Container for the parameters to the AcceptQualificationRequest operation. 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. A successful request for the AcceptQualificationRequest operation returns with no errors and an empty body.

Gets and sets the property IntegerValue. The value of the Qualification. You can omit this value if you are using the presence or absence of the Qualification as the basis for a HIT requirement.

Gets and sets the property QualificationRequestId. The ID of the Qualification request, as returned by the GetQualificationRequests operation.

This is the response object from the AcceptQualificationRequest operation.

Container for the parameters to the ApproveAssignment operation. 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. You can also call this operation for assignments that were previous rejected and approve them by explicitly overriding the previous rejection. This only works on rejected assignments that were submitted within the previous 30 days and only if the assignment's related HIT has not been deleted.

Gets and sets the property AssignmentId. The ID of the assignment. The assignment must correspond to a HIT created by the Requester.

Gets and sets the property OverrideRejection. A flag indicating that an assignment should be approved even if it was previously rejected. Defaults to False.

Gets and sets the property RequesterFeedback. A message for the Worker, which the Worker can see in the Status section of the web site.

This is the response object from the ApproveAssignment operation.

The Assignment data structure represents a single assignment of a HIT to a Worker. The assignment tracks the Worker's efforts to complete the HIT, and contains the results for later retrieval.

Gets and sets the property AcceptTime. The date and time the Worker accepted the assignment.

Gets and sets the property Answer. The Worker's answers submitted for the HIT contained in a QuestionFormAnswers document, if the Worker provides an answer. If the Worker does not provide any answers, Answer may contain a QuestionFormAnswers document, or Answer may be empty.

Gets and sets the property ApprovalTime. If the Worker has submitted results and the Requester has approved the results, ApprovalTime is the date and time the Requester approved the results. This value is omitted from the assignment if the Requester has not yet approved the results.

Gets and sets the property AssignmentId. A unique identifier for the assignment.

Gets and sets the property AssignmentStatus. The status of the assignment.

Gets and sets the property AutoApprovalTime. If results have been submitted, AutoApprovalTime is the date and time the results of the assignment results are considered Approved automatically if they have not already been explicitly approved or rejected by the Requester. This value is derived from the auto-approval delay specified by the Requester in the HIT. This value is omitted from the assignment if the Worker has not yet submitted results.

Gets and sets the property Deadline. The date and time of the deadline for the assignment. This value is derived from the deadline specification for the HIT and the date and time the Worker accepted the HIT.

Gets and sets the property HITId. The ID of the HIT.

Gets and sets the property RejectionTime. If the Worker has submitted results and the Requester has rejected the results, RejectionTime is the date and time the Requester rejected the results.

Gets and sets the property RequesterFeedback. The feedback string included with the call to the ApproveAssignment operation or the RejectAssignment operation, if the Requester approved or rejected the assignment and specified feedback.

Gets and sets the property SubmitTime. If the Worker has submitted results, SubmitTime is the date and time the assignment was submitted. This value is omitted from the assignment if the Worker has not yet submitted results.

Gets and sets the property WorkerId. The ID of the Worker who accepted the HIT.

Container for the parameters to the AssociateQualificationWithWorker operation. 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). Note: AssociateQualificationWithWorker does not affect any pending Qualification requests for the Qualification by the Worker. If you assign a Qualification to a Worker, then later grant a Qualification request made by the Worker, the granting of the request may modify the Qualification score. To resolve a pending Qualification request without affecting the Qualification the Worker already has, reject the request with the RejectQualificationRequest operation.

Gets and sets the property IntegerValue. The value of the Qualification to assign.

Gets and sets the property QualificationTypeId. The ID of the Qualification type to use for the assigned Qualification.

Gets and sets the property SendNotification. Specifies whether to send a notification email message to the Worker saying that the qualification was assigned to the Worker. Note: this is true by default.

Gets and sets the property WorkerId. The ID of the Worker to whom the Qualification is being assigned. Worker IDs are included with submitted HIT assignments and Qualification requests.

This is the response object from the AssociateQualificationWithWorker operation.

An object representing a Bonus payment paid to a Worker.

Gets and sets the property AssignmentId. The ID of the assignment associated with this bonus payment.

Gets and sets the property BonusAmount.

Gets and sets the property GrantTime. The date and time of when the bonus was granted.

Gets and sets the property Reason. The Reason text given when the bonus was granted, if any.

Gets and sets the property WorkerId. The ID of the Worker to whom the bonus was paid.

