# Live Sync App Version (v1)

> Trigger a live sync for the active preview instance of a draft app version. The caller provides the current commit IDs; the server syncs only what has changed since the last sync. Returns 404 if no active preview instance exists. No-op (triggered=false) if all provided commits are already up to date.
