This tutorial teaches users how to create custom reports using the Twilio REST API in Python, Pandas, and Jupyter Notebooks. To start, users need a free or paid Twilio account with activity history, a Python virtual environment, and necessary dependencies installed, including jupyter, requests, python-dotenv, pandas, and matplotlib. The tutorial guides users through setting up a Jupyter Notebook, storing Twilio credentials as environment variables, making API requests to retrieve SMS messages, transforming the data into a DataFrame, and displaying it in various formats, such as a bar graph. Once the notebook is complete, users can share their findings with others by adding documentation, sharing the virtual environment, saving to version control securely, and rendering the notebook as a static HTML web page or running it interactively on a notebook server or cloud options like Binder.
