Alternatively, you may download the ZIP file, extract the contents to a folder and open index.html in a browser. This tool works best with Mozilla Firefox; other browsers including Internet Explorer have not been tested.
This tool allows you to provide a Product Advertising API request URL, your AWS Access Key ID and your AWS Secret Key. It then displays the corresponding signed URL. It also shows the intermediate values in the computation. You can compare these with the values you are seeing in your application, which should make it easier to debug problems.
We will be grateful for feedback to improve this tool. Please post feedback at the Product Advertising API Community Forum.
Please note that this tool only works with REST/Query requests and not with SOAP.
