Customer Reviews can be retrieved through the Amazon Product Advertising API, they are not available in MWS.
The ItemLookup and ItemSearch calls both have a parameter ResponseGroup
which you can set to Reviews
. The response will contain an IFrameURL
that links to a HTML representation of all reviews of a product. Unfortunately there seems to be no way to actually pull the raw data - you'll have to parse the HTML if that is what you want to do.
This is an example of such a response (as shown here)
