This tutorial explains how to configure a proxy number with delivery instructions using Twilio's no-code solution, Twilio Studio. A proxy number is used to provide personal information to delivery drivers without sharing one's personal phone number. The process involves creating a flow in Twilio Studio that handles incoming messages and calls from the driver, providing gate codes, directions, and call forwarding options. The tutorial covers setting up a menu system, handling different conditions, and integrating call forwarding with the proxy number. By following this guide, users can create a secure and convenient way to communicate with delivery drivers while maintaining their personal information private.
