This is a server that serves the simple purpose of transmitting information from Authentic Insurance's customer.io policy sold flow to the microcontroller for the Policy Alarm (POLAR) v2.

Arduino microcontrollers (like the WT32-ETH01 board used) cannot act as a web server without adding port forwarding settings. This server gets around that by exposing whether or not a policy was sold in the last 5 seconds to the web (POST on /customer), which the microcontroller GETs (on /beacon).
