slack_bolt.kwargs_injection.args API documentation

class Args:
    """All the arguments in this class are available in any middleware / listeners.
    You can inject the named variables in the argument list in arbitrary order.

        @app.action("link_button")
        def handle_buttons(ack, respond, logger, context, body, client):
            logger.info(f"request body: {body}")
            ack()
            if context.channel_id is not None:

                trigger_id=body["trigger_id"],
                view={ ... }
            )

    Alternatively, you can include a parameter named `args` and it will be injected with an instance of this class.
