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.
StartConfigurationSession , your code sends the following information:
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.
GetLatestConfiguration. You must use the new token in the
NextPollConfigurationToken) in each subsequent call to
GetLatestConfiguration , your client code sends the most recent
ConfigurationToken value it has and receives in response:
ConfigurationTokenvalue to use on the next call to
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
NextPollConfigurationTokenshould only be used once. To support long poll use cases, the tokens are valid for up to 24 hours. If a
GetLatestConfigurationcall uses an expired token, the system returns
