Auto Create User Account Script in WHM/cPanel

I need a script that would auto create a user account in WHM/cPanel automatically based on the selected packages already created in WHM/cPanel with SECURITY in mind. *Most use WHM/cPanel MANAGED API TOKEN. *Auto create selected customer package on the script. *The script will auto-identify the paid package to be created in WHM cPanel. *Must not trigger WHM cPanel SECURITY issues or problems. *Must have security measures from auto bots etc.. *Please let me know if you can do this in 2 days. ***NO ACCESS TO WORDPRESS OR SERVER the script or plugin is all done on your side and I just need to install. BACKEND Basically, it's kind of script or wp plugin where you input TOKEN API and identified all the packages created and save settings for cPanel user creation. FRONTEND Customer click on selected package pay with stripe then on the thank you page (we will just give thank you URL to that product) it will direct the customer to create their cPanel user account or an email will be sent to create the cPanel user account. Any other ways or suggestions on implementing cPanel user creation after the customer pays would be appreciated.
