There's usually **no protection whatsoever**.\n\nThis is dangerous when your bot:\n- 🤖 Uses AI APIs (OpenAI, Claude) - **costs money per message**\n- 💰 Calls paid services - **drains your credits**\n- 🔐 Accesses sensitive data - **security risk**\n- 📊 Processes heavy workloads - **server overload**\n\n## ✅ The Solution\n\n**BotGuard** protects your bot by:\n\n1️⃣ **Whitelist Control** - Only allowed User IDs can use the bot\n2️⃣ **Admin Alerts** - Get notified of unauthorized access attempts\n3️⃣ **Flexible Messages** - Customize denied/success responses\n4️⃣ **Easy Setup** - Just add User IDs to the code\n\nThis is a **simple but effective** authorization layer that sits before your main workflow, preventing unauthorized usage and protecting your resources.\n\n💡 **Modify messages** to suggest users request access, or keep it restricted - your choice!"

User sends message to bot → Gets denied\n2. Denied message shows: `Your User ID: 123456789`\n3. Copy ID and add to arrays above\n\n## 🔄 Export/Import\n\n**Export:** Workflow menu (⋮) → Download → Save JSON\n**Import:** New workflow → Menu (⋮) → Import from File → Configure Telegram credentials\n\n## 🚨 Admin Notifications\n\n**Triggers when:** Unauthorized user tries to access bot  \n**Sends to:** All users in `Administrators` array  \n**Includes:** Name, User ID, Language, Time, Message text\n\n## 🎯 Example Users (Replace with Real Data)\n\n- `111111111, 222222222, 333333333` - Mock placeholder IDs\n- `john_doe, jane_smith, admin_user` - Example usernames\n- Replace these with your actual users!"
