The official documentation for the Facebook APIs can be found here.

Getting "(#100) Pages Public Content Access requires either app secret proof or an app token" issue when calling Facebook API?

I am developing an app that syncs with users Facebook account and fetches Facebook page information. Initially, app asks for Login with Facebook and gets page list. After getting pages I am calling API to get posts associated with each page. Once I get post details then I am calling insight APIs to get insights of each post.
This flow working fine with development mode but when I switch to Live mode I am getting the following error

      Client error: `GET https://graph.facebook.com/v4.0/100575944711552/feed` resulted in a `400 Bad Request` response:{"error":{"message":"(#100) Pages Public Content Access requires either app secret proof or an app token","type":"OAuthE (truncated...)
 {"userId":1,"email":"[email protected]","exception":"[object] (GuzzleHttp\Exception\ClientException(code: 400): Client error: `GET https://graph.facebook.com/v4.0/100575944711552/feed` resulted in a `400 Bad Request` response:
{"error":{"message":"(#100) Pages Public Content Access requires either app secret proof or an app token","type":"OAuthE (truncated...)

From the details what I observed I am getting this error while using,

GET /v5.0/{page-id}/feed HTTP/1.1
Host: graph.facebook.com

this endpoint. I am currently having 2 permissions approved,

  1. manage_pages 2. read_insights
    and app review team rejected 2 permissions saying the request is invalid and for this use case we don’t require this which are,
    1.Page Mentions 2. user_posts

Can anyone help me to understand what is the exact issue?

    I have fixed this issue. Everything is fine but the only issue is when authenticating with facebook login I needed to include "manage_page" permission in scope section.

    I also appear this error. for me, I found that since graph api v5.0, request has changed. The docs said:

    Page Public Content Access

    This change applies to v5.0+

    Requests made to endpoints that require the Page Public Content Access feature must be made with either an App Access Token or include the app’s App Secret. If the calling app has been granted the manage_pages permission however, an app access token or app secret is not required.

    If you only retrieve public data. You can use requests by app access token quick fixed. But if you want to get more. You need to follow the docs update. 🙂

    I had the same problem. Upon reacting to their damn changes yet again (manage_pages is not a thing anymore). I only had pages_manage_metadata but not pages_read_engagement to actually read the content on the page… -.-
