Amazon Cognito - Admin Update User Attributes

See more Amazon Cognito Examples

Updates the specified user's attributes, including developer attributes, as an administrator. Works on any user.

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

In addition to updating user attributes, this API can also be used to mark phone and email as verified.
