@sayuri-sam you need to use double curly braces {{currentAccessToken}}

Hi @anantyadunath. Quick question, did you ever get auth code flow working with Postman?

Hi, Do you have a solution if our authorization is with Grant Type: Authorization Code (with PKCE).
we don`t use client secret, and we put it blank.
I turn on Auto-refresh token and every API works great, but in monitor I get No response.
