This tutorial provides an overview of how to send scheduled SMS notifications using the Twilio Programmable Messaging service and the Go programming language. The tutorial assumes that the reader has a basic understanding of Go and Twilio, and guides them through the process of creating a new Go project, configuring a Twilio account, and sending a scheduled SMS. The application uses environment variables to store Twilio account credentials and messaging service SID, which are then used to authenticate with the Twilio API and schedule an SMS. Once the SMS is scheduled, the application prints the message ID to the terminal, and the reader must wait for 61 minutes before receiving the SMS on their phone. The tutorial concludes by providing additional resources for further learning on scheduling SMS and message scheduling FAQs and beta limitations.
