version_added: "1.6"
module: twilio
short_description: Sends a text message to a mobile phone through Twilio.
description:
   - Sends a text message to a phone number through the Twilio messaging API.
notes:
   - This module is non-idempotent because it sends an email through the
     external API. It is idempotent only in the case that the module fails.
   - Like the other notification modules, this one requires an external
     dependency to work. In this case, you'll need a Twilio account with
     a purchased or verified phone number to send the text message.
options:
  account_sid:
    description:
      user's Twilio account token found on the account page
    required: true
  auth_token:
    description: user's Twilio authentication token
    required: true
  msg:
    description:
      the body of the text message
    required: true
  to_number:
    description:
      one or more phone numbers to send the text message to,
      format +15551112222
    required: true
  from_number:
    description:
      the Twilio number to send the text message from, format +15551112222
    required: true
  media_url:
    description:
      a URL with a picture, video or sound clip to send with an MMS
      (multimedia message) instead of a plain SMS
    required: false
