API Scratchpad for Amazon

For Amazon Product Advertising API: https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html Amazon has an official API scratchpad: http://associates-amazon.s3.amazonaws.com/scratchpad/index.html I don't like the official scratchpad because: - It is browser based, it's not an app. - It cannot save my credentials - It cannot save the data I entered - it's kind of complicated So I build this app. The app has the following features: - It can save your credentials, you don't need to enter them again and again - It can also save the data you entered. Restart this app or even restart your computer, you lose nothing. - It formats the result XML in a easy to read style - It's very intuitive, very easy to use - Regions supported: CA, CN, DE, ES, FR, IN, IT, JP, UK, and US - Operations supported: - BrowseNodeLookup - CartAdd - CartClear - CartCreate - CartGet - CartModify - ItemLookup - ItemSearch - SimilarityLookup
