Why is ItemLookup not returning any price information even when requesting all 3 offer groups?

Question

I am using the Product Advertising API to do an ItemLookup on a valid ASIN, requesting all three flavors of offer groups, and I am not getting back any price information. Yet w

Answer 1

Edit:

An item returned by the Amazon Product API can represent either a single variation item (a single size and/or a single color) or a variation parent. When a single variation item is returned, you just have to use the same approach as you initially did and you'll be able to fetch the price.

A parent variation item (your case), however, is not associated with any offer (price), because it is an abstraction of a product and acts as a container for the existing product variations (different sizes, colors).

In this case, every variation contained within the variation parent has its own price and you can simply iterate through the set of variations and fetch the price you need.

Adding the Variations response group to your search/look up request is crucial, so don't omit it.

The request body:

   
   
       
           xxxxxxxxxxxxxxxxxxx
           xxxxxxxx
           
               ASIN
               All
               B008M4TB9C
               Variations
           
           xxxxxxxx
           2012-12-13T23:49:27Z
       
   

The response body.

A price for a single variation can be found under:

Item->Variations->Item->Offer->OfferListing->Price.
