update_user_attributes

CognitoIdentityProvider.Client.update_user_attributes(**kwargs)

Allows a user to update a specific attribute (one at a time).

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 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 .

Request Syntax

response = client.update_user_attributes(
    UserAttributes=[
        {
            'Name': 'string',
            'Value': 'string'
        },
    ],
    AccessToken='string',
    ClientMetadata={
        'string': 'string'
    }
)

Parameters

• UserAttributes (list) --

  [REQUIRED]

  An array of name-value pairs representing user attributes.

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

  If you have set an attribute to require verification before Amazon Cognito updates its value, this request doesn’t immediately update the value of that attribute. After your user receives and responds to a verification message to verify the new value, Amazon Cognito updates the attribute value. Your user can sign in and receive messages with the original attribute value until they verify the new value.

  • (dict) --

    Specifies whether the attribute is standard or custom.

    • Name (string) -- [REQUIRED]

      The name of the attribute.

    • Value (string) --

      The value of the attribute.

• AccessToken (string) --

  [REQUIRED]

  A valid access token that Amazon Cognito issued to the user whose user attributes you want to update.

• ClientMetadata (dict) --

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

  You create custom workflows by assigning Lambda functions to user pool triggers. When you use the UpdateUserAttributes 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 UpdateUserAttributes 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

  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.
