AppConfigData.
Client
¶A low-level client representing 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:
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.
Warning
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.Warning
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
.

and GetLatestConfiguration
API actions, see Retrieving the configuration in the AppConfig User Guide .
