Introducing my Amazon Web Service: Find Your Profile, View Your Wishlist or Reviews

September 15th, 2009

My online portfolio is increasingly scattered through the internet (reviews and wishlist are on Amazon, source code on github / Google Projects, resume on LinkedIn, and so on). I’ve been working on a couple services that will eventually pull my portfolio together while keeping a single point of reference, and… I’m sharing these services.

Introducing my Amazon Web Service.

How it works.

Basically if you have a Wishlist or a Review list on Amazon you can:

Discover your profile – retrieve your ListId (for WishLists) or CustomerId (for Reviews):

Discovery URI:

http://adam.kahtava.com/services/amazon/discover/user/{user-name}.{xml|json}

Example:

Request: http://adam.kahtava.com/services/amazon/discover/user/adam-kahtava.xml

Response:

<Profile xmlns="http://adam.kahtava.com/services/amazon" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
  <CustomerId>A2JM0EQJELFL69</CustomerId>
  <ListId>3JU6ASKNUS7B8</ListId>
</Profile>

View your Reviews - retrieve your Reviews by username or Amazon CustomerId.

By customerId URI:

http://adam.kahtava.com/services/amazon/reviews/id/{customerId}.{xml|json}

By username URI:

http://adam.kahtava.com/services/amazon/reviews/user/{user-name}.{xml|json}

Example:

Request: http://adam.kahtava.com/services/amazon/reviews/id/A2JM0EQJELFL69.xml

Response:

<Reviews xmlns="http://adam.kahtava.com/services/amazon" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
  <Review>
    <ASIN>0321125215</ASIN>
    <Authors>Eric Evans</Authors>
    <AuthorsMLA>Evans Eric.</AuthorsMLA>
    <Content>Through this book Evan's ...

View your Wishlist - view your Wishlist by username or Amazon ListId.

By listId URI:

http://adam.kahtava.com/services/amazon/wishlist/id/{listId}.{xml|json}

By username URI:

http://adam.kahtava.com/services/amazon/wishlist/user/{user-name}.{xml|json}

Example:

Request: http://adam.kahtava.com/services/amazon/wishlist/user/adam-kahtava.json

Response:

[{"ASIN":"0471467413","Authors":"Mostafa Abd-El-Barr, Hesham El-Rewini", ...

So now what?

Head on over to my Reviews and Reading List pages. These pages make use of the data from this service. I should also mention that, this service was built on a previous iteration of my Amazon Web Service (How To Display Your Amazon Reviews and Wish List Using Amazon’s Web Services).

How To Display Your Amazon Reviews and Wish List (on your site) Using Amazon’s Web Services

October 6th, 2008

If you’ve ever landed on Amazon then you’re probably familiar with their reviews and wish lists. Amazon provides access to these items (and many-many more) through their extensive web services – the Amazon web services can be complex and overwhelming when all you want is a review list and a single user specific wish list. For this site I wanted to pull in my reviews and wish list – displaying them alongside my blog. It’s fair to note, that user reviews are available via an RSS feed (but this feed doesn’t include all the details I wanted) and the wish list page still doesn’t provide an RSS feed. So a custom Amazon web service request was in order.

Let me try to make this story short.

If you want to request your reviews and your wish list you need the following:

Once you have a wish list or review, you then need to:

Once you’ve collected all those bits, you need to:

  • Checkout and download the source code for the project and build the assembly or download the pre-compiled assembly.
  • Add the assembly reference to your project (remember, I’m assuming you’re using .NET).
  • Make a call to the application which will generate XML files containing your respective reviews and wish list.

Setting up the call would look something like this:

IAmazonRequest amazonRequest = new AmazonRequest() {
 AssociateTag = "adamkahtavaap-20",
  AWSAccessKeyId = "1MRF________MR2",
  CustomerId = "A2JM0EQJELFL69",
  ListId = "3JU6ASKNUS7B8"
};

IFileParameters fileParameters = new FileParameters() {
  ProductFileNameAndPath = @"Products.xml",
  ReviewFileNameAndPath = @"Reviews.xml",
  ErrorFileNameAndPath = @"Errors.xml"
 };

IAmazonApplication amazonApplication = new AmazonApplication(amazonRequest, fileParameters);

amazonApplication.Save();

And Viola!

If you’d like to provide some design guidance, fix a bug, or request a feature, then visit (or join) the project on Google Code.

The Amazon E-Commerce Service (ECS) Web Services Description Language (WSDL) and ASP.NET

July 3rd, 2006

While developing a component for Amazon’s E-Commerce Service (ECS) Web Services Description Language (WSDL) (Version 4.0), I encountered a couple minor issues and found the following links of use:

Issues:

Version 4.0 of the ECS WSDL is not compatible with Microsoft’s Visual Studio (VS) 2003. However, the ECS WSDL works fine in VS 2005, a workaround for VS 2003 and other known issues can be found on the Amazon.com Associates: XML Developers Discussion Board.

Useful links:

This website pulls my reviews, and my recommended reading list off of Amazon.
The originating Amazon data can be viewed here: my Amazon reviews, my Amazon wish list.
