When we create a Sales Order in iVend and create a delivery against a Sales order in iVend system will award loyalty points to a customer and same loyalty points will be integrate to Magento.
Whereas when a Sales order is created in Magento and it integrates to iVend. Against the sales order created from magento a delivery is created in iVend then loyalty points are not awarded to the customer.
Issue have fixed in latest Magento connector.
