Request Syntax


GET /applications/Application/environments/Environment/configurations/Configuration?client_configuration_version=ClientConfigurationVersion&client_id=ClientId HTTP/1.1

URI Request Parameters

The request uses the following URI parameters.

Application

The application to get. Specify either the application name or the application ID.

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: Yes

ClientConfigurationVersion

The configuration version returned in the most recent GetConfiguration response.

Important

AWS 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 feature flags and configuration data in AWS AppConfig in the AWS AppConfig User Guide.

Length Constraints: Minimum length of 1. Maximum length of 1024.

ClientId

The clientId parameter in the following command is a unique, user-specified ID to identify the client for the configuration. This ID enables AWS AppConfig to deploy the configuration in intervals, as defined in the deployment strategy.

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: Yes

Configuration

The configuration to get. Specify either the configuration name or the configuration ID.

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: Yes
