SMS Usage Alerts for your Twilio Account with Python and Flask

This tutorial guides developers in setting up an SMS usage alert system using Python, Flask, and the Twilio API. To start, they need to create a new Flask project, install necessary dependencies, configure their Twilio account credentials, and set up a Flask application with a /usage-alert endpoint that sends an SMS notification when a certain threshold is reached. Next, they need to create a usage trigger in the Twilio Console that invokes this endpoint, which can be done by setting up a low threshold for voice calls. The tutorial concludes with testing the trigger and verifying its functionality.
