In Chapter 17 of Pro Web 2.0 Mashups, I created a mashup of an Amazon Wishlist and Google Spreadsheets. When I returned to examine my code last night, I learned that it no longer worked.  Why?  First, the  Amazon Ecommerce API morphed into the Amazon Product Advertising API; I was puzzled why the API wasn't listed where I expected it to be.  Unfortunately, Amazon, in its infinite and inscrutable wisdom,  also decided to kill the ListLookup operation, the one call that I depended on to retrieve the content of my Amazon wishlist.  (I'm not alone in having broken applications because of this change.)
So what to do now? Â Interestingly enough, someone just announced a JSON feed service for a given wishlist, for example, Jeff Bezos' wishlist and mine (in JSON). Â I hope it stays around. Â How does it work given the demise of the ListLookup operation? Â My guess is that some sort of screen-scraping is going on.
