Graph API v25.0 deprecates impression metrics and updates Webhooks certificates
Meta is deprecating numerous unique impression metrics across Pages, Posts, Videos, and Stories, replacing them with new media view metrics when v26.0 launches. The update also deprecates the metadata query parameter and requires a trust store update for Webhooks mTLS certificates.

Who this affects
Advertisers and developers using the Graph API for Page, Post, Video, or Story Insights, as well as those receiving Webhooks events.
What to do
Update reporting to use new media view metrics before v26.0 is released. Stop using the metadata=1 query parameter by May 19, 2026. If using Webhooks mTLS, update your server trust store to include the new Meta Certificate Authority by March 31, 2026.
