To record page visits to a Flask website with Twilio Segment, create a Segment source that submits page view events from the Python web server. This approach allows for full control over data sharing and eliminates the need for third-party analytics libraries in the front end. The solution involves installing the Segment library for Python, configuring the write key assigned to the Python Server source, and adding an analytics destination such as Mixpanel or Google Analytics 4. Once configured, page view events are sent to the chosen analytics service, where they can be visualized in real-time using a dashboard or reports. This approach provides a private and anonymous way to track website traffic, making it suitable for applications that require compliance with online privacy regulations.
