class SetBotPrecheckoutResults(TLObject):  # type: ignore
    """Once the user has confirmed their payment and shipping details, the bot receives an `updateBotPrecheckoutQuery <https://core.telegram.org/constructor/updateBotPrecheckoutQuery>`_ update.
    Use this method to respond to such pre-checkout queries.
     **Note**: Telegram must receive an answer within 10 seconds after the pre-checkout query was sent.

    .. include:: /_includes/usable-by/bots.rst

    Details:
        - Layer: ``229``
        - ID: ``9C2DD95``

    Parameters:
        query_id (``int`` ``64-bit``):
            Unique identifier for the query to be answered

        success (``bool``, *optional*):
            Set this flag if everything is alright (goods are available, etc.) and the bot is ready to proceed with the order, otherwise do not set it, and set the ``error`` field, instead

        error (``str``, *optional*):
            Required if the ``success`` isn't set. Error message in human readable form that explains the reason for failure to proceed with the checkout (e.g. "Sorry, somebody just bought the last of our amazing black T-shirts while you were busy filling out your payment details. Please choose a different color or garment!"). Telegram will display this message to the user.

    Returns:
        ``bool``
