I have setup a web hooks with www.losant.com/ and added a web hook too zoom when instructed to turn off/on when a meeting is created or ended and this controls a esp8266 with a solid state relay and a LED bulb. Wi-Fi connected and no Pi needed.
For the Pi you could try something like this …
Enable Web hooks on Zoom after setting up a Start and Stop Web hook and workflows on losant for both…
If you have any questions let me know I am just a hacker and by no means a programmer.
