How to get OAuth2 access token with restclient.el or verb.el.

[removed]

Personally, I just run the source block with curl to get the token into the buffer, and then update a named scalar like: #+name: token : Bearer Blah blah blah....blah

you can create a function to do that then set a var using that function. e.g. :token := (any-lisp-code) GET https://example.com/foo/bar Authorization: :token
