Hello !
I develop a RESTful webapp with AngularJS, I use the ngResource
module to send http requests. The webservice is developped with FuelPHP.

I believe this is an issue with how PHP is handling the POST. When using AngularJS $resource it will POST the object with JSON as the post's BODY. PHP does not see this as a regular parameter. I've had to do this in other PHP (never used Fuel)
$requestBody = file_get_contents('php://input');
$requestBody = json_decode($requestBody, true);
Then you should be able to inspect $requestBody as a normal json object.
