The `twilio` notification platform enables sending notifications via SMS, powered by [Twilio](https://twilio.com).
The requirement is that you have setup [Twilio](/integrations/twilio/).
To use this notification platform in your installation, add the following to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
notify:
- name: NOTIFIER_NAME
platform: twilio_sms
from_number: E164_PHONE_NUMBER or SENDER_ID
```
{% configuration %}
from_number:
description: An [E.164](https://en.wikipedia.org/wiki/E.164) formatted phone number, like +14151234567. See [Twilio's guide to formatting phone numbers](https://www.twilio.com/help/faq/phone-numbers/how-do-i-format-phone-numbers-to-work-internationally) for more information. Alternatively, a sender ID can be used instead of a phone number. The sender ID must be formatted according to Twilio's guidelines. See [Twilio's guide to sender ID](https://support.twilio.com/hc/en-us/articles/223181348-Getting-started-with-Alphanumeric-Sender-ID) for more information. Do keep in mind that not all countries support sender ID. See [Twilio's page of supported countries](https://support.twilio.com/hc/en-us/articles/223133767-International-support-for-Alphanumeric-Sender-ID) for more information.

### Usage
Twilio is a notify platform and thus can be controlled by calling the notify service [as described here](/integrations/notify/). It will send a notification to all E.164 phone numbers in the notification **target**. See the notes above regarding the `from_number` configuration variable for information about formatting phone numbers. It's also possible to use `whatsapp:+123456789` for sending notifications to a Whatsapp user.
Media can be included with messages by setting the optional `media_url` variable. Only `.gif`, `.png`, or `.jpeg` content are supported, according to the Twilio documentation and this feature is [only supported in the US and Canada.][mms]
