If the payment is completed, you should call ``order.mark_paid(provider, info)``
with ``provider`` being your :py:attr:`identifier` and ``info`` being any string
you might want to store for later usage. Please note, that if you want to store
something inside ``order.payment_info``, please do a ``order = order.clone()`` before
modifying or saving the order object.
something inside ``order.payment_info``, please do it after the ``mark_paid`` call,
as this call does a object clone for you. Please also note that ``mark_paid`` might
raise a ``Quota.QuotaExceededException`` if (and only if) the payment term of this
order is over and some of the items are sold out. You should use the exception message
to display a meaningful error to the user.
The default implementation just returns ``None`` and therefore leaves the
order unpaid. The user will be redirected to the order's detail page by default.
