Anyone linked to Amazon MWS

I am working on a project that needs to talk to the Amazon (ideally UK) MWS service to be able to collect order information etc. Has anyone developed classes or another way to connect with it?

what is Amazon MWS?

It is a way to link with Amazon Marketplace (if you are a seller) to be able to find things out about the buyer, orders etc.

Sorry. I know more about S3/Glacier/EBS than MWS.
