Constructors

Methods

Constructors

__init__

  • __init__(configuration, *, configure_logging): None

  • Create an Actor instance.

    Note that you don't have to do this, all the functionality is accessible using the default instance (e.g. Actor.open_dataset()).

    Parameters

    • configuration: Configuration | None = None

      The Actor configuration to be used. If not passed, a new Configuration instance will be created.

    • keyword-onlyconfigure_logging: bool = True

      Should the default logging configuration be configured?

    Returns None

Methods

__call__

  • __call__(configuration, *, configure_logging): Self

  • Make a new Actor instance with a non-default configuration.

    Parameters

    • configuration: Configuration | None = None
    • keyword-onlyconfigure_logging: bool = True

    Returns Self

__repr__

  • __repr__(): str

  • Returns str

abort

  • async abort(run_id, *, token, status_message, gracefully): ActorRun

  • Abort given Actor run on the Apify platform using the current user account.

    The user account is determined by the APIFY_TOKEN environment variable.

    Parameters

    • run_id: str

      The ID of the Actor run to be aborted.

    • keyword-onlytoken: str | None = None

      The Apify API token to use for this request (defaults to the APIFY_TOKEN environment variable).

    • keyword-onlystatus_message: str | None = None

      Status message of the Actor to be set on the platform.

    • keyword-onlygracefully: bool | None = None

      If True, the Actor run will abort gracefully. It will send aborting and persistState events into the run and force-stop the run after 30 seconds. It is helpful in cases where you plan to resurrect the run later.

    Returns ActorRun

    Info about the aborted Actor run.

add_webhook

  • async add_webhook(webhook, *, ignore_ssl_errors, do_not_retry, idempotency_key): None

  • Create an ad-hoc webhook for the current Actor run.

    This webhook lets you receive a notification when the Actor run finished or failed.

    Note that webhooks are only supported for Actors running on the Apify platform. When running the Actor locally, the function will print a warning and have no effect.

    For more information about Apify Actor webhooks, please see the documentation.

    Parameters

    • webhook: Webhook

      The webhook to be added

    • keyword-onlyignore_ssl_errors: bool | None = None

      Whether the webhook should ignore SSL errors returned by request_url

      Whether the webhook should retry sending the payload to request_url upon failure.

    • keyword-onlyidempotency_key: str | None = None

      A unique identifier of a webhook. You can use it to ensure that you won't create the same webhook multiple times.

    Returns None

    The created webhook.

    This stops the Actor instance. It cancels all the intervals for regularly sending PERSIST_STATE events, sends a final PERSIST_STATE event, waits for all the event listeners to finish, and stops the event manager.

    Parameters

    • keyword-onlyexit_code: int = 0

      The exit code with which the Actor should fail (defaults to 0).

    • keyword-onlyevent_listeners_timeout: timedelta | None = EVENT_LISTENERS_TIMEOUT

    • keyword-onlystatus_message: str | None = None

      The final status message that the Actor should display.

    • keyword-onlycleanup_timeout: timedelta = timedelta(seconds=30)

      How long we should wait for event listeners.

    Returns None

fail

  • async fail(*, exit_code, exception, status_message): None

  • Fail the Actor instance.

    This performs all the same steps as Actor.exit(), but it additionally sets the exit code to 1 (by default).

    Parameters

    • keyword-onlyexit_code: int = 1

      The exit code with which the Actor should fail (defaults to 1).

    • keyword-onlyexception: BaseException | None = None

      The exception with which the Actor failed.

    • keyword-onlystatus_message: str | None = None

      The final status message that the Actor should display.

    Returns None

get_env

  • get_env(): dict

  • Return a dictionary with information parsed from all the APIFY_XXX environment variables.

    For a list of all the environment variables, see the Actor documentation. If some variables are not defined or are invalid, the corresponding value in the resulting dictionary will be None.

    Returns dict

get_input

  • async get_input(): Any

  • Get the Actor input value from the default key-value store associated with the current Actor run.

    Returns Any

get_value

  • async get_value(key, default_value): Any

  • Get a value from the default key-value store associated with the current Actor run.

