I have a similar setup, using snare to handle the webhook endpoint: https://github.com/softdevteam/snare

GitHub will call the webhook after a push to main and a successful test suite run. Snare runs a shell script on my server to git pull, build, deploy, and call a cronitor.io hook for monitoring deploy success.

I've been pretty happy with how relatively simple it is and how well it works.
