     accessToken: 'your_access_token',
     phoneNumberId: 'your_phone_number_id'
   });
   

Set Up Webhook Endpoints

   // Webhook handler for incoming messages

   app.post('/webhook', (req, res) => {
     const message = req.body;
     // Process incoming message
     res.status(200).send();
   });
   

Test Basic Functionality
