Get Started

Install the Twilio Python Helper Library

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

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 setup.py 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:

send_sms.py
from twilio.rest import TwilioRestClient

# Your Account Sid and Auth Token from twilio.com/user/account
account_sid = "AC32a3c49700934481addd5ce1659f04d2"
auth_token  = ""
client = TwilioRestClient(account_sid, auth_token)

message = client.sms.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:

python send_sms.py

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.

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

try:
    client = twilio.rest.TwilioRestClient(account_sid, auth_token)
    from twilio.rest import TwilioRestClient

    message = client.sms.messages.create(
        body="Hello World",
        to="+14159352345",
        from_="+14158141829"
    )
except twilio.TwilioRestException as e:
    print e
