PAM http module to allow login with an http request

I'm working on a project to make a system to manage, create and start debian image for lab exam of my university (with PXE). I have to make a PAM module to allow login with the credentials generated by my system. I would like to make login with a simple http request with username and password. I found a project on Github called pam-http but this module allows login with only userID. How I can make it? Thank you for any advice!
