Amazon PA API5 Updates

Earlier this week, I noticed I had access to the Amazon PA API, so I decided to take the opportunity to convert my old PA API 4 tools, to the latest release (PA API 5). Efficiency guidelines, periodically disabling the resource, so this was my first opportunity to work with the new API.

I am not sure why, I thought the new release of the API would be easier to use, as related to development efforts for Amazon Product Search tools. In my opinion, the earlier release, PA API 4 was easier, especially the signing process.

That said, after some research and testing, I was able to get three program versions working using different frameworks:

  • Java Servlet not using the Amazon supplied SDK
  • Java Servlet using the SDK
  • PHP Version

When I install the new tools on WiredPages, I will be using the Java Servlet version which does not incorporate the Amazon supplied SDK. The following graphics illustrate how the new tools will look on the site, however [shown below] running in local mode from my IDE (NetBeans).

If you are familiar with my earlier Amazon Product Search tools, you will note the new tools are similar to the old. Updates also included new search categories. I will probably release the new tools sooner rather than later, however I am still researching security issues. Think I have found most of the program bugs.
