We aren't accepting NPS response with more than 65536 characters

Make a purchase with more than 223 items using the NPS connector. The gateway does not support orderList so long and shows this message:

Message: Unknown Error on AutoSettleThe maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

There is no workaround.
