The sizing keys used in the Salesforce B2B Commerce Global APIs five distinct operations.

The sizing keys used in the Salesforce B2B Commerce Global APIs perform five distinct operations. Three of these operations are:

Refetch data (used on some Logic classes): This operation indicates that the data should be refetched from the database instead of using the cached data. For example, ccrz.ccServiceCart.getCart(ccrz.ccAPI.SZ_REFETCH) will refetch the cart data and refresh the cache.

Related Query to call (sub queries or direct queries): This operation indicates that the related entities should be retrieved by using sub queries or direct queries. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_SUBQUERY) will use sub queries to fetch the related entities for each product, while ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_DIRECTQUERY) will use direct queries to fetch the related entities separately.

Object type casting: This operation indicates that the data should be cast to a specific object type. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_SOBJECT) will cast the data to sObjects instead of transformed objects.
