Container for the parameters to the AdminCreateUser operation. Creates a new user in the specified user pool.

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

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 Amazon Web 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.

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 won't send any email.

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

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.

Public Method AdminCreateUserRequest()

Properties

NameTypeDescription
Public Property ClientMetadata System.Collections.Generic.Dictionary<System.String, System.String>

Gets and sets the property ClientMetadata.

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.

When you use the ClientMetadata parameter, remember that Amazon Cognito won't do the following:

  • 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 doesn't include triggers, the ClientMetadata parameter serves no purpose.

  • Validate the ClientMetadata value.

  • Encrypt the ClientMetadata value. Don't use Amazon Cognito to provide sensitive information.

Public Property DesiredDeliveryMediums System.Collections.Generic.List<System.String>

Gets and sets the property DesiredDeliveryMediums.

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". You can specify more than one value.

Public Property ForceAliasCreation System.Boolean

Gets and sets the property ForceAliasCreation.

This parameter is used only 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.

Public Property MessageAction Amazon.CognitoIdentityProvider.MessageActionType

Gets and sets the property MessageAction.

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. You can specify only one value.

Public Property TemporaryPassword System.String

Gets and sets the property TemporaryPassword.

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 isn't required. If you don't specify a value, Amazon Cognito generates one for you.

The temporary password can only be used until the user account expiration limit that you set for your user pool. To reset the account after that time limit, you must call AdminCreateUser again and specify RESEND for the MessageAction parameter.

Public Property UserAttributes System.Collections.Generic.List<Amazon.CognitoIdentityProvider.Model.AttributeType>

Gets and sets the property UserAttributes.

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) either you should supply (in your call to AdminCreateUser) or the user should supply (when they sign 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. You can do this 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.

Public Property Username System.String

Gets and sets the property Username.

The value that you want to set as the username sign-in attribute. The following conditions apply to the username parameter.

  • The username can't be a duplicate of another username in the same user pool.

  • You can't change the value of a username after you create it.

  • You can only provide a value if usernames are a valid sign-in attribute for your user pool. If your user pool only supports phone numbers or email addresses as sign-in attributes, Amazon Cognito automatically generates a username value. For more information, see Customizing sign-in attributes.

Public Property UserPoolId System.String

Gets and sets the property UserPoolId.

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

Public Property ValidationData System.Collections.Generic.List<Amazon.CognitoIdentityProvider.Model.AttributeType>

Gets and sets the property ValidationData.

Temporary user attributes that contribute to the outcomes of your pre sign-up Lambda trigger. This set of key-value pairs are for custom validation of information that you collect from your users but don't need to retain.

Your Lambda function can analyze this additional data and act on it. Your function might perform external API operations like logging user attributes and validation data to Amazon CloudWatch Logs. Validation data might also affect the response that your function returns to Amazon Cognito, like automatically confirming the user if they sign up from within your network.

For more information about the pre sign-up Lambda trigger, see Pre sign-up Lambda trigger.

Examples

This request submits a value for all possible parameters for AdminCreateUser.

An AdminCreateUser request for for a test user named John.


var client = new AmazonCognitoIdentityProviderClient();
var response = client.AdminCreateUser(new AdminCreateUserRequest 
{
    DesiredDeliveryMediums = new List<string> {
        "SMS"
    },
    MessageAction = "SUPPRESS",
    TemporaryPassword = "This-is-my-test-99!",
    UserAttributes = new List<AttributeType> {
        new AttributeType {
            Name = "name",
            Value = "John"
        },
        new AttributeType {
            Name = "phone_number",
            Value = "+12065551212"
        },
        new AttributeType {
            Name = "email",
            Value = "testuser@example.com"
        }
    },
    UserPoolId = "us-east-1_EXAMPLE",
    Username = "testuser"
});

UserType user = response.User;
