OK, i'm figuring out by myself using reverse engineering. I think the API feature for getting posts and posting into newsfeed is important, but nobody will help me with this.

This can stay together with his circle of relatives. But here, frankly, it is still a rip-off.  Take the example of other CMS to post related to waterproof hiking boots. The capacity to trade the shape of the URL is built, and rightly so.
