Facebook post_impressions and post reach metrics no longer return data

post_impressions, post_impressions_unique, post_views and post_engaged_users return errors or nothing

Verified 2026-09-04 · Confirmed by 0 builders · Trust 50/100

Cause

Meta deprecated post-level impressions, unique impressions, views and engaged users for Facebook Page posts on 2026-06-16. It is a platform change, not a token or permission problem.

Fix

Drop those metrics. Use the ones that still answer, and use Instagram insights for reach.

Apply

GET /{post-id}/insights?metric=post_clicks,post_reactions_by_type_total

Affects: Graph API, Facebook Page posts, from 2026-06-16
