Fetch Oauth 2.0 token for Authorisation Code Flow

Question

I can trying to fetch the oauth2 token from token url .I am using authorisation code flow in Oauth2 . For the token url call ,mandatory parameter is code. So I need to do a get call on authorization url and get the code. In postman while doing the authorization call I am getting redirect page(ui to enter credentials) .Is there any other way to fetch the token using this flow without going through ui as this is specifically testing api This is for API Automation Testing.

Microsoft documentation attached - https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow

Answer 1

It is not easy in OAuth to get a token for a user for automated test scenarios. Authorization Code Flow requires redirects to be followed and complex slow code

Usually you do not want to test Azure AD itself because it is not your code.

One simpler option for automated tests is to use Resource Owner Password Grant to get a token as a user via a simple HTTPS POST. It is not recommended to use this in real UIs though.
