Telegram Bot Inline Keyboard with Dynamic Menus & Rating System

🤖 Telegram Bot with Dynamic Menus & Rating System

What It Does

This n8n workflow creates an interactive Telegram bot with:

• Dynamic inline keyboards that respond to user clicks
• 5-star rating system for collecting feedback
• Personalized responses using the user's actual name
• Multi-level menu navigation (Main → Settings → Profile, etc.)
• Real-time message updates when buttons are clicked

How It Works

1. Receives messages via Telegram webhook trigger node
2. Extracts user data (name, ID, message type)
3. Builds dynamic menus based on user actions
4. Sends/updates messages with inline keyboards
5. Handles button clicks without page refresh

🎨 Customization Guide

Add New Menu Items

In the "Prepare Response" Function node, add new cases:
case 'your_feature':
responseText = 'Your feature description';
keyboard = [
[{ text: '🎯 Button 1', callback_data: 'action1' }],
[{ text: '🔙 Back', callback_data: 'main' }]
];
break;

Modify Rating Options

Change star buttons to numbers or emojis:
// Current: ⭐⭐⭐
// Alternative: 1️⃣ 2️⃣ 3️⃣ or 👎 👍

Change Bot Responses

• Edit responseText for message content
• Modify keyboard arrays for button layout
• Add HTML formatting: <b>bold</b>, <i>italic</i>

💡 ++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
