Working with rest api calls (sevone nms and grafana)

I’m new to grafana and am trying to get metrics from a sevone nms server via rest api into grafana. the challenge i’m running into is in order to GET the endpoint from sevone there has to be some sort of authorization to be able to pull the particular endpoint details on the sevone nms side. The recommendation is to create an application token on sevone server but i don’t see a way to be able to utilize that token on the grafana side.

has anyone ever successfully implemented between these 2 systems? or can someone offer some advice on how to achieve what i’m trying to do?
