# Update guest annotations for a preview file

**PUT /shared/playlists/{token}/annotations**

Update preview file annotations in the context of a shared playlist. Reuses the same additions/updates/deletions diff format as the manager-facing /actions/preview-files/<id>/update-annotations route, so concurrent edits stay safe via the Redis lock.
