    Make a blueprint for authenticating with Atlassian using OAuth 2. This requires
    a client ID and client secret from Atlassian. You should either pass them to
    this constructor, or make sure that your Flask application config defines
    them, using the variables :envvar:`ATLASSIAN_OAUTH_CLIENT_ID` and
    :envvar:`ATLASSIAN_OAUTH_CLIENT_SECRET`.

    Args:
        client_id (str): The client ID for your application on Atlassian.
        client_secret (str): The client secret for your application on Atlassian.
        scope (str, optional): comma-separated list of scopes for the OAuth token.
        reprompt_consent (bool): If True, force Atlassian to re-prompt the user
            for their consent, even if the user has already given their
            consent. Defaults to False.
        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 ``/atlassian``.
        authorized_url (str, optional): the URL path for the ``authorized`` view.
            Defaults to ``/atlassian/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:`~flask_dance.consumer.storage.session.SessionStorage`.

    :rtype: :class:`~flask_dance.consumer.OAuth2ConsumerBlueprint`
    :returns: A :doc:`blueprint <flask:blueprints>` to attach to your Flask app.
