[{ text: '🔙 Back', callback_data: 'main' }]
];
break;

💡 ++Key Features Demonstrated++

HTTP Request workaround for dynamic keyboards (n8n Telegram node limitation)
Callback query handling to prevent loading animations
Message editing vs sending new messages
User data extraction from Telegram API
Switch-case menu routing for scalable navigation

⚠️ ++Important Notes++

Limitation: n8n's native Telegram node doesn't support dynamic inline keyboards, this is why need to use HTTP nodes.
Solution demonstrated: Use HTTP Request node with Telegram Bot API directly
