Download
This helper is available online at http://associates-amazon.s3.amazonaws.com/signed-requests/helper/index.html

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.

This tool does not transmit any data; all calculations are done using JavaScript in your browser, hence you AWS Access Key and Secret Key are safe. Please be aware that Amazon.com will never ask you for your AWS Secret Key. This tool is provided only to help you debug your application by comparing the values shown by the tool with the values calculated by your application. Since this comparison can be accomplished by using a fake secret key instead of your actual one, you are strongly encouraged to do that to further reduce the chances of exposing your AWS Secret Key.

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.

Classic ASP Example
I am a Classic ASP developer. I want to integrate Amazon Custom Book search to my site http://www.FAT.lk Does anyone know how to create the API URL using Classic ASP / VBScript (i.e. without using Javascript)

BUG: if you omit AWSAccessKeyId
If you use the signed requests helper and omit the AWSAccessKeyId as a param in your initial URL, it will add it (which makes sense, since we provide it up top) but it adds it at the wrong position. In my test, it adds it *after* the timestamp, which is incorrect according to this doc: http://docs.amazonwebservices.com/AWSECommerceService/latest/DG/index.html?RequestAuthenticationArticle.html= As a result, it then creates an invalid signature for the request.

Could use a validator
A simple signed URL validator would be more useful to most developers using prepared functions for signing. Paste in a signed URL and get an OK or an error report.
