There has got to be something simple I am missing but your help is appreciated as I am very new to this.
I am trying to setup API Key authentication. I entered some basic info but didn’t change too much…
When I test it I get the error below and can’t figure out why…
Hi 
From that error, it sounds like the API key hasn’t been provided before testing the authentication - you’ll want to make sure you have popups enabled so that you get the screen to input that API key into, if that is what your app needs to authenticate
