I take a look on Angular API for $resource and I didn\'t find some way to send a Request Body to a RESTful service.
Request Body
I know this is possible using $http
As long as the action supports a body message (e.g. POST, but not GET), you can pass a data parameter to the action method of your resource, which will be sent in the body of the request:
yourResource.save(yourData)
