Facebook graphic api post comment

Questions

Hi everyone,

​I’m using a self-hosted n8n (v.2.8.3) and I’m struggling with the Facebook Graph API.

​Goal: Upload a native photo to a Page and immediately post a link in the first comment.

​The Problem:

  1. ​The photo upload works perfectly via the photos edge.

  2. ​However, the subsequent request to post a comment returns: 403 - Forbidden: (#200) Permissions error.

​My Setup:

  • ​App Mode: Live.

  • ​Token: Permanent Page Access Token.

  • ​Permissions: pages_manage_posts, pages_read_engagement, pages_show_list.

  • ​Target IDs: I’ve tried both the post_id and the photo_id.

​Is a full App Review for pages_manage_engagement mandatory just to comment on my own Page’s photo posts? Or is there a specific path/workaround to avoid the 403 error on native photo objects?

​I want to avoid the feed edge to maintain high organic reach.

​Thanks!

Hi @King_Pyrros As far as u know that page permission is needed for you to post comments on posts, make sure to give right permission pages_manage_engagement , also this is applicable for page owner in live mode.

Thank you very much for the detailed guide. It seems that it is working even with the standard access of pages_manage_engagement.
