# Review application form draft undo

`matchmaking_application_editor.review_undo`

Review reversing your Portal's latest reversible draft structure edit. This does not publish, notify participants or restore deleted answers. Review these effects before calling undo with the returned live_revision, draft_revision and review_digest. This toolset requires a specific grant and is not assigned by default; request access through Support. Saved drafts and published question changes can mark earlier matching results as out of date. These tools do not rerun matching, contact recipients or create Deals.
