// The CreateHIT operation creates a new Human Intelligence Task (HIT). The new
// HIT is made available for Workers to find and accept on the Amazon Mechanical
// Turk website. This operation allows you to specify a new HIT by passing in
// values for the properties of the HIT, such as its title, reward amount and
// number of assignments. When you pass these values to CreateHIT , a new HIT is
// created for you, with a new HITTypeID . The HITTypeID can be used to create
// additional HITs in the future without needing to specify common parameters such
// as the title, description and reward amount each time. An alternative way to
// create HITs is to first generate a HITTypeID using the CreateHITType operation
// and then call the CreateHITWithHITType operation. This is the recommended best
// practice for Requesters who are creating large numbers of HITs. CreateHIT also
// supports several ways to provide question data: by providing a value for the
// Question parameter that fully specifies the contents of the HIT, or by providing
// a HitLayoutId and associated HitLayoutParameters . If a HIT is created with 10
// or more maximum assignments, there is an additional fee. For more information,
// see Amazon Mechanical Turk Pricing (https://requester.mturk.com/pricing) .

	// Question parameter or a HITLayoutId parameter must be provided.
	Question *string

	// An arbitrary data field. The RequesterAnnotation parameter lets your
	// application attach arbitrary data to the HIT for tracking purposes. For example,
	// this parameter could be an identifier internal to the Requester's application
	// that corresponds with the HIT. The RequesterAnnotation parameter for a HIT is
	// only visible to the Requester who created the HIT. It is not shown to the
	// Worker, or any other Requester. The RequesterAnnotation parameter may be
	// different for each HIT you submit. It does not affect how your HITs are grouped.
	RequesterAnnotation *string

	// A unique identifier for this request which allows you to retry the call on
	// error without creating duplicate HITs. This is useful in cases such as network
	// timeouts where it is unclear whether or not the call succeeded on the server. If
	// the HIT already exists in the system from a previous call using the same
	// UniqueRequestToken, subsequent calls will return a
	// AWS.MechanicalTurk.HitAlreadyExists error with a message containing the HITId.
