Try it — sandbox: every call answers a deterministic, provenance-labeled simulated payload ({ environment, simulated } in the body). Force any documented outcome with the magic triggers. Going live is a connect, never a ballot: submit the credential at integrates.vin (dealer systems) or connects.vin (consumer accounts) — submissions enter the activation queue and rank live rollout.
