AWS Query Signer

AWSQS Service Status:

• 2009.09.14: GAE downtime schedule for the remainder of 2009 announced. See the notice on the SowaCS Google Group for more information.
• 2009.09.12: Passed 1M requests served since inception. That's about a 1% load over the last three months, or about a 3% average current load, based on the GAE free quotas.
• 2009.08.27: GAE downtime on 2009.09.02, 00:00 UTC, for one hour. See the notice on the SowaCS Google Group for more information.
• 2009.08.21: Fixed key lookup issue for case where an AWSId use is attempted before it was registered; the 'miss' was not being cleared from cache when the AWSId was later registered, and so was blocking any use of that key.
• 2009.08.21: You can now use SSL (HTTPS) for your requests. See Tips for more information.

What:

The AWS Query Signer (AWSQS) service is a prototype REST request signing service intended for use with the Amazon Web Services / Product Advertising API (AWS/PAA).

Using AWSQS can be as simple as this: sample AWSQS signed request.

Why:

Beginning August 15, 2009, AWS/PAA requests are required to be authenticated. AWSQS aims to provide for this requirement as transparently as possible for current applications using AWS/PAA.

Transparent: Using AWSQS, your transition could be as simple as as inserting "sowacs.appsot.com/AWS/" into your current AWS/PAA requests. See the section on redirect usage for more information.

REST: An AWSQS REST API has been provided for those of you looking for something to support more complex custom programming.

DIY: The downloads section can assist the DIYers among you. The sample code does not use the AWSQS service; it is intended for those embarking on independent projects. Also be sure to visit the AWS/PAA forums and resources pages (see AWSQS Resources for links).