Container for the parameters to the CreateAdditionalAssignmentsForHIT 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.
HITs that were created before July 22, 2015 cannot be extended. Attempting to extend HITs that were created before July 22, 2015 will result in an AWS.MechanicalTurk.HITTooOldForExtension exception.

Gets and sets the property HITId. The ID of the HIT to extend.

Gets and sets the property NumberOfAdditionalAssignments. The number of additional assignments to request for this HIT.

Gets and sets the property UniqueRequestToken. A unique identifier for this request, which allows you to retry the call on error without extending the HIT multiple times. This is useful in cases such as network timeouts where it is unclear whether or not the call succeeded on the server. If the extend HIT already exists in the system from a previous call using the same UniqueRequestToken, subsequent calls will return an error with a message containing the request ID.

This is the response object from the CreateAdditionalAssignmentsForHIT operation.

Container for the parameters to the CreateHIT operation. 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.

Gets and sets the property AssignmentDurationInSeconds. The amount of time, in seconds, that a Worker has to complete the HIT after accepting it. If a Worker does not complete the assignment within the specified duration, the assignment is considered abandoned. If the HIT is still active (that is, its lifetime has not elapsed), the assignment becomes available for other users to find and accept.

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.

Gets and sets the property AutoApprovalDelayInSeconds. The number of seconds after an assignment for the HIT has been submitted, after which the assignment is considered Approved automatically unless the Requester explicitly rejects it.

Gets and sets the property Description. A general description of the HIT. A description includes detailed information about the kind of task the HIT contains. On the Amazon Mechanical Turk web site, the HIT description appears in the expanded view of search results, and in the HIT and assignment screens. A good description gives the user enough information to evaluate the HIT before accepting it.

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.

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.

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.

Gets and sets the property Keywords. One or more words or phrases that describe the HIT, separated by commas. These words are used in searches to find HITs.

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.

Gets and sets the property MaxAssignments. The number of times the HIT can be accepted and completed before the HIT becomes unavailable.

Gets and sets the property QualificationRequirements. Conditions that a Worker's Qualifications must meet in order to accept the HIT. A HIT can have between zero and ten Qualification requirements. All requirements must be met in order for a Worker to accept the HIT. Additionally, other actions can be restricted using the ActionsGuarded field on each QualificationRequirement structure.

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.

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.

Gets and sets the property Reward. The amount of money the Requester will pay a Worker for successfully completing the HIT.

Gets and sets the property Title. The title of the HIT. A title should be short and descriptive about the kind of task the HIT contains. On the Amazon Mechanical Turk web site, the HIT title appears in search results, and everywhere the HIT is mentioned.

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.

This is the response object from the CreateHIT operation.

Gets and sets the property HIT. Contains the newly created HIT data. For a description of the HIT data structure as it appears in responses, see the HIT Data Structure documentation.

Container for the parameters to the CreateHITType operation. The CreateHITType operation creates a new HIT type. This operation allows you to define a standard set of HIT properties to use when creating HITs. If you register a HIT type with values that match an existing HIT type, the HIT type ID of the existing type will be returned.

Gets and sets the property Keywords. One or more words or phrases that describe the HIT, separated by commas. These words are used in searches to find HITs.

Gets and sets the property Reward. The amount of money the Requester will pay a Worker for successfully completing the HIT.

Gets and sets the property HITTypeId. The ID of the newly registered HIT type.

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.

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.

Gets and sets the property AutoGrantedValue. The Qualification value to use for automatically granted Qualifications. This parameter is used only if the AutoGranted parameter is true.

Gets and sets the property Description. A long description for the Qualification type. On the Amazon Mechanical Turk website, the long description is displayed when a Worker examines a Qualification type.

Gets and sets the property Keywords. One or more words or phrases that describe the Qualification type, separated by commas. The keywords of a type make the type easier to find during a search.

Gets and sets the property Name. The name you give to the Qualification type. The type name is used to represent the Qualification to Workers, and to find the type using a Qualification type search. It must be unique across all of your Qualification types.

Gets and sets the property QualificationTypeStatus. The initial status of the Qualification type. Constraints: Valid values are: Active | Inactive

Gets and sets the property RetryDelayInSeconds. The number of seconds that a Worker must wait after requesting a Qualification of the Qualification type before the worker can retry the Qualification request. Constraints: None. If not specified, retries are disabled and Workers can request a Qualification of this type only once, even if the Worker has not been granted the Qualification. It is not possible to disable retries for a Qualification type after it has been created with retries enabled. If you want to disable retries, you must delete existing retry-enabled Qualification type and then create a new Qualification type with retries disabled.

