- Use ChatGPT as LinkedIn content co-pilot (safely)
- Choose between direct API or managed services
- Follow platform policies to avoid bans
- Measure ROI with clear metrics
📦 Prerequisites & Setup
Before starting, gather these essential accounts:
- OpenAI API key - From platform.openai.com
- WhatsApp Business Account - Meta Cloud API or Twilio
- Webhook URL - HTTPS endpoint for receiving messages
- Server environment - Node.js/Python or no-code platform
🤖 WhatsApp Cloud API Integration
Step 1: Create Meta Developer App
Go to developers.facebook.com and create a new business app with WhatsApp product enabled.
Step 2: Configure Webhook
Set up your webhook URL and verification token. Your server must handle the verification challenge.
Step 3: Implement Message Handling
Process incoming messages and call ChatGPT API.
💻 Code Examples
Node.js Webhook Server
const express = require('express');
const axios = require('axios');
const app = express();
app.use(express.json());
// Webhook verification
app.get('/webhook', (req, res) => {
const token = req.query['hub.verify_token'];
const challenge = req.query['hub.challenge'];
if (token === process.env.VERIFY_TOKEN) {
res.send(challenge);
} else {
res.sendStatus(403);
}
});
// Handle incoming messages
app.post('/webhook', async (req, res) => {
const message = req.body.entry?.[0]?.changes?.[0]?.value?.messages?.[0];
if (message?.type === 'text') {
const response = await axios.post(
'https://api.openai.com/v1/chat/completions',
{
model: 'gpt-3.5-turbo',
messages: [
{role: 'system', content: 'You are a helpful assistant.'},
{role: 'user', content: message.text.body}
]
},
{headers: {Authorization: `Bearer ${process.env.OPENAI_KEY}`}}
);
// Send reply back to WhatsApp
await sendWhatsAppMessage(message.from, response.data.choices[0].message.content);
}
res.sendStatus(200);
});
app.listen(3000);
📞 WhatsApp via Twilio
Twilio provides a managed solution with these advantages:
| Feature | Twilio | Direct API |
|---|---|---|
| Setup Complexity | Easy | Moderate |
| Number Management | Managed | Self-managed |
| Pricing | Per message | Free tier available |

ChatGPT automatically detects and responds in the user's language. Include this in your system prompt: "Respond in the same language as the user."
Yes, but you must: disclose AI usage, provide opt-out options, implement data retention policies, and consider privacy regulations.
