Glitch developed an "Ask Mindy Anything" app that lets hosts solicit live questions from the audience, showcasing Twilio APIs during a SIGNAL 2019 interview. The app uses Twilio's Programmable SMS service to handle incoming questions and includes a form on the landing page for users without roaming plans. The back end of the app consists of an Express server in Node.js, which handles secure HTTPS connections and sets up endpoints for fetching and manipulating submitted questions. The app also has a human curation element to control for abuse, presenting a curated subset of questions to the interviewer during the live event.
