Do gta online heists unlock gta v content?

The heist missions in GTA Online are separate from the single‑player GTA V storyline. Completing them provides in‑game rewards such as money, vehicles, weapons, and customization options, but does not unlock new missions, vehicles, or features in the GTA V single‑player experience. Players who finish heists can access the associated online content and progression, but there is no direct crossover that adds new GTA V content to the offline mode.
