Yes, there are indeed ways of find out why an API call will fail. I'll explain how.
All API methods are designed to be used in a way where you never have to check for success of not. Not returning a status code is our way of saying that the API will always "just work" and that you should not litter your code with checks for success.
If logging doesn't reveal the issue then I'd be happy to take a look at your code and help spot the problem.
