app.listen(3000, () => console.log('Server listening on port 3000')); This example and advice are quite general. The actual implementation would depend heavily on your specific requirements, the technology stack you're comfortable with, and any existing infrastructure.

app.post('/track', (req, res) => { const { subacc, clickid, data } = req.body; // Here you'd typically save data to a database console.log(subacc, clickid, data); res.send('Tracked successfully'); });

// Assuming you're using a body parser middleware app.use(express.json());
