Subscribe to real-time WhatsApp events from WhatsTeam — inbound messages, delivery and read receipts, status changes, campaign events, chat assignment changes, device state, and more. Use when the user wants live automation triggered by WhatsApp events (auto-replies, CRM sync, alerting, opt-out handling, multi-agent routing). Covers subscription via the REST API, payload shapes, HMAC signature verification, retries, and how to expose a public endpoint locally for development.
