arzbridge calls — Developer Integration Guide

Add real-time video, voice, and data to your app in minutes. arzbridge calls is a managed WebRTC platform: your backend asks our API for a join token, and your app (web, mobile, Flutter, etc.) connects directly to our media servers with that token.

You only integrate two things: (1) a couple of REST calls from your backend, and (2) a LiveKit client SDK in your app. That's it.

The integration model (read this first)

            ┌─────────────┐        1. request token (API key+secret)
            │ YOUR BACKEND │ ───────────────────────────────────────►  arzbridge API
            │ Node/Laravel │ ◄───────────────────────────────────────  { token, ws_url }
            └──────┬──────┘        2. token returned
                   │ 3. your app asks your backend for a token
                   ▼
            ┌─────────────┐        4. connect with token
            │  YOUR APP    │ ─────────────────────────────────────►   arzbridge media
            │ Flutter/Web  │ ◄═══════════ live audio/video/data ═════►  (LiveKit)
            └─────────────┘

Golden rule: your API key + secret live only on your backend. Your app (Flutter, web, mobile) never sees them — it only receives short-lived tokens from your backend.

What you'll need

Thing Where it comes from
API key + secret Provided to you by arzbridge (one pair per project)
API base URL https://calls.arzbridge.com/api/v1
WebSocket URL (for clients) wss://calls.arzbridge.com (also returned in token responses)

60-second quickstart

# 1) Your backend gets a token (server-to-server)
curl -s https://calls.arzbridge.com/api/v1/tokens \
  -H "Authorization: Bearer YOUR_API_KEY:YOUR_API_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"room":"my-first-room","identity":"user-123","name":"Alice"}'
# -> { "data": { "token": "...", "ws_url": "wss://calls.arzbridge.com", ... } }

// 2) Your Flutter app joins with that token
final room = Room();
await room.connect('wss://calls.arzbridge.com', token);
await room.localParticipant?.setMicrophoneEnabled(true);
await room.localParticipant?.setCameraEnabled(true);

That's a working call. The rest of this guide makes it production-grade.
