Selecting Categories using API in Amazon MWS

Question

I am developing a integration between a desktop application and Amazon MWS and need to be able to offer users a choice of categories to put the product they are listing into. My problem is that I can't find any way of programmatically getting the current categories from MWS using the API.

Additionally once I have a category reference to use I will need a way to the pull in and add the category specific XML child of ProductData (eg Home, Jewelry, Computers, etc) but they don't seem to be linked in any well defined way. For example, I can't say "if the chosen category is reference nnnnn ask them to populate the Computers specific ProductData", unless I write something myself to map them.

Has anyone else come across these problems and found a workable solution?

Any help appreciated...

I am currently exploring the option of limiting users to only selling products already listed on Amazon but still can't figure out how to pull in the correct category specific XML. There are various product look-ups but they all seem to work from either my SKU (which will not yet be there) or Amazons ASIN (which I don't yet know)

You can use amazon advertizement api for this.

You have to create account on amazon affiliate programme.From that you have to get security credentials also .

After That go to BrowseNode Tree Page and download root categories list and save it to file or database.From there you get categoryname and their browseNodeId.

Then call BrowseNodeApi to get Child Categories for parent Category.

Please Follow This Link http://docs.aws.amazon.com/AWSECommerceService/latest/DG/ProgrammingGuide.html

code for calling BrowseNodeApi SignedRequestHelper helper = new SignedRequestHelper(appConfig["AWSAccessKey"], appConfig["AWSSecretKey"], appConfig["endpoint"]);

    string url = helper.Sign("http://ecs.amazonaws.com/onca/xml?Service=AWSECommerceService&Operation=BrowseNodeLookup&BrowseNodeId=" + value + "&AssociateTag=beginners00-00&Version=2011-08-01");
    HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;

    // Get response  
    using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
    {
    }

and also download SignatureGenerator class HMAC
