Webhook Development dan Configuration

Technical setup untuk message receiving.

Webhook Concept:

Public URL yang receive POST requests
Called oleh WhatsApp API saat events occur
Real-time message delivery
Event-driven architecture

Webhook Setup:

1. Create Endpoint:

Using Express.js (Node.js):

const express = require('express');
const app = express();

app.use(express.json());

app.post('/webhook/whatsapp', (req, res) => {
    const message = req.body;
    
    // Process message
    handleIncomingMessage(message);
    
    res.sendStatus(200);
});

app.listen(3000);

Using Flask (Python):

from flask import Flask, request

app = Flask(__name__)

@app.route('/webhook/whatsapp', methods=['POST'])
def whatsapp_webhook():
    data = request.json
    
    # Process message
    process_message(data)
    
    return 'OK', 200

if __name__ == '__main__':
    app.run(port=3000)

2. Verify Webhook:

Verification Challenge:

@app.route('/webhook/whatsapp', methods=['GET'])
def verify_webhook():
    mode = request.args.get('hub.mode')
    token = request.args.get('hub.verify_token')
    challenge = request.args.get('hub.challenge')
    
    if mode == 'subscribe' and token == VERIFY_TOKEN:
        return challenge, 200
    else:
        return 'Verification failed', 403

3. Handle Messages:

Message Processing:

def process_message(data):
    entry = data['entry'][0]
    changes = entry['changes'][0]
    value = changes['value']
    
    if 'messages' in value:
        message = value['messages'][0]
        phone = message['from']
        text = message['text']['body']
        
        # Route ke appropriate handler
        route_message(phone, text)

4. Security:

HTTPS required
Signature verification
IP whitelisting
Rate limiting
Authentication

Database Integration dan Data Management

Storing dan managing WhatsApp data.

Database Schema:

CREATE TABLE conversations (
    id SERIAL PRIMARY KEY,
    phone_number VARCHAR(20),
    customer_name VARCHAR(100),
    last_message TIMESTAMP,
    status VARCHAR(50),
