At a first glance you might think that offering an API method that returns information about your application users might not be a good idea. With the increasing usage of APIs for business related purposes you might fear that you’re giving away precious information about your customers.
But think again. If you give the right amount of information, applications built on top of your API will be able to offer a better service to your users. Your final user will have a better experience and that might turn out to generate more business for you.
