I am searching for the same thing. I found an example how to implement a google SOAP client in the "learning ez publish 3" book. I havent tried it yet.
Is there someone who could tell me if there exists an extension which I can use?
I've created an extension to manage several external apis: google, amazon and some weather thing.
I've used a different soap client than the one from ez (nusoap) and it works fine.
I would have to clean it a wee bit to be able to put it in the contributions and as I'm on holidays two weeks starting on saturday (can't wait), that's unlikely I will care about it for a long while.
