When using the Get/List products endpoints the model clearly shows that productCategories should be returned in the response. However this does not seem to be the case. Our store has not used product categories until the 2 I just created and assigned 1 of them to a product. The Product Categories "Count" inside the shipstation admin shows 1 product belonging to my new category (which is correct) however when attempting to retrieve this information via the Get/List products endpoints "productCategory" field is always returned as NULL. Is there something I am doing wrong or is it actually not possible to get product categories via the API ?
