Authentication is a LoopBack-style flow: POST username + API key to /api/customers/login to receive an access token, then pass that token in the `Authorization` header (raw token value, NOT a Bearer prefix) on every subsequent call. This document models a representative subset of the marketplace; the full catalog is documented at https://docs.signzy.com.\n\nContact Support:\n Name: Signzy Support", "schema":
