Send SMS

You can use Functions to send SMS messages.

// Description
// Send a single SMS

exports.handler = function (context, event, callback) {
  // Make sure under Functions Settings tab:
  // "Add my Twilio Credentials (ACCOUNT_SID) and (AUTH_TOKEN) to ENV" is CHECKED

  const twilioClient = context.getTwilioClient();

  // Pass in From, To, and Body as query parameters
  // Example: https://x.x.x.x/<path>?From=%2b15095550100&To=%2b15105550100&Body=Hello%20World
  // Note URL encoding above
  let from = event.From || '+15095550100';
  // If passing in To, make sure to validate, to avoid sending SMS to unexpected locations
  let to = event.To || '+15105550100';
  let body = event.Body || 'Hello World!';

      body: body,
      to: to,
      from: from,
    .then((message) => {
      console.log('SMS successfully sent');
      return callback(null, 'success');
    .catch((error) => {
      return callback(error);
