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.
When calling GetLatestConfiguration
, your client code sends the most recent
ConfigurationToken
value it has and receives in response:
NextPollConfigurationToken
: theConfigurationToken
value to use on the next call toGetLatestConfiguration
.NextPollIntervalInSeconds
: the duration the client should wait before making its next call toGetLatestConfiguration
. This duration may vary over the course of the session, so it should be used instead of the value sent on theStartConfigurationSession
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.

a configuration using the AppConfig Data StartConfigurationSession

View SourceRetrieves the latest deployed configuration.
This API may return empty configuration data if the client already has the
latest version. For more information about this API action and to view example
CLI commands that show how to use it with the StartConfigurationSession
API
action, see Receiving the configuration
in the AppConfig User Guide.
Note the following important information.
Each configuration token is only valid for one call to
GetLatestConfiguration
. The GetLatestConfiguration
response includes a
NextPollConfigurationToken
that should always replace the token used for the
just-completed call in preparation for the next one.
GetLatestConfiguration
is a priced call. For more information,
