Using Amazon's affiliate API for autocompletion with SearchIndex (Category)

Question

I need to have Amazon affiliate API for autocompletion work with SearchIndex (Marketplace category)

For example, I have a site that searches for Kindle Books, and would like to have Amazon's autocompletion only return Kindle Book results.

The following URL will return all products with the keyword 'photography'

http://completion.amazon.com/search/complete?search-alias=aps&client=amazon-search-ui&mkt=1&q=photography

How can I have the above URL return only Kindle Books with keyword 'photography'?

Answer 1

I have found the solution.

The search-alias query needs to be changed to digital-text, like so:

http://completion.amazon.com/search/complete?search-alias=digital-text&client=amazon-search-ui&mkt=1&q=photography

You can do this for any marketplace category by changing search-alias to the appropriate query variable.
