Hello
I have a .org file where I am using sh code blocks to interact with a REST
API via curl. My first call is to authenticate with the REST API which
returns a token in the HTTP response. I would like to parse that HTTP
response (ie. with elisp via a subsequent code block) and use the token in
subsequent sh code blocks.
Right now I am doing this via a manual step where I step where I run the
first sh code block, set a :var PROPERTY, and then run the rest of the sh
code blocks. I would like to automate it if possible.
Thanks,
-Rehan

Would something like the following work?

It is possible to chain code blocks in variable lines as shown, see the
manual pages on the :var and potentially also the :post header
arguments. Also, the following has multiple examples demonstrating this
sort of usage.

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
