Symbl's APIs empower developers to enable:

• Real-time analysis of free-flowing discussions to automatically surface highly relevant summary discussion topics, contextual insights, suggestive action items, follow-ups, decisions, and questions.
• Voice APIs that makes it easy to add AI-powered conversation intelligence to either telephony or WebSocket interfaces.
• Conversation APIs that provide a REST interface for managing and processing your conversation data.
• Summary UI with a fully customizable and editable reference experience that indexes a searchable transcript and shows generated actionable insights, topics, timecodes, and speaker information.

• Symbl appSecret and appId - If you don't have a Symbl account for signup look it up in this Link.
• Twilio account - If you don't have a Twilio account for signup look it up in this Link.
• Twilio purchaced phone number - If you don't have a Twilio purchaced phone number you can look for these steps Link.
• ngrok installed with your account - If you dont have ngrok you can follow this Link.

• Stream Server that connect Twilio Media Stream to Symbl using WebSocket and exposes a REST API of Symbl’s real-time events to a Client server.
• Up to 4 speaker can call to a Twilio number and start a conversation, so each phone stream get into a separate WebSocket channel that is directed to Symbl and once conversation transcripts messages, topics or insights are identified they are immediatly addressed in real-time to another clientServer that servers as a webhook point.
