The import/export format for shipping promotions is similar to that of order promotions. The major difference is that shipping promotions let you define discounted shipping methods.
This sample XML shows a tiered shipping promotion granting a 50% or 100% discount on selected shipping methods provided the qualifying products total exceeds $50 or $100 respectively.
<promotion promotion-id="tiered-shipping-promo" campaign-id="c1">
<enabled-flag>true</enabled-flag>
<name xml:lang="x-default">Tiered ShippingPromotion</name>
<shipping-promotion-rule>
<shipping-methods>
<method-id>ups-ground</method-id>
<method-id>ups-air</method-id>
</shipping-methods>
<discounts condition-type="shipment-total">
<discount>
<threshold>50</threshold>
<percentage>50</percentage>
</discount>
<discount>
<threshold>100</threshold>
<fixed-price>0</fixed-price>
</discount>
</discounts>
</shipping-promotion-rule>
</promotion>The promotion in the above example has a
condition-type of "shipment-total". Alternatively a shipping promotion might
specify a condition-type of "product-quantity". Such promotions require
that a certain quantity of qualifying products be in the shipment in order
for the discount to apply. The XML for this type of promotion will include
a <qualifying-products> section before the
<discounted-methods>.
In general, a shipping promotion with a condition-type of "product-quantity" requires that a specified number of qualifying products and no excluded products be in the shipment. However, whether or not a shipping promotions permits or prohibits excluded products is configurable. The optional element <prohibit-excluded-products> which accepts values of true or false can be included in the promotion XML to control this behavior. If the element is omitted for a newly imported promotion, excluded products are prohibited.
See the schema promotion.xsd for details.
