To request the FB app events API, I would need to use an app access token.
It says in the doc "The Facebook SDK automatically logs app installs, app sessions, and in-app purchases."
And "Do not store your app access token on the client" also "Again, for security, app access token should never be hard-coded into client-side code, doing so would give everyone who loaded your webpage or decompiled your app full access to your app secret, and therefore the ability to modify your app. This implies that most of the time, you will be using app access tokens only in server to server calls."
Then how can I make a request from the app SDK if I am not storing/hard coding the app access token in the mobile app code?
