Synopsis

Calls the Amazon Cognito Identity Provider GetUserAttributeVerificationCode API operation. This operation uses anonymous authentication and does not require credential parameters to be supplied.

Syntax

Get-CGIPUserAttributeVerificationCode
-AccessToken <String>
-AttributeName <String>
-ClientMetadata <Hashtable>
-Select <String>
-ClientConfig <AmazonCognitoIdentityProviderConfig>

Description

Generates a user attribute verification code for the specified attribute name. Sends a message to a user with a code that they must return in a VerifyUserAttribute request. Authorize this action with a signed-in user's access token. It must include the scope aws.cognito.signin.user.admin. Amazon Cognito doesn't evaluate Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you can't use IAM credentials to authorize requests, and you can't grant IAM permissions in policies. For more information about authorization models in Amazon Cognito, see Using the Amazon Cognito user pools API and user pool endpoints. 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 Services 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.

Parameters

-AccessToken <String>
A non-expired access token for the user whose attribute verification code you want to generate.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-AttributeName <String>
The attribute name returned by the server response to get the user attribute verification code.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClientConfig <AmazonCognitoIdentityProviderConfig>
Amazon.PowerShell.Cmdlets.CGIP.AnonymousAmazonCognitoIdentityProviderClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClientMetadata <Hashtable>
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 GetUserAttributeVerificationCode API action, Amazon Cognito invokes the function that is assigned to the custom message 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 GetUserAttributeVerificationCode 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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'CodeDeliveryDetails'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.CognitoIdentityProvider.Model.GetUserAttributeVerificationCodeResponse). Specifying the name of a property of type Amazon.CognitoIdentityProvider.Model.GetUserAttributeVerificationCodeResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs). When supplied the cmdlet will attempt to read the default region to be used from the credential file's default profile.If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?212
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.If the Region parameter is supplied the cmdlet ignores the ProfileLocation parameter.
Required?False
Position?211
Accept pipeline input?True (ByValue, ByPropertyName)
AliasesRegionToCall

Outputs

Amazon.CognitoIdentityProvider.Model.CodeDeliveryDetailsType or Amazon.CognitoIdentityProvider.Model.GetUserAttributeVerificationCodeResponse
This cmdlet returns an Amazon.CognitoIdentityProvider.Model.CodeDeliveryDetailsType object. The service call response (type Amazon.CognitoIdentityProvider.Model.GetUserAttributeVerificationCodeResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
