AppConfigData

Installation

To install the AppConfigData client:

python -m pip install aws-sdk-appconfigdata

Client

AsyncAppConfigDataClient

Bases: AsyncClient[AsyncAppConfigDataConfig]

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.

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.

  • The configuration: the latest data intended for the session. This may be empty if the client already has the latest version of the configuration.

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.

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 in the AppConfig User Guide.

Attributes

auth_scheme_resolver class-attribute instance-attribute 
auth_scheme_resolver: AuthSchemeResolver | None = None

An auth scheme resolver that determines the auth scheme for each operation.

auth_schemes class-attribute instance-attribute 
auth_schemes: dict[ShapeID, AsyncAuthScheme[Any, Any, Any, Any]] | None = None

A map of auth scheme ids to auth schemes.

aws_access_key_id class-attribute instance-attribute 
aws_access_key_id: str | None = None

The identifier for a secret access key.

aws_credentials_identity_resolver class-attribute instance-attribute 
aws_credentials_identity_resolver: AsyncIdentityResolver[AWSCredentialsIdentity, AWSIdentityProperties] | None = None

Resolves AWS Credentials. Required for operations that use Sigv4 Auth.

aws_secret_access_key class-attribute instance-attribute 
aws_secret_access_key: str | None = None

A secret access key that can be used to sign requests.

aws_session_token class-attribute instance-attribute 
aws_session_token: str | None = None

The session token used with temporary AWS credentials.

endpoint_resolver class-attribute instance-attribute 
endpoint_resolver: EndpointResolver | AsyncEndpointResolver | None = None

The endpoint resolver used to resolve the final endpoint per-operation based on the configuration.

interceptors class-attribute instance-attribute 
interceptors: list[_ServiceInterceptor] = field(default_factory=lambda: [])

The list of interceptors, which are hooks that are called during the execution of a request.

protocol class-attribute instance-attribute 
protocol: ClientProtocol[Any, Any] | None = None

Pass a protocol class reference from smithy_aws_core.aio.protocols to select the protocol, e.g. protocol=AsyncAwsJson10ClientProtocol. For custom protocols a protocol instance may also be passed.

region class-attribute instance-attribute 
region: str | None = None

The AWS region to connect to. The configured region is used to determine the service endpoint.

sdk_ua_app_id class-attribute instance-attribute 
sdk_ua_app_id: str | None = None

A unique and opaque application ID that is appended to the User-Agent header.

use_dualstack_endpoint class-attribute instance-attribute 
use_dualstack_endpoint: bool | None = None

When true, use the dual-stack endpoint. If the configured endpoint does not support dual-stack, dispatching the request MAY return an error.

use_fips_endpoint class-attribute instance-attribute 
use_fips_endpoint: bool | None = None

When true, send this request to the FIPS-compliant regional endpoint. If the configured endpoint does not have a FIPS compliant endpoint, dispatching the request will return an error.

user_agent_extra class-attribute instance-attribute 
user_agent_extra: str | None = None

Additional suffix to be added to the User-Agent header.

Methods:

resolve async classmethod 
resolve(*, profile: str | None = None, fs: AsyncFileSystem | None = None, config_file_path: str | None = None, credentials_file_path: str | None = None, **overrides: Unpack[_AsyncAppConfigDataConfigOverrides]) -> Self

Resolve config from environment, config files, defaults, and explicit overrides.

set_auth_scheme 
set_auth_scheme(scheme: AsyncAuthScheme[Any, Any, Any, Any]) -> None

Set an auth scheme implementation using its scheme ID. :param scheme: The auth scheme to add or replace.

Plugin module-attribute 

Plugin: TypeAlias = Callable[[AsyncAppConfigDataConfig], None]

A callable that customizes a client configuration. Service-level plugins are applied once to the base configuration inherited by every operation. Operation-level plugins apply only to a single operation invocation.