Gets and sets the property Test. The questions for the Qualification test a Worker must answer correctly to obtain a Qualification of this type. If this parameter is specified, TestDurationInSeconds must also be specified. Constraints: Must not be longer than 65535 bytes. Must be a QuestionForm data structure. This parameter cannot be specified if AutoGranted is true. Constraints: None. If not specified, the Worker may request the Qualification without answering any questions.

Gets and sets the property Reason. A message explaining the reason for blocking the Worker. This parameter enables you to keep track of your Workers. The Worker does not see this message.

Gets and sets the property WorkerId. The ID of the Worker to block.

This is the response object from the CreateWorkerBlock operation.

Container for the parameters to the DeleteHIT operation. 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.
Disposing HITs can improve the performance of operations such as ListReviewableHITs and ListHITs.

Gets and sets the property HITId. The ID of the HIT to be deleted.

This is the response object from the DeleteHIT operation.

Container for the parameters to the DeleteQualificationType 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. DeleteQualificationType must wait for all the HITs that use the deleted Qualification type to be deleted before completing. It may take up to 48 hours before DeleteQualificationType completes and the unique name of the Qualification type is available for reuse with CreateQualificationType.

Gets and sets the property QualificationTypeId. The ID of the QualificationType to dispose.

This is the response object from the DeleteQualificationType operation.

Container for the parameters to the DeleteWorkerBlock operation. The DeleteWorkerBlock operation allows you to reinstate a blocked Worker to work on your HITs. This operation reverses the effects of the CreateWorkerBlock operation. You need the Worker ID to use this operation. If the Worker ID is missing or invalid, this operation fails and returns the message “WorkerId is invalid.” If the specified Worker is not blocked, this operation returns successfully.

Gets and sets the property Reason. A message that explains the reason for unblocking the Worker. The Worker does not see this message.

Gets and sets the property WorkerId. The ID of the Worker to unblock.

This is the response object from the DeleteWorkerBlock operation.

Container for the parameters to the GetFileUploadURL operation. The GetFileUploadURL operation generates and returns a temporary URL. You use the temporary URL to retrieve a file uploaded by a Worker as an answer to a FileUploadAnswer question for a HIT. The temporary URL is generated the instant the GetFileUploadURL operation is called, and is valid for 60 seconds. You can get a temporary file upload URL any time until the HIT is disposed. After the HIT is disposed, any uploaded files are deleted, and cannot be retrieved. Pending Deprecation on December 12, 2017. The Answer Specification structure will no longer support the FileUploadAnswer element to be used for the QuestionForm data structure. Instead, we recommend that Requesters who want to create HITs asking Workers to upload files to use Amazon S3.

The QualificationRequirement data structure describes a Qualification that a Worker must have before the Worker is allowed to accept a HIT. A requirement may optionally state that a Worker must have the Qualification in order to preview the HIT, or see the HIT in search results.

Gets and sets the property ActionsGuarded. Setting this attribute prevents Workers whose Qualifications do not meet this QualificationRequirement from taking the specified action. Valid arguments include "Accept" (Worker cannot accept the HIT, but can preview the HIT and see it in their search results), "PreviewAndAccept" (Worker cannot accept or preview the HIT, but can see the HIT in their search results), and "DiscoverPreviewAndAccept" (Worker cannot accept, preview, or see the HIT in their search results). It's possible for you to create a HIT with multiple QualificationRequirements (which can have different values for the ActionGuarded attribute). In this case, the Worker is only permitted to perform an action when they have met all QualificationRequirements guarding the action. The actions in the order of least restrictive to most restrictive are Discover, Preview and Accept. For example, if a Worker meets all QualificationRequirements that are set to DiscoverPreviewAndAccept, but do not meet all requirements that are set with PreviewAndAccept, then the Worker will be able to Discover, i.e. see the HIT in their search result, but will not be able to Preview or Accept the HIT. ActionsGuarded should not be used in combination with the RequiredToPreview field.

Gets and sets the property Comparator. The kind of comparison to make against a Qualification's value. You can compare a Qualification's value to an IntegerValue to see if it is LessThan, LessThanOrEqualTo, GreaterThan, GreaterThanOrEqualTo, EqualTo, or NotEqualTo the IntegerValue. You can compare it to a LocaleValue to see if it is EqualTo, or NotEqualTo the LocaleValue. You can check to see if the value is In or NotIn a set of IntegerValue or LocaleValue values. Lastly, a Qualification requirement can also test if a Qualification Exists or DoesNotExist in the user's profile, regardless of its value.

