There is a website layout in JS similar to the virtual systems manager, how to implement its connection with the Proxmox virtualization server?

Question

Web development

I would like to implement a site with a choice of operating systems and programs, where after authorization people filed either an application, or if the task was easy, then the virtualization server could automatically open the template with a ready-made assembly of the necessary software. The button from the web interface should send a command to the server, parsing which the "server" should understand which virtual machine and with which OS it needs to create. This is necessary for people who do not have special administration and visualization skills. I know that Proxmox has its own API, but I have never worked with the API. Can you tell me in which direction to dig or already a person who did such a task.
Implementation of the site in JS. CSS.
