google-apis-explorer fails to put valid API key in URL POST request

What steps will reproduce the problem?
1. Open the Google Maps Engine API tutorial on "Getting Your Data on a Map" 
with the following URL:
2. 
https://developers.google.com/maps-engine/documentation/tutorial-create-map#auth
3. Replace "{projectId}" with a valid project ID, and hit 'Execute'.

We're supposed to get a valid response from mapsengine.tables.upload. Instead, 
I see:

>>>>>> OUTPUT COPIED FROM HERE >>>>>
POST https://www.googleapis.com/mapsengine/v1/tables/upload?key={YOUR_API_KEY}

  "population growth",
  "population change"

  "primaryKey": "COUNTRY"
 }
}

****Note the {YOUR_API_KEY} is not replaced with my valid API key.****

There is no place to input my API KEY, so I have to assume the 
google-apis-explorer is expected to fill it in automatically.
