I'm developing a Magento client (built in Java) that's supposed to generate orders through REST API.
I couldn't find anything related to generate orders over REST, found only over SOAP.
Is it already supported at Magento 1.7? If don't, is there any extension that does it?
Magento have introduced REST API in their Community Edition 1.7 as stated here
Also check this to see how it works
