Twillio SMS forwarding Slack bot with webhook

I have enabled incoming web hooks on Slack API incoming web-hooks. Webhook URLs for Your Workspace:

INSTRUCTIONS:

To dispatch messages with your webhook URL, send your message in JSON as the body of an application/json POST request.

Add this webhook to your workspace below to activate this curl example.

Sample curl request to post to a channel:

curl -X POST -H 'Content-type: application/json' --data '{"text":"Hello,     World!"}' https://hooks.slack.com/services/T0AFATG95/B73FDS5R6V/hFApP

(token is incomplete).

When i send the POST request it works!

APP 2:18 PM Hello, World!

Now I want to have Twillio send this POST request to slack using a web-hook or TwiML. ??? This is basically a relay to the slack URL. how do I make a POST request to that URL, so the message sent to the twillio # is sent in the body?

Under twillio phone settings I select what happens when:

A message comes in Webhook [WEB HOOK GOES HERE] HTTP POST

OR I CAN USE:

TwiML Bin instead and assign it in the twilio phone settings.

If I cannot achieve this I will use a lambda function to do it, I just though there might be a way to achieve this since i do not manipulate anything about the message.

Solution

  • You can do this with a Twilio Function, here is the code for the function: 

    const got = require('got');

exports.handler = function(context, event, callback) {

  const requestBody = {
    text: event.Body
  };

  got.post('https://hooks.slack.com/services/T0AFATG95/B73FDS5R6V/hFApP', {
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(requestBody)
  })
    .then(response => {
      let twiml = new Twilio.twiml.MessagingResponse();
      twiml.message("Your message has been forwarded to Slack.");
      callback(null, twiml);
    })
    .catch(err => {
      callback(err);
    });
};
