I am not sure, if I understand your question correctly. But passing the
token to another code block is easy.
There are two straight forwards ways:
1. As a variable
--8<---------------cut here---------------start------------->8---
#+name: authenticate
#+begin_src sh
## do sth to generate a token
token="uagpb"
echo "$token"
#+end_src
#+name: usethetoken
#+header: :var token=authenticate()
#+begin_src sh
echo "${token}.ext"
#+end_src
#+results: usethetoken
: uagpb.ext
--8<---------------cut here---------------end--------------->8---
2. Using noweb
--8<---------------cut here---------------start------------->8---
#+name: authenticate
#+begin_src sh
## do sth to generate a token
token="uagpb"
echo "$token"
#+end_src
#+name: usethetokenvianoweb
#+begin_src sh :noweb yes
token=<<authenticate()>>
echo "${token}.ext"
#+end_src
#+results: usethetokenvianoweb
: uagpb.ext
--8<---------------cut here---------------end--------------->8---
HTH,
Andreas
