Facebook does not really allow you to specify that one post should only be sent to a specific group of people (like this should only be visible to my family, this should only be visible by close friends), the functionality is hidden, it's not end-to-end encrypted, and it expects you to specify manually the list of recipient each time if it's something other than just "all friends".

Facebook also shows you everything in a feed (with algorithmic ordering to make everything worse), instead of sending you to the user's feed so that you can have all the context.

Dependong on your API there may be headers that can help you.
