How do you do authentication with url.el?

How do you do authentication with url.el?

I'm trying to  communicate with a Restful api using url.el. When it comes
to authentication, their documentation simply says to call curl with "-u
user:password".

What is the url equivalent of that option in curl? That is, how do I
replicate the following command with url-retrieve-synchronously?
    curl -u user:password https://gnu.org

Does something like 'https://username:password@domain' work?

Actually no, sorry. It doesn't work.
url-retrieve-synchronously still asks me for a user/password
combination even if I write it like that.

It appeared to work before because url was using some cache of a
previous authentication.

Just to clarify what's happening. Running this command succeeds immediately:
      curl -X PUT
https://USER:TOKEN@api.github.com/user/starred/Malabarba/EndlessParentheses

But evaluating this asks me for a user/password combination:
    (let ((url-request-method "PUT"))
      (url-retrieve-synchronously
"https://USER:TOKEN@api.github.com/user/starred/Malabarba/EndlessParentheses"))

This should work:

(let ((url-request-method "PUT")
      (url-request-extra-headers 
          `(("Authorization" . ,(concat "Basic "
                                        (base64-encode-string
                                         "user:token"))))))
  (url-retrieve-synchronously
"https://api.github.com/user/starred/Malabarba/EndlessParentheses"))

Left you a star ;)
