Why can't I get posts from a group via facebook api?

Question

Facebook

Good day.
I make a request to facebook api via /group_number/posts/ and fb returns only half of the posts (there is no filter: i.e. not by date, not by author)
Is there some kind of limit or something else related
PS also noticed which can return old posts that no longer exist

Answer 1

1 I didn’t receive posts on fb via api, but YouTube also has caching, so I’m imitating a browser. curl when requested.
2 Perhaps your script is caching, the request is not updated.

Answer 2

Use feed, posts should close.

You must be an admin in the group.
