Integration of WhatsApp Web into Our CRM Tool

[muhammedadnanv]

Hello Team,

We are embarking on an exciting project to integrate WhatsApp Web into our CRM tool to enhance our communication capabilities and streamline interactions. To ensure a successful integration, here are some key points, tasks, and code examples to guide our development:

Objective:
Integrate WhatsApp Web with our CRM to enable real-time messaging, automate responses, and improve user engagement.

Current Setup:
We have access to the WhatsApp Business API and a verified Business Account.
API credentials and setup details are available.
Integration Tasks:
Set Up Development Environment:

Install necessary libraries and set up the server.
Webhook Configuration:

Implement and test the webhook to receive incoming messages.
Message Handling:

Develop functionality to send and receive messages via the WhatsApp API.
User Interface:

Design and integrate a chat interface within the CRM.
Data Privacy and Security:

Ensure compliance with data protection regulations and secure API interactions.
Code Example:
Here is a basic Node.js code snippet to get started with WhatsApp Web integration. This example sets up a server to handle incoming messages and send responses using the WhatsApp Business API.

javascript
Copy code
// server.js

const express = require('express');
const bodyParser = require('body-parser');
const axios = require('axios');

const app = express();
const port = 3000;

// Your WhatsApp Business API credentials
const WHATSAPP_API_URL = 'https://your-whatsapp-api-url.com/v1/messages';
const WHATSAPP_API_TOKEN = 'your-whatsapp-api-token';

// Middleware
app.use(bodyParser.json());

// Webhook to receive incoming messages
app.post('/webhook', async (req, res) => {
const message = req.body;

console.log('Received message:', message);

// Handle the incoming message and respond
if (message && message.messages && message.messages.length > 0) {
    const incomingMessage = message.messages[0];
    
    // Example: send a reply
    await sendMessage(incomingMessage.from, 'Thank you for your message!');
}

res.sendStatus(200);

});

// Function to send a message
const sendMessage = async (to, text) => {
try {
await axios.post(
WHATSAPP_API_URL,
{
messaging_product: 'whatsapp',
to: to,
text: { body: text },
},
{
headers: {
'Authorization': Bearer ${WHATSAPP_API_TOKEN},
'Content-Type': 'application/json',
},
}
);
console.log(Message sent to ${to});
} catch (error) {
console.error('Error sending message:', error.response ? error.response.data : error.message);
}
};

// Start the server
app.listen(port, () => {
console.log(Server running on port ${port});
});
