3. Connect target applications
4. Configure triggers dan actions
5. Test dan activate
Make (formerly Integromat):
Advantages:

– Multi-app orchestration
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

    last_message TIMESTAMP,
    status VARCHAR(50),
    assigned_agent VARCHAR(100),
    tags TEXT[]
);
