Verifies the specified user attributes in the user pool.

If your user pool requires verification before Amazon Cognito updates the attribute value, VerifyUserAttribute updates the affected attribute to its pending value. For more information, see UserAttributeUpdateSettingsType.

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.

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginVerifyUserAttribute and EndVerifyUserAttribute.
