This requires a client ID and client secret from Slack. You should either pass them to this constructor, or make sure that your Flask application config defines them, using the variables :envvar:`SLACK_OAUTH_CLIENT_ID` and :envvar:`SLACK_OAUTH_CLIENT_SECRET`. Args: client_id (str): The client ID for your application on Slack. client_secret (str): The client secret for your application on Slack scope (str, optional): comma-separated list of scopes for the OAuth token redirect_url (str): the URL to redirect to after the authentication dance is complete redirect_to (str): if ``redirect_url`` is not defined, the name of the view to redirect to after the authentication dance is complete. The actual URL will be determined by :func:`flask.url_for` login_url (str, optional): the URL path for the ``login`` view. Defaults to ``/slack`` authorized_url (str, optional): the URL path for the ``authorized`` view. Defaults to ``/slack/authorized``. session_class (class, optional): The class to use for creating a Requests session. Defaults to :class:`~flask_dance.consumer.requests.OAuth2Session`. storage: A token storage class, or an instance of a token storage class, to use for this blueprint. Defaults to :class:``. subdomain (str, optional): the name of the subdomain under which your Slack space is accessed. Providing this may improve the login experience. rule_kwargs (dict, optional): Additional arguments that should be passed when adding the login and authorized routes. Defaults to ``None``. :rtype: :class:`~flask_dance.consumer.OAuth2ConsumerBlueprint` :returns: A :doc:`blueprint <flask:blueprints>` to attach to your Flask app. """ scope = scope or ["identify", "chat:write:bot"] slack_bp = SlackBlueprint( "slack", __name__, client_id=client_id, client_secret=client_secret, scope=scope, base_url="", authorization_url="" if subdomain is None else f"https://{subdomain}", token_url="", redirect_url=redirect_url, redirect_to=redirect_to, login_url=login_url, authorized_url=authorized_url, session_class=session_class, storage=storage, rule_kwargs=rule_kwargs, ) slack_bp.from_config["client_id"] = "SLACK_OAUTH_CLIENT_ID" slack_bp.from_config["client_secret"] = "SLACK_OAUTH_CLIENT_SECRET" @slack_bp.before_app_request def set_applocal_session(): g.flask_dance_slack = slack_bp.session return slack_bp
