Facebook has recently announced the release of Graph API (v4.0) and Marketing API (v4.0). The changes to these APIs are highlighted by updates to webhooks, Business Asset Groups, and ad creation and editing. Ad Insights also gains new functionality that provides more granular insight into traffic.

It is easy enough to conclude that beneath the layers of the mobile application, there are indeed API calls but just that the API is private and not yet made available. If you are itching to discover the APIs but did not know how to, help could be on the way.
