Auth Code request URL is mandatory to set up OAuth 2.0 Authentication in web service

Hi Community,

I want to make use of and set up OAuth 2.0 Authentication in web service authentication. For that I found below the academy article :

https://academy.creatio.com/docs/user/no_code_customization/web_service…

While setting up as per the article, there is one required field in the OAuth Setting fields which is "Auth code request URL".

But the API endpoints for which, I have to make use of Web Service OAuth Authentication, is not having settings for Auth code request URL required parameter.

Please guide and help me on this point that how I can set up OAuth Authentication in web service without Auth code request URL.
