django-rest-framework causes RawPostDataException:

I have this code that works fine with my ajax request:

    // client
    $.ajax({
        type: "POST",
        url: "api",
        contentType: "application/json; charset=utf-8",
        headers: {'X-CSRFToken': '{{ csrf_token }}'},
        data: JSON.stringify({
            x: $("#x").val(),
        }),
        success: response,
        dataType: 'json',
        minLength: 0,
    });

# server - views.py:
@staff_member_required
def api(request):
    params = request.POST

but in addition to the ajax approach, I want a secondary approach to allow people use token authentication so I modified the view.py as below:

# server - views.py:
@api_view(['GET', 'POST'])
@authentication_classes((TokenAuthentication, SessionAuthentication, BasicAuthentication))
@permission_classes((IsAuthenticated,))
@staff_member_required
def api(request):
    params = request.POST

and the token authentication client code:

headers = {'Authorization': 'Token {}'.format(mytoken), 'Content-Type': 'application/json'}
response = requests.post(BASE_URL, headers=headers, json=data)

As soon as I add @api_view, my ajax request causes a server error:

ERROR: Internal Server Error: /api

Apparently once you use django-rest-framework, you'll have to use
