WhatsApp Bots

WhatsApp bots are automated chat programs that interact with users on WhatsApp. They are widely used for customer support, marketing, e-commerce, and personal assistant tasks. These bots function using AI, predefined commands, or rule-based logic.

Benefits of WhatsApp Bots

• 24/7 Customer Support: Respond to queries any time of the day.
• Business Automation: Automate bookings, FAQs, and order tracking.
• Marketing & Sales: Send promotional messages and collect leads.
• AI-Powered Assistance: Use machine learning to enhance responses.

Programming Languages Used

WhatsApp bots can be created using different languages, including:

• JavaScript (Node.js): Popular for creating bots using WhatsApp Web APIs.
• Python: Used with libraries like Twilio, Flask, and Selenium.
• PHP: Used for WhatsApp business integration.

How to Set Up a WhatsApp Bot

1. Register for a WhatsApp Business API account.
2. Choose a programming language and set up the bot framework.
3. Integrate a message-handling system.
4. Deploy the bot on a cloud server.

Security & Privacy

WhatsApp bots should comply with security protocols to protect user data. End-to-end encryption and GDPR compliance are necessary for safe communication.

Example: Creating a Simple WhatsApp Bot (Node.js)

            const { Client } = require('whatsapp-web.js');
            const qrcode = require('qrcode-terminal');

            const client = new Client();
            client.on('qr', qr => { qrcode.generate(qr, { small: true }); });
            client.on('ready', () => { console.log('Bot is ready!'); });
            client.on('message', msg => { if (msg.body === 'hi') msg.reply('Hello! How can I help?'); });
            client.initialize();
        

            // Example: Print "Hello, World!"
            console.log("Hello, World!");
        

            # Example: Print "Hello, World!"
            print("Hello, World!")
        

            
            
                
                
Hello, World!
            
        

            /* Example: Styling a heading */
            h1 {
                color: blue;
                font-size: 24px;
            }
        

            // Example: Java - Print "Hello, World!"
            class HelloWorld {
                public static void main(String[] args) {
                    System.out.println("Hello, World!");
                }
            }
