This container will consist of one or more Product Identifier types that are supported, or possibly required to be used when listing a product. These Product Identifier types will be common Global Trade Item Number (GTIN) types such as UPC, ISBN, and EAN. Each Product Identifier type that is applicable to the category will be returned in a separate NameRecommendation container. To see if one or more of the Product Identifier types are actually required at listing time, the seller will need to look at the ValidationRules container and the MinRequired value. If two Product Identifier types are returned, and the MinRequired value is the
2, the seller will be required to use both Product Identifier types at listing time. If the MinRequired value was
0, one or both of those Product Identifier types could be used, but they would not be required.
Note: This container is for future use, and is not currently returned in the GetCategorySpecifics call. Until the ProductIdentifiers container is wired on and returned, an alternative way to see if a Product Identifier type is required for a category is to identify the Product Identifier type through the Recommendations.NameRecommendation.Name field in the GetCategorySpecifics response, and then look at the corresponding Recommendations.NameRecommendation.ValidationRules.MinValues field. The GetCategoryFeatures call can also be used, and the seller will look for the values returned for that category under the EANEnabled, ISBNEnabled, UPCEnabled, and EANEnabled, ISBNEnabled, BrandMPNIdentifierEnabled fields that indicate the Product Identifier types that are supported/required for the category.
