have you injected your app with ngRoute?
if not have a look at this example
$resource[
^] there is a complete example at the bottom of the page.
Edit: Added this to explain comments from user
var app = angular.module('AppName',[]);
app.controller("ControllerName", function($scope, $http) {
$scope.CallAPI = function() {
var request = $http({
method: "post",
url: '/WebApiControllerName/TaxesSLiced',
data: { entity: TaxSliced }
});
request.success(function(data) {
});
request.error(function(error, status) {
});
};
});
