Using Postman to Test a Twilio Webtask

Question

Trying to replace my workplace's Twilio implementation with a temporary solution while we move from one platform to another, and I thought Webtask would be a great solution. I was very happy to see that there was a default Twilio template for webtask and thought I could get straight to work but for some reason, I can't get the template to work even with it's default functionality.

I'm worried that I'm not posting what's expected to the webtask. Here's the default code that sits on my webtask:

'use latest';
import twilio from 'twilio';
module.exports = (context, cb) => {
  // POST a json object with at least the following properties.
  const { body, to_number, from_number } = context.data;
  const { TWILIO_SID, TWILIO_AUTH_TOKEN } = context.secrets;
  
  var client = new twilio.RestClient(TWILIO_SID, TWILIO_AUTH_TOKEN);
  client.messages.create({
    body,
    to_number,
    from_number
  }, (err, message) => {
    message = message + " Goodbye World!";
    if (err) return cb(err);
    cb(null, message);
  });
};

And here's what my Postman looks like (with my Twilio phone number and personal phone number supplied to from_number and to_number in the actual code obv). Headers: postman-headers Body: postman-body

I've stored my Auth token and SID in the secrets area. When I make this post, I receive:

{
    "code": 400,
    "error": "Script returned an error.",
    "details": {
        "status": 400,
        "message": "A 'From' phone number is required.",
        "code": 21603,
        "moreInfo": "https://www.twilio.com/docs/errors/21603"
    },
    "message": "A 'From' phone number is required."
}

I've tried several things, like setting the from_number in the code like this const from_number = "+19999999999" except with a real number. Even so, I get the same 400 response (I also tried adding the SID as a username and the Auth Token as a password, as mentioned in this answer -- same result). I really want to get webtask working, if at all possible.

Twilio developer evangelist here.

When you're making the call to Twilio to send the message you are using the wrong attribute names. Instead of

client.messages.create({
    body,
    to_number,
    from_number
  }, (err, message) => { //... } );

it should be:

client.messages.create({
    body,
    to: to_number,
    from: from_number
  }, (err, message) => { //... } );

Twilio expects the attributes to be called to and from not to_number and from_number.

Let me know if this helps.
