The RejectAssignment operation rejects
the results of a completed assignment.
Rejecting an assignment indicates that the Requester believes the results submitted by the Worker do not properly answer the question described by the HIT. The Worker is not paid for a rejected assignment.
Rejecting an assignment does not affect the number of
assignments available to other Workers. To make another
assignment available for a HIT, use the
ExtendHIT operation. Because a Worker may
only accept a HIT once, the Worker who submitted the rejected
results will not be allowed to accept the HIT again.
You can include an optional feedback message with the rejection, which the Worker can see in the "status" section of the web site. Including a feedback message with the rejection can help the Worker understand why the assignment was rejected, and can improve the quality of the results the Worker submits in the future.
