Functions

The AcceptQualificationRequest operation approves a Worker's request for a Qualification.

Only the owner of the Qualification type can grant a Qualification request for that type.

The ApproveAssignment operation approves the results of a completed assignment.

Approving an assignment initiates two payments from the Requester's Amazon.com account

• The Worker who submitted the results is paid the reward specified in the HIT.

• Amazon Mechanical Turk fees are debited.

If the Requester's account does not have adequate funds for these payments, the call to ApproveAssignment returns an exception, and the approval is not processed. You can include an optional feedback message with the approval, which the Worker can see in the Status section of the web site.

The AssociateQualificationWithWorker operation gives a Worker a Qualification.

AssociateQualificationWithWorker does not require that the Worker submit a Qualification request. It gives the Qualification directly to the Worker.

You can only assign a Qualification of a Qualification type that you created (using the CreateQualificationType operation).

The CreateAdditionalAssignmentsForHIT operation increases the maximum number of assignments of an existing HIT.

To extend the maximum number of assignments, specify the number of additional assignments.

HITs created with fewer than 10 assignments cannot be extended to have 10 or more assignments. Attempting to add assignments in a way that brings the total number of assignments for a HIT from fewer than 10 assignments to 10 or more assignments will result in an AWS.MechanicalTurk.InvalidMaximumAssignmentsIncrease exception.

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.

The CreateHITType operation creates a new HIT type.

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.

The CreateQualificationType operation creates a new Qualification type, which is represented by a QualificationType data structure.

The CreateWorkerBlock operation allows you to prevent a Worker from working on your HITs.

The DeleteHIT operation is used to delete HIT that is no longer needed.

Only the Requester who created the HIT can delete it.

You can only dispose of HITs that are in the Reviewable 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 Reviewable 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.

HITs are automatically disposed of after 120 days.

After you dispose of a HIT, you can no longer approve the HIT's rejected assignments.

Disposed HITs are not returned in results for the ListHITs operation.

The DeleteQualificationType deletes a Qualification type and deletes any HIT types that are associated with the Qualification type.

This operation does not revoke Qualifications already assigned to Workers because the Qualifications might be needed for active HITs. If there are any pending requests for the Qualification type, Amazon Mechanical Turk rejects those requests. After you delete a Qualification type, you can no longer use it to create HITs or HIT types.

The DeleteWorkerBlock operation allows you to reinstate a blocked Worker to work on your HITs.

The DisassociateQualificationFromWorker revokes a previously granted Qualification from a user.

The GetAccountBalance operation retrieves the amount of money in your Amazon Mechanical Turk account.

The GetAssignment operation retrieves the details of the specified Assignment.

The GetFileUploadURL operation generates and returns a temporary URL.

The GetHIT operation retrieves the details of the specified HIT.

The GetQualificationScore operation returns the value of a Worker's Qualification for a given Qualification type.

To get a Worker's Qualification, you must know the Worker's ID. The Worker's ID is included in the assignment data returned by the ListAssignmentsForHIT operation.

The GetQualificationTypeoperation retrieves information about a Qualification type using its ID.

The ListAssignmentsForHIT operation retrieves completed assignments for a HIT.

You can use this operation to retrieve the results for a HIT.

You can get assignments for a HIT at any time, even if the HIT is not yet Reviewable. If a HIT requested multiple assignments, and has received some results but has not yet become Reviewable, you can still retrieve the partial results with this operation.

Use the AssignmentStatus parameter to control which set of assignments for a HIT are returned. The ListAssignmentsForHIT operation can return submitted assignments awaiting approval, or it can return assignments that have already been approved or rejected. You can set AssignmentStatus=Approved,Rejected to get assignments that have already been approved and rejected together in one result set.

Only the Requester who created the HIT can retrieve the assignments for that HIT.

The ListBonusPayments operation retrieves the amounts of bonuses you have paid to Workers for a given HIT or assignment.

The ListHITs operation returns all of a Requester's HITs.

The ListHITsForQualificationType operation returns the HITs that use the given Qualification type for a Qualification requirement.

The ListQualificationRequests operation retrieves requests for Qualifications of a particular Qualification type.

The ListQualificationTypes operation returns a list of Qualification types, filtered by an optional search term.

The ListReviewPolicyResultsForHIT operation retrieves the computed results and the actions taken in the course of executing your Review Policies for a given HIT.

The ListReviewableHITs operation retrieves the HITs with Status equal to Reviewable or Status equal to Reviewing that belong to the Requester calling the operation.

The ListWorkersBlocks operation retrieves a list of Workers who are blocked from working on your HITs.

The ListWorkersWithQualificationType operation returns all of the Workers that have been associated with a given Qualification type.

The NotifyWorkers operation sends an email to one or more Workers that you specify with the Worker ID.

The RejectAssignment operation rejects the results of a completed assignment.

You can include an optional feedback message with the rejection, which the Worker can see in the Status section of the web site. When you include a feedback message with the rejection, it helps the Worker understand why the assignment was rejected, and can improve the quality of the results the Worker submits in the future.

The RejectQualificationRequest operation rejects a user's request for a Qualification.

The SendBonus operation issues a payment of money from your account to a Worker.

The SendTestEventNotification operation causes Amazon Mechanical Turk to send a notification message as if a HIT event occurred, according to the provided notification specification.

The UpdateExpirationForHIT operation allows you update the expiration time of a HIT.

The UpdateHITReviewStatus operation updates the status of a HIT.

The UpdateHITTypeOfHIT operation allows you to change the HITType properties of a HIT.

The UpdateNotificationSettings operation creates, updates, disables or re-enables notifications for a HIT type.

The UpdateQualificationType operation modifies the attributes of an existing Qualification type, which is represented by a QualificationType data structure.

Only the owner of a Qualification type can modify its attributes.

Most attributes of a Qualification type can be changed after the type has been created. However, the Name and Keywords fields cannot be modified. The RetryDelayInSeconds parameter can be modified or added to change the delay or to enable retries, but RetryDelayInSeconds cannot be used to disable retries.

You can use this operation to update the test for a Qualification type. The test is updated based on the values specified for the Test, TestDurationInSeconds and AnswerKey parameters. All three parameters specify the updated test. If you are updating the test for a type, you must specify the Test and TestDurationInSeconds parameters. The AnswerKey parameter is optional; omitting it specifies that the updated test does not have an answer key.

If you omit the Test parameter, the test for the Qualification type is unchanged. There is no way to remove a test from a Qualification type that has one. If the type already has a test, you cannot update it to be AutoGranted. If the Qualification type does not have a test and one is provided by an update, the type will henceforth have a test.

If you want to update the test duration or answer key for an existing test without changing the questions, you must specify a Test parameter with the original questions, along with the updated values.

If you provide an updated Test but no AnswerKey, the new test will not have an answer key. Requests for such Qualifications must be granted manually.
