Configuring Twilio Client

Use your Twilio credentials to configure the Twilio client in your JavaScript application.

const accountSid = 'your_account_sid';
const authToken = 'your_auth_token';
const client = require('twilio')(accountSid, authToken);

Use the Twilio client to send an SMS message.

    body: 'Hello from Twilio!',
    from: 'your_twilio_phone_number',
    to: 'recipient_phone_number'
  .then(message => console.log(`Message sent: ${message.sid}`))
  .catch(error => console.error(`Error sending message: ${error.message}`));
  1. Handling Successful Responses
    • Retrieve and log the message SID for successful message delivery.
      .then(message => console.log(`Message sent: ${message.sid}`))
  2. Handling Errors
    • Implement error handling to manage failed message deliveries.
      .catch(error => console.error(`Error sending message: ${error.message}`));
  3. Adding Media to SMS
    • Attach media files to your SMS messages.
    body: 'Check out this image!',
    from: 'your_twilio_phone_number',
    to: 'recipient_phone_number',
    mediaUrl: ''
