When getting data from web, the option to select Authorization as a header seems to be missing. Is there anyway to get it to appear again or work around this issue?
You can update to the latest version of Power BI Desktop to see if the problem exists, I browsed past posts with similar experiences to yours, you need to do the Web import "manually" by opening a blank query. For the original Post , you can see REST API (web data source) Authentication Header is gone
