Amazon Reports API gives both child and parent ASINs. Is there any field by which i can identify both separately?

Question

I am using a couple of Reports via Amazon MWS API. Specifically the _GET_MERCHANT_LISTINGS_DATA_ and _GET_AFN_INVENTORY_DATA_. Both these reports gives the list of all products, both parent ASIN & child ASIN. I don't have the need for parent ASIN. And i don't see any field by which i can identify whether the item is a parent or a child. I have to manually open each ASIN's product page and then verify whether its a parent or child product.

Is there any field or any other API which will provide the list of items filtered with parent/child?

Answer 1

Parent and child variation information can found in the "getMatchingProduct" call/response of the mws::products API.

Contains product variation information, if applicable. If your search criteria match a product that is identified by a variation parent ASIN, the related VariationChild elements are contained in the Relationships element. If your search criteria match a specific variation child ASIN, the related VariationParent element is contained in the Relationships element. Note: Because this operation does not return all product attributes, it is possible to get VariationChild elements with different ASIN values but the same variation element values. These are distinct variation child ASINs even though product attributes that differentiate them from each other are not returned.

Variation attributes can be found in the VariationChild element of default.xsd. Note: Variation attributes are not included in the VariationChild element if the input ASIN values have more than 2000 combined VariationChild elements.
