About this API
Twilio Chat launched in 2016 as a programmable chat platform, abstracting WebSocket persistence, message storage, push notifications, and channel/member management. In 2020 Twilio shipped Conversations — Chat's evolution that unifies SMS, WhatsApp, MMS, and chat into a single "conversation" primitive. Chat v1 entered EOL; new projects should adopt Conversations. The Chat v1 API still works but receives no new features and lower SLA priority.
