Conection between chrome extension and django website

I am developing a Chrome extension that detect when a file is dowloaded, send it to a website (also created by me with Django) and after the website processed it, Chrome extension receives another file with some results.

I would like to know how I could connect them. Does someone have any example or name of some technology that allows Chrome extension send and receive files from a website or server? Thank you in advance!
