<p> The <code>DeleteHIT</code> operation is used to delete HIT that is no longer needed. Only the Requester who created the HIT can delete it. </p> <p> You can only dispose of HITs that are in the <code>Reviewable</code> state, with all of their submitted assignments already either approved or rejected. If you call the DeleteHIT operation on a HIT that is not in the <code>Reviewable</code> state (for example, that has not expired, or still has active assignments), or on a HIT that is Reviewable but without all of its submitted assignments already approved or rejected, the service will return an error. </p> <note> <ul> <li> <p> HITs are automatically disposed of after 120 days. </p> </li> <li> <p> After you dispose of a HIT, you can no longer approve the HIT's rejected assignments. </p> </li> <li> <p> Disposed HITs are not returned in results for the ListHITs operation. </p> </li> <li> <p> Disposing HITs can improve the performance of operations such as ListReviewableHITs and ListHITs. </p> </li> </ul> </note>
