Welcome to the Python Starter!
This project is pre-configured to do some interesting Twilio stuff using Python and the Flask web framework.
Setting Up
We assume that before you begin, you will have Python and pip installed on your system and available at the command line.
Before you can run this project, you will need to set three system environment variables. These are:
TWILIO_ACCOUNT_SID: Your Twilio "account SID" - it's like your username for the Twilio API. This and the auth token (below) can be found on your account dashboard.TWILIO_AUTH_TOKEN: Your Twilio "auth token" - it's your password for the Twilio API. This and the account SID (above) can be found on your account dashboard.TWILIO_NUMBER: A Twilio number that you own, that can be used for making calls and sending messages. You can find a list of phone numbers you control (and buy another one, if necessary) in the account portal.
For Mac and Linux, environment variables can be set by opening a terminal window and typing the following three commands - replace all the characters after the = with values from your Twilio account:
export TWILIO_ACCOUNT_SID=ACXXXXXXXXX
export TWILIO_AUTH_TOKEN=XXXXXXXXX
export TWILIO_NUMBER=+16518675309
To make these changes persist for every new terminal (on OS X), you can edit the file ~/.bash_profile to contain the three commands above. This will set these environment variables for every subsequent session. Once you have edited the file to contain these commands, run source ~/.bash_profile in the terminal to set up these variables.
On Windows, the easiest way to set permanent environment variables (as of Windows 8) is using the setx command. Note that there is no =, just the key and value separated by a space:
setx TWILIO_ACCOUNT_SID ACXXXXXXXXX
setx TWILIO_AUTH_TOKEN XXXXXXXXX
setx TWILIO_NUMBER +16518675309
Running the application
Download the project source code directly or clone the repository on GitHub. Navigate to the folder with the source code on your machine in a terminal window.
You will first need to install the application's dependencies. To install them manually, type the following commands in your terminal:
pip install twilio
pip install flask
Now, you should be able to launch the application. From your terminal, run python app.py. This should launch your sinatra application on port 5000 - visit that URL on your local host. Enter your mobile number in the fields provided, and test both SMS text messages and phone calls being sent to the mobile number you provide.
