-- This operation retrieves the @notification-configuration@ subresource of the specified vault.
--
--
-- For information about setting a notification configuration on a vault, see 'SetVaultNotifications' . If a notification configuration for a vault is not set, the operation returns a @404 Not Found@ error. For more information about vault notifications, see <http://docs.aws.amazon.com/amazonglacier/latest/dev/configuring-notifications.html Configuring Vault Notifications in Amazon Glacier> .

-- An AWS account has full permission to perform all operations (actions). However, AWS Identity and Access Management (IAM) users don't have any permissions by default. You must grant them explicit permission to perform specific actions.