Gets and sets the property IntegerValues. The integer value to compare against the Qualification's value. IntegerValue must not be present if Comparator is Exists or DoesNotExist. IntegerValue can only be used if the Qualification type has an integer value; it cannot be used with the Worker_Locale QualificationType ID. When performing a set comparison by using the In or the NotIn comparator, you can use up to 15 IntegerValue elements in a QualificationRequirement data structure.

Gets and sets the property LocaleValues. The locale value to compare against the Qualification's value. The local value must be a valid ISO 3166 country code or supports ISO 3166-2 subdivisions. LocaleValue can only be used with a Worker_Locale QualificationType ID. LocaleValue can only be used with the EqualTo, NotEqualTo, In, and NotIn comparators. You must only use a single LocaleValue element when using the EqualTo or NotEqualTo comparators. When performing a set comparison by using the In or the NotIn comparator, you can use up to 30 LocaleValue elements in a QualificationRequirement data structure.

Gets and sets the property QualificationTypeId. The ID of the Qualification type for the requirement.

Gets and sets the property RequiredToPreview. DEPRECATED: Use the ActionsGuarded field instead. If RequiredToPreview is true, the question data for the HIT will not be shown when a Worker whose Qualifications do not meet this requirement tries to preview the HIT. That is, a Worker's Qualifications must meet all of the requirements for which RequiredToPreview is true in order to preview the HIT. If a Worker meets all of the requirements where RequiredToPreview is true (or if there are no such requirements), but does not meet all of the requirements for the HIT, the Worker will be allowed to preview the HIT's question data, but will not be allowed to accept and complete the HIT. The default is false. This should not be used in combination with the ActionsGuarded field.

The QualificationType data structure represents a Qualification type, a description of a property of a Worker that must match the requirements of a HIT for the Worker to be able to accept the HIT. The type also describes how a Worker can obtain a Qualification of that type, such as through a Qualification test.

Gets and sets the property AnswerKey. The answers to the Qualification test specified in the Test parameter.

Gets and sets the property AutoGranted. Specifies that requests for the Qualification type are granted immediately, without prompting the Worker with a Qualification test. Valid values are True | False.

Container for the parameters to the RejectAssignment operation. 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. Only the Requester who created the HIT can reject an assignment for the HIT.

Gets and sets the property AssignmentId. The ID of the assignment. The assignment must correspond to a HIT created by the Requester.

Gets and sets the property RequesterFeedback. A message for the Worker, which the Worker can see in the Status section of the web site.

Container for the parameters to the SendBonus operation. The SendBonus operation issues a payment of money from your account to a Worker. This payment happens separately from the reward you pay to the Worker when you approve the Worker's assignment. The SendBonus operation requires the Worker's ID and the assignment ID as parameters to initiate payment of the bonus. You must include a message that explains the reason for the bonus payment, as the Worker may not be expecting the payment.

If the bonus already exists in the system from a previous call using the same UniqueRequestToken, subsequent calls will return an error with a message containing the request ID.

Gets and sets the property WorkerId. The ID of the Worker being paid the bonus.

This is the response object from the SendBonus operation.

Container for the parameters to the SendTestEventNotification operation. The SendTestEventNotification operation causes Amazon Mechanical Turk to send a notification message as if a HIT event occurred, according to the provided notification specification. This allows you to test notifications without setting up notifications for a real HIT type and trying to trigger them using the website. When you call this operation, the service attempts to send the test notification immediately.

Gets and sets the property Notification. The notification specification to test. This value is identical to the value you would provide to the UpdateNotificationSettings operation when you establish the notification specification for a HIT type.

Gets and sets the property TestEventType. The event to simulate to test the notification specification. This event is included in the test message even if the notification specification does not include the event type. The notification specification does not filter out the test event.

This is the response object from the SendTestEventNotification operation.

MTurk exception

Constructs a new ServiceException with the specified error message.

Describes the error encountered.

Construct instance of ServiceException

Constructs a new instance of the ServiceException class with serialized data.

Container for the parameters to the UpdateExpirationForHIT operation. The UpdateExpirationForHIT operation allows you update the expiration time of a HIT. If you update it to a time in the past, the HIT will be immediately expired.

Gets and sets the property ExpireAt. The date and time at which you want the HIT to expire

Gets and sets the property HITId. The HIT to update.

