public_base_urlstring nullable required
This deployment's own externally-reachable URL, used to build links in outgoing mail.
readyboolean required
Whether a message carrying a link back to this deployment can be sent, which is what every message the control plane sends needs. Matches 'mail_ready' on /v1/bootstrap.
transportstring required
