About this API
Connect Participant Service is the client API for Amazon Connect chat (not voice). Amazon Connect provides two customer contact channels: voice (uses SIP/WebRTC) and chat (uses this API). The frontend chat widget actually wraps Participant Service — SendMessage to send, UploadAttachment for files, CreateParticipantConnection to establish WebSocket for real-time pushes. Typical developers just use AWS's Chat Widget SDK without touching the underlying API. But for deep customization (independent contact-center UI), you'd use Participant Service directly.
