## 💻 Technical Implementation

### Backend (Bot Service)

**File:** `services/steamBot.js`

```javascript
// Generate trade offer URL from offer ID
const tradeOfferUrl = `https://steamcommunity.com/tradeoffer/${offer.id}`;

// Include in bot response
return {
  offerId: offer.id,
  verificationCode,
  tradeOfferUrl,  // ← New field
  botId: this.botId,
  // ...
};
```

**WebSocket Notifications:**
All trade events now include `tradeOfferUrl`:
- `trade_sent`
- `trade_confirmed`
- `trade_created`

---

### Backend (Inventory Routes)

**File:** `routes/inventory.js`

**Development Mode:**
```javascript
const mockOfferId = `DEV_${Date.now()}`;
const mockTradeOfferUrl = `https://steamcommunity.com/tradeoffer/${mockOfferId}`;
```

**Trade Model:**
```javascript
const trade = new Trade({
  offerId,
  tradeOfferUrl,  // ← Saved to database
  verificationCode,
  // ...
});
```

**API Response:**
```json
{
  "success": true,
  "trade": {
    "tradeId": "...",
    "offerId": "...",
    "verificationCode": "A3X9K2",

  }
}
```
