This is a Twilio webhook, hosted on vercel as a serverless function. It works together with the nurse-button-diy project. Any replies to the "nurse button has been pressed" Twilio message will trigger this webhook. It will message all designated recipients, letting everyone know that someone has acted upon the nurse button event.
The Twilio webhook is configured on the Twilio Console https://console.twilio.com
