Cc and bcc on an envelope

cc / bcc in settings are plain addresses that are told about the envelope but never asked to sign — no link, no token:

"settings": {
  "documentId": "...", "subject": "...",
  "cc": ["sales@acme.example"],
  "ccNotifyOn": "completion"
}

ccNotifyOn / bccNotifyOn is "none" (default), "completion" (one email, with the signed PDF attached), or "everything" (every step: the send, each signature, a decline, the expiry, a revocation, a delegation, a failed invitation, the reminders and the completion; since 1.4). The same three words, one per person, are the levels of watchers (watchers). Every address on either list gets a mail of its own, so nobody sees the other addresses: cc and bcc behave the same, and both are kept so a request written for another service still fits. Separately from cc/bcc, your organisation is told when an envelope completes, at the addresses set in Settings (Notifications), unless that notice is switched off there. The mails to cc, bcc and watchers are written in the envelope's language (settings.language, else the organisation's).
