// Package appconfigdata provides the API client, operations, and parameter types
// for AWS AppConfig Data.
//
// AppConfig Data provides the data plane APIs your application uses to retrieve
// configuration data. Here's how it works: Your application retrieves
// configuration data by first establishing a configuration session using the
// AppConfig Data StartConfigurationSession API action. Your session's client then
// makes periodic calls to GetLatestConfiguration to check for and retrieve the
// latest data available. When calling StartConfigurationSession , your code sends
// the following information:
//   - Identifiers (ID or name) of an AppConfig application, environment, and
//     configuration profile that the session tracks.
//   - (Optional) The minimum amount of time the session's client must wait
//     between calls to GetLatestConfiguration .
//
// In response, AppConfig provides an InitialConfigurationToken to be given to the
// session's client and used the first time it calls GetLatestConfiguration for
// that session. This token should only be used once in your first call to
// GetLatestConfiguration . You must use the new token in the
// GetLatestConfiguration response ( NextPollConfigurationToken ) in each
// subsequent call to GetLatestConfiguration . When calling GetLatestConfiguration
// , your client code sends the most recent ConfigurationToken value it has and
// receives in response:
//   - NextPollConfigurationToken : the ConfigurationToken value to use on the next
//     call to GetLatestConfiguration .
//   - NextPollIntervalInSeconds : the duration the client should wait before
//     making its next call to GetLatestConfiguration . This duration may vary over
//     the course of the session, so it should be used instead of the value sent on the
//     StartConfigurationSession call.
//   - The configuration: the latest data intended for the session. This may be
//     empty if the client already has the latest version of the configuration.
//
// The InitialConfigurationToken and NextPollConfigurationToken should only be
// used once. To support long poll use cases, the tokens are valid for up to 24
// hours. If a GetLatestConfiguration call uses an expired token, the system
// returns BadRequestException . For more information and to view example CLI
// commands that show how to retrieve a configuration using the AppConfig Data
// StartConfigurationSession and GetLatestConfiguration API actions, see
// Retrieving the configuration (http://docs.aws.amazon.com/appconfig/latest/userguide/appconfig-retrieving-the-configuration)
// in the AppConfig User Guide.
