What can the Zapier API key read in my BytePhase account?

A Zapier key is the only BytePhase key type that can read data: recent customers, leads, repairs, payments, status changes and outsourced repairs, plus a customer search. That is what makes the triggers work. It cannot touch invoices, inventory, settings, billing or employees. Never reuse a Zapier key on a website or WordPress plugin; those get their own create-only keys.
