The Twilio Python Helper Library

The twilio-python helper library lets you write Python code to make HTTP requests to the Twilio API.

This library is open source, so if you find a feature missing or a bug, we encourage you to contribute back to the twilio-python project hosted on Github.

More Documentation

The Rest API Documentation has examples written in Python for every kind of action you could take with the Twilio API. You should start there if you know what you want to do with the Python library.

If you'd like to learn more about how Twilio works, or for inspiration about what to build, try the Python quickstarts.

You may also want to refer to the open source twilio-python specific documentation for more details about the functions and classes contained in the module.


The easiest way to install twilio-python is from PyPi using pip, a package manager for Python. Simply run this in the terminal:

pip install twilio

If you get a pip: command not found error, you can also use easy_install. Run this in your terminal:

easy_install twilio

Or, you can download the source code (ZIP) for twilio-python, and then install the library by running:

python install

in the folder containing the twilio-python library.

"Permission Denied"

If the command line gives you a big long error message that says Permission Denied in the middle of it, try running the above commands with sudo, ex. sudo pip install twilio.

Testing your installation

Try sending yourself an SMS message. Save the following code in a plain text editor on your computer:
from import TwilioRestClient

# Your Account Sid and Auth Token from
account_sid = "AC32a3c49700934481addd5ce1659f04d2"
auth_token  = "{{ auth_token }}"
client = TwilioRestClient(account_sid, auth_token)

message = client.messages.create(body="Jenny please?! I love you <3",
    to="+14159352345",    # Replace with your phone number
    from_="+14158141829") # Replace with your Twilio number
print message.sid

In the terminal, cd to the directory containing the file you just saved, then run:


Using the Module

Try the Python quickstarts and refer to the open source twilio-python specific documentation for details about the functions and classes contained in the library.

Handling Exceptions

If the Twilio API returns a 400 or a 500 level HTTP response, the twilio-python library will throw a TwilioRestException. 400-level errors are normal during API operation ("Invalid number", "Cannot deliver SMS to that number", for example) and should be handled appropriately.

import twilio

    client =, auth_token)

    message = client.messages.create(
        body="Hello World",
except twilio.TwilioRestException as e:
    print e
