OAuth2 - server to server

Hi folks,

I'd like to create an API connection wtih my LightRoom portfolio. I would like to programmatically do queries via Postman, and this is not about building an app. It's strictly doing so via APIs.

I'm not able to generate tokens that I can then use as part of my API calls. Does Lightroom support this, or does it only support webapp Oauth for Lightroom?

Thanks
