My Amazon Wishlist widget, AmzWish, displays your Amazon wishlist (or wedding/baby registry). Visitors can click on items from your wishlist and purchase them for you, and Amazon will ship them directly to you. You can see AmzWish in action in the left-hand column of this blog, as well as in the right-hand column at the AmzWish home at textbox1.com.
In order to use this widget you'll first want to determine the list id of the list you want to use and then generate the code to paste into your web page. To do so, visit the AmzWish home page.
If you're a geek, here are some of the geeky details about how I built AmzWish. It took about 20 minutes, thanks to RSSBus. AmzWish makes use of RSSBus' implementation of Amazon E-Commerce Services (ECS).
Mainly it uses the RSSBus AmazonOp called amazonListGet to retrieve a particular listid and display items from that list. When someone then clicks on one of those items, it uses another RSSBus operation called amazonCartCreate to create a new cart on Amazon and direct the user to the purchase page for that cart. The user can then purchase the item and have it shipped to you. If you want to try it out for yourself, you can download the source templates here.
