I am trying to perform Docusign authorization using Authorization Code Grant. I tested it via POSTMAN and it works fine but when I run via my APEX application, I get a "400 Bad Request" response from the request.
Attached file contains the function used.
obtain_access_token 2021-03-08.txt (2.12 KB)DB: Oracle 19c
APEX 19.1
Can someone please assist?
