title: How to specify an API key name in Excel - A web API key can only be specified when a web API key name is provided
body: <p>I have a standard <code>MVC API OData enabled service</code> which works under anonymous authentication. I would like to pass a web API key to the application...which works fine when added through code or postman..</p>
  
  <p>Unfortunately my users would prefer to use <code>Excel</code> and I can't I find anywhere in Excel to enter this data...</p>
  
  <p>I've checked <code>Fiddler</code> and  <code>Excel</code> is not even trying to send data to the client and I am trapped in one of the errors below. </p>
  
  <p>What is a valid key in Excel and how do it enter it?</p>
