# AWS::AppConfig::ConfigurationProfile Validators
<a name="aws-properties-appconfig-configurationprofile-validators"></a>

A validator provides a syntactic or semantic check to ensure the configuration that you want to deploy functions as intended. To validate your application configuration data, you provide a schema or an AWS Lambda function that runs against the configuration. The configuration deployment or update can only proceed when the configuration data is valid. For more information, see [About validators](https://docs.aws.amazon.com/appconfig/latest/userguide/appconfig-creating-configuration-profile.html#appconfig-creating-configuration-and-profile-validators) in the *AWS AppConfig User Guide*.
