Pritunl API documentation

I suppose list of API endpoints should be accessible here - https://pritunl.com/api.html, but it returns 404. https://docs.pritunl.com/reference also shows nothing
Where can I find API documentation please?

There’s never been a list of API endpoints, Google Chrome Developer Tools can be used to find the API functions. There is an example of the API usage in pritunl/tools/add_aws_ranges.py.
