Laravel how to response only 204 code status with no body message

You may return null:

return response(null, 204);

Edit: I didn't read the question before answering and I notice now that you are already doing this. I recommend you just do an empty / null check on the body in your Ruby code if possible.

Try return Response::make("", 204);

Update: Mark's answer is more up to date:

return response()->noContent()

You can also do return response()->noContent();
