angularjs 1.5 / laravel bad request 400

Question

When I do a POST request using my angular app to my laravel api I get an error bad request 400 , however GET requests work normally, also I do POST requests using POSTMAN and it works , here is my code :

$http.get('http://localhost/laravel/datingApp/jobapi/public/api/user/users');

this get request works, this post request doesn't (data is an js object {'email': 'value','password': 'value'}) :

  $http({

            url: 'http://localhost/laravel/datingApp/jobapi/public/api/user/login',
            method: 'POST',
            contentType: "application/json",
            data: data

  }).success(function(data) {

            console.log(data);

  });

also I tried doing that just regular way: $http.post('blabla'); but it doesn't work either :(

edit: sorry didn't include error:

That was a stupid error, but thanks to @piscator I have found it, Laravel by default returns 400 when validation rules are not met , So my input was wrong all the time that is the reason I got 400.
