SDK for PHP 3.x

Client: Aws\MTurk\MTurkClient
Service ID: mturk-requester
Version: 2017-01-17

This page describes the parameters and results for the operations of the Amazon Mechanical Turk (2017-01-17), and shows how to use the Aws\MTurk\MTurkClient object to call the described operations. This documentation is specific to the 2017-01-17 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

ListAssignmentsForHIT
ListBonusPayments
ListHITs
ListHITsForQualificationType
ListQualificationRequests
ListQualificationTypes
ListReviewPolicyResultsForHIT
ListReviewableHITs
ListWorkerBlocks
ListWorkersWithQualificationType

Operations

AcceptQualificationRequest

$result = $client->acceptQualificationRequest([/* ... */]);
$promise = $client->acceptQualificationRequestAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->acceptQualificationRequest([
    'IntegerValue' => <integer>,
    'QualificationRequestId' => '<string>', // REQUIRED
]);

Parameter Details

Members
IntegerValue
Type: int

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.

QualificationRequestId
Required: Yes
Type: string

The ID of the Qualification request, as returned by the GetQualificationRequests operation.

Result Syntax

[]

Result Details

The results for this operation are always empty.

Errors

ServiceFault:

Amazon Mechanical Turk is temporarily unable to process your request. Try your call again.

RequestError:

Your request is invalid.

ApproveAssignment

$result = $client->approveAssignment([/* ... */]);
$promise = $client->approveAssignmentAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->approveAssignment([
    'AssignmentId' => '<string>', // REQUIRED
    'OverrideRejection' => true || false,
    'RequesterFeedback' => '<string>',
]);

Parameter Details

Members
AssignmentId
Required: Yes
Type: string

The ID of the assignment. The assignment must correspond to a HIT created by the Requester.

OverrideRejection
Type: boolean

A flag indicating that an assignment should be approved even if it was previously rejected. Defaults to False.

RequesterFeedback
Type: string

A message for the Worker, which the Worker can see in the Status section of the web site.

Result Syntax

[]

Result Details

The results for this operation are always empty.

Errors

ServiceFault:

Amazon Mechanical Turk is temporarily unable to process your request. Try your call again.

RequestError:

Your request is invalid.

AssociateQualificationWithWorker

$result = $client->associateQualificationWithWorker([/* ... */]);
$promise = $client->associateQualificationWithWorkerAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->associateQualificationWithWorker([
    'IntegerValue' => <integer>,
    'QualificationTypeId' => '<string>', // REQUIRED
    'SendNotification' => true || false,
    'WorkerId' => '<string>', // REQUIRED
]);

Parameter Details

Members
IntegerValue
Type: int

The value of the Qualification to assign.

QualificationTypeId
Required: Yes
Type: string

The ID of the Qualification type to use for the assigned Qualification.

SendNotification
Type: boolean

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.

WorkerId
Required: Yes
Type: string

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

Result Syntax

[]

Result Details

The results for this operation are always empty.

Errors

ServiceFault:

Amazon Mechanical Turk is temporarily unable to process your request. Try your call again.

RequestError:

Your request is invalid.

CreateAdditionalAssignmentsForHIT

$result = $client->createAdditionalAssignmentsForHIT([/* ... */]);
$promise = $client->createAdditionalAssignmentsForHITAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->createAdditionalAssignmentsForHIT([
    'HITId' => '<string>', // REQUIRED
    'NumberOfAdditionalAssignments' => <integer>, // REQUIRED
    'UniqueRequestToken' => '<string>',
]);

Parameter Details

Members
HITId
Required: Yes
Type: string

The ID of the HIT to extend.

NumberOfAdditionalAssignments
Required: Yes
Type: int

The number of additional assignments to request for this HIT.

UniqueRequestToken
Type: string

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.

Result Syntax

[]

Result Details

The results for this operation are always empty.

Errors

ServiceFault:

Amazon Mechanical Turk is temporarily unable to process your request. Try your call again.

