Class IAMCredentialsAsyncClient (2.0.0)

IAMCredentialsAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.iam_credentials_v1.services.iam_credentials.transports.base.IAMCredentialsTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/python-iam/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None)

A service account is a special type of Google account that belongs to your application or a virtual machine (VM), instead of to an individual end user. Your application assumes the identity of the service account to call Google APIs, so that the users aren't directly involved.

Service account credentials are used to temporarily assume the identity of the service account. Supported credential types include OAuth 2.0 access tokens, OpenID Connect ID tokens, self- signed JSON Web Tokens (JWTs), and more.

Methods

IAMCredentialsAsyncClient

IAMCredentialsAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.iam_credentials_v1.services.iam_credentials.transports.base.IAMCredentialsTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/python-iam/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None)

Instantiate the iam credentials client.

Parameters
NameDescription
credentials Optional[google.auth.credentials.Credentials]

The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.

transport Union[str, .IAMCredentialsTransport]

The transport to use. If set to None, a transport is chosen automatically.

client_options ClientOptions

Custom options for the client. It won't take effect if a transport instance is provided. (1) The api_endpoint property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint, this is the default value for the environment variable) and "auto" (auto switch to the default mTLS endpoint if client SSL credentials is present). However, the api_endpoint property takes precedence if provided. (2) The client_cert_source property is used to provide client SSL credentials for mutual TLS transport. If not provided, the default SSL credentials will be used if present.

Exceptions
TypeDescription
google.auth.exceptions.MutualTlsChannelErrorIf mutual TLS transport creation failed for any reason.

from_service_account_file

from_service_account_file(filename: str, *args, **kwargs)

Returns
TypeDescription
{@api.name}The constructed client.

from_service_account_json

from_service_account_json(filename: str, *args, **kwargs)

Creates an instance of this client using the provided credentials file.

Parameter
NameDescription

lifetime .duration.Duration

The desired lifetime duration of the access token in seconds. Must be set to a value less than or equal to 3600 (1 hour).