    Parameters

    • key: str

    • default_value: Any = None

      Default value returned in case the record does not exist.

    Returns Any

init

  • async init(): None

  • Initialize the Actor instance.

    This initializes the Actor instance. It configures the right storage client based on whether the Actor is running locally or on the Apify platform, it initializes the event manager for processing Actor events, and starts an interval for regularly sending PERSIST_STATE events, so that the Actor can regularly persist its state in response to these events.

    This method should be called immediately before performing any additional Actor actions, and it should be called only once.

    Returns None

is_at_home

  • is_at_home(): bool

  • Return True when the Actor is running on the Apify platform, and False otherwise (e.g. local run).

    Returns bool

log

  • log(): logging.Logger

  • The logging.Logger instance the Actor uses.

    Returns logging.Logger

metamorph

  • async metamorph(target_actor_id, run_input, *, target_actor_build, content_type, custom_after_sleep): None

  • Transform this Actor run to an Actor run of a different Actor.

    The platform stops the current Actor container and starts a new container with the new Actor instead. All the default storages are preserved, and the new input is stored under the INPUT-METAMORPH-1 key in the same default key-value store.

    Parameters

    • target_actor_id: str

      ID of the target Actor that the run should be transformed into

    • run_input: Any = None

      The input to pass to the new run.

    • keyword-onlytarget_actor_build: str | None = None

      The build of the target Actor. It can be either a build tag or build number. By default, the run uses the build specified in the default run configuration for the target Actor (typically the latest build).

      The content type of the input.

    • keyword-onlycustom_after_sleep: timedelta | None = None

      How long to sleep for after the metamorph, to wait for the container to be stopped.

    Returns None

new_client

  • new_client(*, token, api_url, max_retries, min_delay_between_retries, timeout): ApifyClientAsync

  • Return a new instance of the Apify API client.

    The ApifyClientAsync class is provided by the apify-client package, and it is automatically configured using the APIFY_API_BASE_URL and APIFY_TOKEN environment variables.

    You can override the token via the available options. That's useful if you want to use the client as a different Apify user than the SDK internals are using.

    Parameters

    • keyword-onlytoken: str | None = None

      The Apify API token.

    • keyword-onlyapi_url: str | None = None

      The URL of the Apify API server to which to connect to. Defaults to https://api.apify.com.

    • keyword-onlymax_retries: int | None = None

      How many times to retry a failed request at most.

    • keyword-onlymin_delay_between_retries: timedelta | None = None

      How long will the client wait between retrying requests (increases exponentially from this value).

    • keyword-onlytimeout: timedelta | None = None

      The socket timeout of the HTTP requests sent to the Apify API.

    Returns ApifyClientAsync

off

  • off(event_name, listener): None

  • Remove a listener, or all listeners, from an Actor event.

    Parameters

    • event_name: Event

      The Actor event for which to remove listeners.

    • listener: Callable | None = None

      The listener which is supposed to be removed. If not passed, all listeners of this event are removed.

    Returns None

on

  • on(event_name, listener): Callable

  • Add an event listener to the Actor's event manager.

    The following events can be emitted:

    • Event.SYSTEM_INFO: Emitted every minute; the event data contains information about the Actor's resource usage.
    • Event.MIGRATING: Emitted when the Actor on the Apify platform is about to be migrated to another worker server. Use this event to persist the Actor's state and gracefully stop in-progress tasks, preventing disruption.
    • Event.PERSIST_STATE: Emitted regularly (default: 60 seconds) to notify the Actor to persist its state, preventing work repetition after a restart. This event is emitted together with the MIGRATING event, where the isMigrating flag in the event data is True; otherwise, the flag is False. This event is for convenience; the same effect can be achieved by setting an interval and listening for the MIGRATING event.
    • Event.ABORTING: Emitted when a user aborts an Actor run on the Apify platform, allowing the Actor time to clean up its state if the abort is graceful.

    Parameters

    • event_name: Event

      The Actor event to listen for.

    • listener: Callable

      The function to be called when the event is emitted (can be async).

    Returns Callable

open_dataset
