I was wondering if anyone knows if this would be the correct approach for going about this process.
I am making a VPN service as a project to further my computer programming background and portfolio.
I was wondering, after a successful verification purchase for a VPN subscription on www.example.com, would the correct route to auto create the subscribers VPN account be to:
Fire off a .sh (shell script) hosted on the server with PHP variables passed to the script for the $username & $password. Which in return will run on the server and create the subscribers access account.