This is the response object from the UpdateExpirationForHIT operation.

Container for the parameters to the UpdateHITReviewStatus operation. The UpdateHITReviewStatus operation updates the status of a HIT. If the status is Reviewable, this operation can update the status to Reviewing, or it can revert a Reviewing HIT back to the Reviewable status.

Gets and sets the property HITId. The ID of the HIT to update.

Gets and sets the property Revert. Specifies how to update the HIT status. Default is False.

Setting this to false will only transition a HIT from Reviewable to Reviewing
Setting this to true will only transition a HIT from Reviewing to Reviewable

This is the response object from the UpdateHITReviewStatus operation.

Container for the parameters to the UpdateHITTypeOfHIT operation. The UpdateHITTypeOfHIT operation allows you to change the HITType properties of a HIT. This operation disassociates the HIT from its old HITType properties and associates it with the new HITType properties. The HIT takes on the properties of the new HITType in place of the old ones.

Gets and sets the property HITId. The HIT to update.

Gets and sets the property HITTypeId. The ID of the new HIT type.

This is the response object from the UpdateHITTypeOfHIT operation.

Container for the parameters to the UpdateNotificationSettings operation. The UpdateNotificationSettings operation creates, updates, disables or re-enables notifications for a HIT type. If you call the UpdateNotificationSettings operation for a HIT type that already has a notification specification, the operation replaces the old specification with a new one. You can call the UpdateNotificationSettings operation to enable or disable notifications for the HIT type, without having to modify the notification specification itself by providing updates to the Active status without specifying a new notification specification. To change the Active status of a HIT type's notifications, the HIT type must already have a notification specification, or one must be provided in the same call to UpdateNotificationSettings.

Gets and sets the property Active. Specifies whether notifications are sent for HITs of this HIT type, according to the notification specification. You must specify either the Notification parameter or the Active parameter for the call to UpdateNotificationSettings to succeed.

Gets and sets the property HITTypeId. The ID of the HIT type whose notification specification is being updated.

Gets and sets the property Notification. The notification specification for the HIT type.

This is the response object from the UpdateNotificationSettings operation.

Container for the parameters to the UpdateQualificationType operation. 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. You can also update the AutoGranted and AutoGrantedValue attributes of the Qualification type.

Gets and sets the property AnswerKey. The answers to the Qualification test specified in the Test parameter, in the form of an AnswerKey data structure.

Gets and sets the property AutoGrantedValue. The Qualification value to use for automatically granted Qualifications. This parameter is used only if the AutoGranted parameter is true.

Gets and sets the property Description. The new description of the Qualification type.

Gets and sets the property QualificationTypeId. The ID of the Qualification type to update.

Gets and sets the property QualificationTypeStatus. The new status of the Qualification type - Active | Inactive

Gets and sets the property RetryDelayInSeconds. The amount of time, in seconds, that Workers must wait after requesting a Qualification of the specified Qualification type before they can retry the Qualification request. It is not possible to disable retries for a Qualification type after it has been created with retries enabled. If you want to disable retries, you must dispose of the existing retry-enabled Qualification type using DisposeQualificationType and then create a new Qualification type with retries disabled using CreateQualificationType.

Gets and sets the property TestDurationInSeconds. The number of seconds the Worker has to complete the Qualification test, starting from the time the Worker requests the Qualification.

This is the response object from the UpdateQualificationType operation.

Gets and sets the property QualificationType. Contains a QualificationType data structure.

The WorkerBlock data structure represents a Worker who has been blocked. It has two elements: the WorkerId and the Reason for the block.

Gets and sets the property Reason. A message explaining the reason the Worker was blocked.

Gets and sets the property WorkerId. The ID of the Worker who accepted the HIT.

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). Note: AssociateQualificationWithWorker does not affect any pending Qualification requests for the Qualification by the Worker. If you assign a Qualification to a Worker, then later grant a Qualification request made by the Worker, the granting of the request may modify the Qualification score. To resolve a pending Qualification request without affecting the Qualification the Worker already has, reject the request with the RejectQualificationRequest operation.

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.

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.
Disposing HITs can improve the performance of operations such as ListReviewableHITs and ListHITs.

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. DeleteQualificationType must wait for all the HITs that use the deleted Qualification type to be deleted before completing. It may take up to 48 hours before DeleteQualificationType completes and the unique name of the Qualification type is available for reuse with CreateQualificationType.

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. You can also update the AutoGranted and AutoGrantedValue attributes of the Qualification type.
