Hi @larshp I have created a Oauth Client in ABAP which retrieves bearer tokens and refresh tokens from AZURE AD. Since our Azure Devops VSTS Repos are protected we have to authenticate each connection call. Our organization don't want to create PAT to login and they want to use SSO for that. Here comes the use of Oauth client, Can you please point me where can i modify the code, so that instead of asking user id and paswword, abapGit should set the token in http_client call and directly makes call with bearer tokens. Also if bearer token fails then i should be able to use refresh_flow to get new token with refresh token.

above code is for SAP reentrance tickets, not related to oauth, I don't have experience setting up oauth
