Passing org variables doesn't work

[AsterOps]

Hi, I try to pass variable from one source block to restclient source block, but it seems doesn't work.

#+name: auth
#+begin_src emacs-lisp
(base64-encode-string "test:123456")
#+end_src

#+RESULTS: auth
: dGVzdDoxMjM0NTY=

#+begin_src restclient :var VAR=auth
  GET http://localhost:8080/some-endpoint
  Authorization: Basic $VAR
#+end_src

#+RESULTS:
#+BEGIN_SRC js
// GET http://localhost:8080/some-endpoint
// HTTP/1.1 401 Unauthorized
...
#+END_SRC

When I wirte straightforward basic auth it works

#+begin_src restclient
  GET http://localhost:8080/some-endpoint
  Authorization: Basic dGVzdDoxMjM0NTY=
#+end_src

#+RESULTS:
#+BEGIN_SRC js
[
  "some-content"
]

// GET http://localhost:8080/some-endpoint
// HTTP/1.1 200
...
#+END_SRC

When I try to simply print this variable in shell it's work

#+begin_src sh :var VAR=auth
echo $VAR
#+end_src

#+RESULTS:
: dGVzdDoxMjM0NTY=

I tried also with different types of results (raw etc.) but the effect was the same. Is it something I do wrong or maybe is it some workaround? Thx

ob-restclient passes variables as-is into restclient, so you have to refer to them via :, e.g.:

#+begin_src restclient :var auth=auth
PUT http://my-service.io
Authorization: Bearer :auth
#+end_src

As @Patryk27 says, variables in restclient are prefixed by : and not $.

I guess the problem here is our almost complete lack of documentation.
