string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Value": "string"
  }
  ...
]

--temporary-password (string)

The user’s temporary password. This password must conform to the password policy that you specified when you created the user pool.

The temporary password is valid only once. To complete the Admin Create User flow, the user must enter the temporary password in the sign-in page along with a new password to be used in all future sign-ins.

This parameter is not required. If you do not specify a value, Amazon Cognito generates one for you.

The temporary password can only be used until the user account expiration limit that you specified when you created the user pool. To reset the account after that time limit, you must call AdminCreateUser again, specifying "RESEND" for the MessageAction parameter.

--force-alias-creation | --no-force-alias-creation (boolean)

This parameter is only used if the phone_number_verified or email_verified attribute is set to True . Otherwise, it is ignored.

If this parameter is set to True and the phone number or email address specified in the UserAttributes parameter already exists as an alias with a different user, the API call will migrate the alias from the previous user to the newly created user. The previous user will no longer be able to log in using that alias.

If this parameter is set to False , the API throws an AliasExistsException error if the alias already exists. The default value is False .

--message-action (string)

Set to "RESEND" to resend the invitation message to a user that already exists and reset the expiration limit on the user’s account. Set to "SUPPRESS" to suppress sending the message. Only one value can be specified.

Possible values:

  • RESEND

  • SUPPRESS

--desired-delivery-mediums (list)

Specify "EMAIL" if email will be used to send the welcome message. Specify "SMS" if the phone number will be used. The default value is "SMS" . More than one value can be specified.

(string)

Syntax:

"string" "string" ...

Where valid values are:
  SMS
  EMAIL

--client-metadata (map)

A map of custom key-value pairs that you can provide as input for any custom workflows that this action triggers.

You create custom workflows by assigning Lambda functions to user pool triggers. When you use the AdminCreateUser API action, Amazon Cognito invokes the function that is assigned to the pre sign-up trigger. When Amazon Cognito invokes this function, it passes a JSON payload, which the function receives as input. This payload contains a clientMetadata attribute, which provides the data that you assigned to the ClientMetadata parameter in your AdminCreateUser request. In your function code in Lambda, you can process the clientMetadata value to enhance your workflow for your specific needs.

For more information, see Customizing User Pool Workflows with Lambda Triggers in the Amazon Cognito Developer Guide .

Note

Take the following limitations into consideration when you use the ClientMetadata parameter:

  • Amazon Cognito does not store the ClientMetadata value. This data is available only to Lambda triggers that are assigned to a user pool to support custom workflows. If your user pool configuration does not include triggers, the ClientMetadata parameter serves no purpose.

  • Amazon Cognito does not validate the ClientMetadata value.

  • Amazon Cognito does not encrypt the the ClientMetadata value, so don’t use it to provide sensitive information.

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.
