Hi @v-polly-msft ,
I tried the solution you provided from the links, but did not work for my scenario. I need to access to a API with a dynamic access token which need to be refreshed every one hour. The access token is part of the header.
if I put the authorization part in a query, the authentication did not work.
it works using header, but it won't allow me to refresh in Power Bi service using this way.
