This blog post demonstrates how to leverage Segment to capture and track progress through Studio Flows using Functions, specifically adapting a standard Appointment Reminder Studio Flow Template to track feedback in Segment. The process requires setting up a Twilio account with a phone number and a Segment account with Functions enabled, then configuring a test webhook from the Studio flow to confirm it is sending the right information across to Segment Functions. Once confirmed, the function can be replaced with custom code to track studio flow steps, including phone numbers, flow names, and stages as properties, and can be used to trigger escalations or build custom audiences based on responses. The integration allows for end-to-end tracking of studio flows and provides a foundation for more advanced use cases such as automated escalations or personalized SMS notifications.
