Forward Email WebSockets API
Real-time push notifications via WebSocket. Connect to the /v1/ws endpoint to receive live events. Authentication is optional: authenticated clients receive per-alias events (IMAP, CalDAV, CardDAV) and global broadcast events, while unauthenticated clients receive only global broadcast events (e.g. newRelease). Supports 20 distinct event types covering message delivery, moves, copies, flag changes, expunges, mailbox CRUD, calendar CRUD, calendar event CRUD, contact CRUD, address book CRUD, and app release broadcasts from the Forward Email Mail App (https://github.com/forwardemail/mail.forwardemail.net).
