How does “Issuing it” work on the Company Letters page?

Save keeps the letter against your name. Download PDF renders it on the server. Send for signature files that PDF as a draft in Saral Sign and deep-links to its editor, where the signers and fields are placed and the envelope sent; the letter's status here shows it has gone. A letter is private to its author: nobody else sees it on Past letters, and the API never lists it to anyone else. Where: Company Letters (/accounts/letters).
