Hi,

Not sure if this is the right forum for this type of question.  We're trying to setup a new Commerce Cloud site with some customizable SKU's that would trigger configuration in CPQ.  We are able to trigger the CPQ configuration in the preview site and completed the configuration in CPQ successfully with an item added to the shopping cart.  The price configured in CPQ is $100, however, the price captured in the cart is zero.  In addition, the Web API configured for "External Price Validation" (Preview) was not called.  Is there additional settings required to capture the external price returned
