On Nintex 365, I really need to query a user using the value contained in the user profile Alias field. Any clues on how this could be done using JS or Jquery?

+6Right (my answer was for Nintex Workflow for Office 365).
The theory: User profiles REST API reference
In the next link, you have an example

Just a note about the example: it is for SP OnPrem. Replace the "_spPageContextInfo.webAbsoluteUrl" by a request on the querystring to get the "SPHostUrl".
