clientConfigurationVersion

The configuration version returned in the most recent GetConfiguration response.

AppConfig uses the value of the ClientConfigurationVersion parameter to identify the configuration version on your clients. If you don’t send ClientConfigurationVersion with each call to GetConfiguration, your clients receive the current configuration. You are charged each time your clients receive a configuration.

To avoid excess charges, we recommend you use the StartConfigurationSession and GetLatestConfiguration APIs, which track the client configuration version on your behalf. If you choose to continue using GetConfiguration, we recommend that you include the ClientConfigurationVersion value with every call to GetConfiguration. The value to use for ClientConfigurationVersion comes from the ConfigurationVersion attribute returned by GetConfiguration when there is new or updated data, and should be saved for subsequent calls to GetConfiguration.

For more information about working with configurations, see Retrieving the Configuration in the AppConfig User Guide.
