Slack Real Time Messaging API MASTER RECORD

Slack, the team collaboration and messaging chat app, hosts the Slack Real Time Messaging (RTM) API for embedding real time chat functionality within clients. This WebSocket based API enables developers to programmatically receive events as well as send messages using Slack in real time. Once connected, the server will provide a continuous stream of events, recent messages, and updates made to the Slack team. The websocket connection uses JSON for requests and responses, and uses OAuth2 for authentication.
