Responding to SMS Text Messages with Python & Flask

Responding to SMS Text Messages with Python & Flask

A quick tutorial on receiving and responding to SMS text messages in a Flask application built with Python. Great post on!

Short Message Service (SMS) text messages are easy to send from Python applications with a web application programming interface (API). Flask applications can also receive incoming text messages and respond back to the sender with just a few lines of Python code.

Tools We Need

This tutorial is fine for both Python 2 and 3. Make sure you have one of those two versions installed on your system.

If you need assistance getting pip and virtualenv installed, take a look at the first few steps in the how to set up Python 3, Flask and Green Unicorn on Ubuntu 16.04 LTS guide, which shows how to install system packages for those tools.

Installing Our Dependencies

Our code will use a helper library to make it easier to respond to text messages from Python. The helper library dependency along with the Flask code library can be installed from PyPI into a virtualenv. In your terminal use the following command to generate a new virtualenv.

virtualenv respondsms

Activate the virtualenv.

source respondsms/bin/activate
