get-user-attribute-verification-code

Description

Gets the user attribute verification code for the specified attribute name.

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 .

Synopsis

  get-user-attribute-verification-code
--access-token <value>
--attribute-name <value>
[--client-metadata <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--access-token (string)

The access token returned by the server response to get the user attribute verification code.

--attribute-name (string)

The attribute name returned by the server response to get the user attribute verification code.

--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 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 .

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.

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.
