WebHook in Twilio API

Question

I can't find how to set up or change the Webhook through API. Is it possible to change it, set it when I am buying a number, or select one Webhook URL for all numbers?

I tried to find this info in the documentation but there was helpful to me

Answer 1

Yes, you can do that with the following command from the CLI:

twilio phone-numbers:update <TWILIO_NUMBER> --voice-url https://xxxxxxxx.ngrok.io --sms-url https://xxxxxxxx.ngrok.io

or with Node

const accountSid = process.env.TWILIO_ACCOUNT_SID;
const authToken = process.env.TWILIO_AUTH_TOKEN;
const client = require('twilio')(accountSid, authToken);

client.incomingPhoneNumbers('PNXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX')
  .update({voiceUrl: 'https://www.your-new-voice-url.com/example'})
  .then(incoming_phone_number => console.log(incoming_phone_number.friendlyName));

You can find other snippets in the docs (scroll to "Example 2 Update IncomingPhoneNumber to use a new Voice URL").

PS: If you want to reuse the same configuration for multiple phone numbers, you might want to see whether TwiML Apps can help you too.

Answer 2

You will have to log into your Twilio console.

From the Develop tab, select Phone Numbers, then Manage > Active Numbers.

You can set the default Webhook (and back-up alternate Webhook) by clicking on the desired number and entering it under the respective Phone or (if available) SMS fields. You will likely have to set the Webhook (takes 2 seconds) for each phone number purchased as the default is the Twilio Demo URL (replies back with Hi or something)

The nature of a Webhook should allow any change in functionality to be done externally (on your end) through your Webhook script's functionality and thus dynamically changing the Webhook URL through the API on a case-by-case basis is discouraged and frankly should not be necessary. Someone may correct me if mistaken.
