Details
An ExternalQuestion is a HIT stored anywhere other than the MTurk server that is displayed to workers within an HTML iframe of the specified height. The URL should point to a page --- likely an HTML form --- that can retrieve several URL GET parameters for “AssignmentId” and “WorkerId”, which are attached by MTurk when opening the URL. The page should also be able to submit those parameters plus any assignment data to https://www.mturk.com/mturk/externalSubmit using either the HTTP GET or POST methods.
