NGINX and REST API

[Dunkstormen]

Anyone having some experience with NGINX and can help me setting up my API location, so I can pass the API Token using headers rather than as a part of the URL?

Have been looking on sites like Stackoverflow for a potential solution, yet none of the suggestions has worked.

The exact message I get is the one on the attached image.
