The following error (A connectivity issue was encountered when trying to connect to parcelforce: The remote server returned an unexpected response: (413) Request Entity Too Large.) from Parcelforce is caused when there is too many items on the order. Parcelforce allows a certain number of items when creating a shipment through API (Mintsoft). The maximum number of items allowed to be shipped with Parcelforce through Mintsoft is 800, any more than this can cause the system to time out and produce an error.
