[Facebook][Graph-API] Facebook doesn't return all posts for a page – Facebook api

I’m currently testing to get some posts from a media page for a specific time range:

But surprisingly some posts are missing from Facebook response.

Here is the facebook request used to get the posts list:

https://developers.facebook.com/tools/explorer?method=GET&path=LExpress%2Fposts%3Fsince%3D1504688400%26until%3D1504713600&version=v2.11

This returns only these three results:

 "data": [
        {
          "created_time": "2017-09-06T15:05:00+0000",
          "message": "Casernes de pompiers inondées, hôtels dévastés : l'ouragan Irma s'est abattu sur les îles de Saint-Barthélemy et Saint-Martin",
          "id": "9359316996_10155287552551997"
        },
        {
          "created_time": "2017-09-06T14:15:00+0000",
          "message": "Le gouvernement aussi a fait sa rentrée des classes",
          "id": "9359316996_10155287360111997"
        },
        {
          "created_time": "2017-09-06T09:45:00+0000",
          "message": "Persécutés, des dizaines de milliers de Rohingyas fuient la Birmanie",
          "id": "9359316996_10155286897911997"
        }
      ]

But where is the post published at 2017-09-06 12:56:32 ??

The following post has been published at 2017-09-06 12:56:32 +0000 and should be returned by Facebook in the specified date range:

  • since: 2017-09-06 11:00:00 +0000
  • until: 2017-09-06 18:00:00 +0000

https://developers.facebook.com/tools/explorer?method=GET&path=10155287271171997%3Ffields%3Did%2Cupdated_time%2Ccreated_time%2Cname&version=v2.11

{
  "id": "10155287271171997",
  "updated_time": "2017-09-06T12:56:32+0000",
  "created_time": "2017-09-06T12:56:32+0000",
  "name": "⭕ ALERTE — Ouragan Irma : black-out total sur les îles de Saint-Barthélémy et Saint-Martin

Centrales EDF hors-service, casernes de pompiers inondées

Suivez notre direct"
}

Why is that? Any thoughts?

Thx!

PS: as it is photos I also tried to get it from /photos route, but we don’t get any results…

    The answer is that Facebook will return a maximum of 600 posts per pages as explained in the page's feed limitations paragraph :

    The API will return a maximum of 600 ranked, published posts per year.

    Like what Ben Tazulev said, with the /{page-id}/posts endpoint there a limitation:

    The API will return approximately 600 ranked, published posts per year. For all posts query the /{page_id}/published_posts endpoint.

    -> https://developers.facebook.com/docs/graph-api/reference/v2.11/page/feed#read

    But when I tried to gather all my post with the /{page_id}/published_posts it worked!
