Supported Python Versions

This library supports the following Python implementations:

  • Python 2.7
  • Python 3.4
  • Python 3.5
  • Python 3.6
  • Python 3.7
  • Python 3.8


Install from PyPi using pip, a package manager for Python.

pip install twilio

Don't have pip installed? Try installing it, by running this from the command line:

$ curl | python

Or, you can download the source code (ZIP) for twilio-python, and then run:

python install

You may need to run the above commands with sudo.

Getting Started

Getting started with the Twilio API couldn't be easier. Create a Client and you're ready to go.

API Credentials

The Twilio needs your Twilio credentials. You can either pass these directly to the constructor (see the code below) or via environment variables.

from import Client

client = Client(account, token)

Alternately, a Client constructor without these parameters will look for TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN variables inside the current environment.

We suggest storing your credentials as environment variables. Why? You'll never have to worry about committing your credentials and accidentally posting them somewhere public.

from import Client
client = Client()

Make a Call

from import Client

client = Client(account, token)

call = client.calls.create(to="9991231234",

Send an SMS

from import Client

client = Client(account, token)

message = client.messages.create(to="+12316851234", from_="+15555555555",
                                 body="Hello there!")

Handling Exceptions

from import Client
from twilio.base.exceptions import TwilioRestException

client = Client(account, token)

  message = client.messages.create(to="+12316851234", from_="+15555555555",
                                   body="Hello there!")
except TwilioRestException as e:

Generating TwiML

To control phone calls, your application needs to output TwiML.

Use twilio.twiml.Response to easily create such responses.

from twilio.twiml.voice_response import VoiceResponse

r = VoiceResponse()
r.say("Welcome to twilio!")
<?xml version="1.0" encoding="utf-8"?>
<Response><Say>Welcome to twilio!</Say></Response>

Docker Image

The Dockerfile present in this repository and its respective twilio/twilio-python Docker image are currently used by Twilio for testing purposes only.
