Describe the question in detail

The Docs for the -*AuthKey don't mention the type of authentication to use, I know its by using a query arg like ?authKey= but today I forgot that and keep trying Basic Auth, encoding the key, or using Bearer tokens since not a single clue was in the docs, would be nice to include a text like: "For use in query arg: authKey="
Thanks.

Edit: the response could use too a more descriptime message, instead of "The provided authKey doesn't match -*AuthKey" -> "The provided query argument: authKey doesn't match -*AuthKey"
or if no auth key is provided
"Please provide a valid authKey arg in the query" or something.
