Integration Guide

Quick Setup

1. Copy your WebSocket URL from the ScaleSync Pro Android app
2. Connect to the WebSocket to receive real-time weight data
3. Integrate the data into your shipping workflow

JavaScript Integration

Add this code to your web application to connect to your scale:

// Get scale URL (typically stored after initial QR code scan)
const scaleUrl = "wss://scale-api.rsrchgk.com/channel/your-channel-id/ws";

// Initialize WebSocket connection
const ws = new WebSocket(scaleUrl);

// Handle incoming weight data
ws.addEventListener('message', (event) => {
  const data = JSON.parse(event.data);
  
  if (data.weights) {
    // Access weight in various units
    const weightLbs = data.weights.lbs;
    const weightKg = data.weights.kg;
    const weightOz = data.weights.oz;
    
    // Update your UI with the weight
    document.getElementById('package-weight').textContent = 
      `${weightLbs.toFixed(2)} lb`;
  }
});

// Handle connection events
ws.addEventListener('open', () => {
  console.log('Connected to scale');
});

ws.addEventListener('close', () => {
  console.log('Disconnected from scale');
});

API Response Format

The WebSocket sends JSON data in this format:

{
  "weights": {
    "lbs": 0.33,
    "kg": 0.15,
    "oz": 5.28,
    "g": 149.69,
    "mg": 149685.41
  },
  "device": {
    "vendorId": 9332,
    "productId": 1360,
    "manufacturerName": "Stamps.com",
    "productName": "SDC-550 Digital Scale"
  },
  "report": {
    "status": "POSITIVE",
    "unit": "oz",
    "weight": 5.28
  }
}

HTML Example

Here’s a simple HTML component to display weight:

<div class="weight-display">
  <h3>Package Weight</h3>
  <div class="weight-value">
    <span id="package-weight">0.00</span> lb
  </div>
</div>

Best Practices

• Store the WebSocket URL in localStorage for persistence
• Reconnect when the page becomes visible after being hidden
• Handle connection errors gracefully
• Only positive, stable weights will be transmitted
• Keep your Android device connected to power for reliable operation
