  oauth2_flows: []
  notes: >-
    Yuno uses paired header API keys — a public key for client-side/SDK context
    and a private secret key for server-side calls — plus an account-code header
    that identifies the merchant account. Sandbox and production use different
    keys. There is no OAuth2 flow on the core payments API (OAuth2 exists only as
    an optional authentication mode for outbound webhook delivery). Keys are
    issued from the Yuno Dashboard (dashboard.y.uno/developers).
