How do I connect BytePhase to Zapier?

With an API key. BytePhase generates it, shows it once, and stores only a SHA-256 hash — afterwards you see just its last four characters. You paste it into your Zapier connection along with your API base URL, and every request is then authenticated, rate-limited and scoped to your shop. A built-in connection test confirms the link before you switch a Zap on.
