I am in need of calling a rest service that requires an oauth token. My requirements are that we use grant_type=client_credentials as well as specifying the scope. I don't see a way to make these adjustments via the UI. If I try leaving out Username/Password fields which are optional according to the documentation, I receive the error
"The OAuth URL, User name, Password, OAuth Client ID and OAuth Cleint Secret should be configured/provided when OAuth is selected and OAuth token is not provided."
However if I supply dummy values for those fields, it looks like it tries to use grant_type=password.
