Python Quickstart: Making an Outgoing Call

To make a call, submit a POST request to the Calls resource.


The twilio-python library makes this very easy to do. Open a file called and write the following:
# Download the library from
from import Client

# Get these credentials from
client = Client(account_sid, auth_token)

# Make the call
call = client.api.account.calls\
      .create(to="+14085551234",  # Any phone number
              from_="+12125551234", # Must be a valid Twilio number


Then make the call by running the following in your Terminal:


Lets look at the details:

  • First over to the Twilio website and log into your Twilio Account page. On the Dashboard there is a section labeled "API Credentials". There you will find your Account SID and Auth Token. Copy those values and paste them into the Account SID and Auth Token variables.
  • We then instantiate a new client object, set the request method to 'POST', fill in the 'From', 'To' and 'Url' parameters in an associative array, and fire off the request to Twilio!

Call end callback

By default, your application does not get any notification when a call is complete, if the line is busy, or if no one answers. To get notifications about the status of a call, include the status_callback parameter with your request. The full list of parameters that can be passed is available in the twilio-python helper library documentation.

When the call is complete, or if the line is busy or no one answers, Twilio will make a request to the URL you specify in the status_callback parameter.
