Container for the parameters to the CreateHITWithHITType operation. The CreateHITWithHITType operation creates a new Human Intelligence Task (HIT) using an existing HITTypeID generated by the CreateHITType operation.

This is an alternative way to create HITs from the CreateHIT operation. This is the recommended best practice for Requesters who are creating large numbers of HITs.

CreateHITWithHITType 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.

The CreateHITWithHITTypeRequest type exposes the following members

Constructors

Properties

NameTypeDescription
Public Property AssignmentReviewPolicy Amazon.MTurk.Model.ReviewPolicy

Gets and sets the property AssignmentReviewPolicy.

The Assignment-level Review Policy applies to the assignments under the HIT. You can specify for Mechanical Turk to take various actions based on the policy.

Public Property HITLayoutId System.String

Gets and sets the property HITLayoutId.

The HITLayoutId allows you to use a pre-existing HIT design with placeholder values and create an additional HIT by providing those values as HITLayoutParameters.

Constraints: Either a Question parameter or a HITLayoutId parameter must be provided.

Public Property HITLayoutParameters System.Collections.Generic.List<Amazon.MTurk.Model.HITLayoutParameter>

Gets and sets the property HITLayoutParameters.

If the HITLayoutId is provided, any placeholder values must be filled in with values using the HITLayoutParameter structure. For more information, see HITLayout.

Public Property HITReviewPolicy Amazon.MTurk.Model.ReviewPolicy

Gets and sets the property HITReviewPolicy.

The HIT-level Review Policy applies to the HIT. You can specify for Mechanical Turk to take various actions based on the policy.

Public Property HITTypeId System.String

Gets and sets the property HITTypeId.

The HIT type ID you want to create this HIT with.

Public Property LifetimeInSeconds System.Int64

Gets and sets the property LifetimeInSeconds.

An amount of time, in seconds, after which the HIT is no longer available for users to accept. After the lifetime of the HIT elapses, the HIT no longer appears in HIT searches, even if not all of the assignments for the HIT have been accepted.

Public Property MaxAssignments System.Int32

Gets and sets the property MaxAssignments.

The number of times the HIT can be accepted and completed before the HIT becomes unavailable.

Public Property Question System.String

Gets and sets the property Question.

The data the person completing the HIT uses to produce the results.

Constraints: Must be a QuestionForm data structure, an ExternalQuestion data structure, or an HTMLQuestion data structure. The XML question data must not be larger than 64 kilobytes (65,535 bytes) in size, including whitespace.

Either a Question parameter or a HITLayoutId parameter must be provided.

Public Property RequesterAnnotation System.String

Gets and sets the property RequesterAnnotation.

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.

Public Property UniqueRequestToken System.String

Gets and sets the property UniqueRequestToken.

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.

Note: It is your responsibility to ensure uniqueness of the token. The unique token expires after 24 hours. Subsequent calls using the same UniqueRequestToken made after the 24 hour limit could create duplicate HITs.
