I am trying to Authorize via OAuth with Trello and I can't seem to get it right, even in postman.
I have followed their API docs and have got myself a developer key and I have used a little link they have in this article to get a valid auth token.
I tried including the API key and Auth token in the header and (in a separate test) in the body, as per their documentation.

Everything I try results in "unauthorized permission requested". What am I doing wrong?