RequestError:

Your request is invalid.

CreateHIT

$result = $client->createHIT([/* ... */]);
$promise = $client->createHITAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->createHIT([
    'AssignmentDurationInSeconds' => <integer>, // REQUIRED

Parameter Details

Members
AssignmentDurationInSeconds
Required: Yes
Type: long (int|float)

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.

AssignmentReviewPolicy
Type: ReviewPolicy structure

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.

AutoApprovalDelayInSeconds
Type: long (int|float)

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.

Description
Required: Yes
Type: string

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.

HITLayoutId
Type: string

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.

HITLayoutParameters
Type: Array of HITLayoutParameter structures

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

HITReviewPolicy
Type: ReviewPolicy structure

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

Keywords
Type: string

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

LifetimeInSeconds
Required: Yes
Type: long (int|float)

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.

MaxAssignments
Type: int

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

QualificationRequirements
Type: Array of QualificationRequirement structures

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.

Question
Type: string

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.

RequesterAnnotation
Type: 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.

Reward
Required: Yes
Type: string

The amount of money the Requester will pay a Worker for successfully completing the HIT.

Title
Required: Yes
Type: string

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.

UniqueRequestToken
Type: 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.

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.

CreateHITWithHITType

$result = $client->createHITWithHITType([/* ... */]);
$promise = $client->createHITWithHITTypeAsync([/* ... */]);

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.

Parameter Details

Members
AssignmentReviewPolicy
Type: ReviewPolicy structure

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.

HITLayoutId
Type: string

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.

HITLayoutParameters
Type: Array of HITLayoutParameter structures

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

HITReviewPolicy
Type: ReviewPolicy structure

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

HITTypeId
Required: Yes
Type: string

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

LifetimeInSeconds
Required: Yes
Type: long (int|float)

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.

MaxAssignments
Type: int

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

Question
Type: string

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.

RequesterAnnotation
Type: 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.

UniqueRequestToken
Type: 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.

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.

DeleteHIT

$result = $client->deleteHIT([/* ... */]);
$promise = $client->deleteHITAsync([/* ... */]);

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.

DeleteQualificationType

$result = $client->deleteQualificationType([/* ... */]);
$promise = $client->deleteQualificationTypeAsync([/* ... */]);

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.

$promise = $client->deleteWorkerBlockAsync([/* ... */]);

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.

ListAssignmentsForHIT

$result = $client->listAssignmentsForHIT([/* ... */]);
$promise = $client->listAssignmentsForHITAsync([/* ... */]);

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.

Results are sorted and divided into numbered pages and the operation returns a single page of results. You can use the parameters of the operation to control sorting and pagination.

Parameter Syntax

$result = $client->listAssignmentsForHIT([
    'AssignmentStatuses' => ['<string>', ...],

$promise = $client->sendBonusAsync([/* ... */]);

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. Amazon Mechanical Turk collects a fee for bonus payments, similar to the HIT listing fee. This operation fails if your account does not have enough funds to pay for both the bonus and the fees.

UpdateNotificationSettings

$result = $client->updateNotificationSettings([/* ... */]);
$promise = $client->updateNotificationSettingsAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->updateNotificationSettings([
    'Active' => true || false,
    'HITTypeId' => '<string>', // REQUIRED
    'Notification' => [
        'Destination' => '<string>', // REQUIRED

UpdateQualificationType

$result = $client->updateQualificationType([/* ... */]);
$promise = $client->updateQualificationTypeAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->updateQualificationType([
    'AnswerKey' => '<string>',
    'AutoGranted' => true || false,
    'AutoGrantedValue' => <integer>,
    'Description' => '<string>',
    'QualificationTypeId' => '<string>', // REQUIRED

Type: long (int|float)

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.

Test
Type: string

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.

TestDurationInSeconds
Type: long (int|float)

QualificationRequirement

Description

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.

Members
ActionsGuarded
Type: string

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.

Comparator
Required: Yes
Type: string

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.

IntegerValues
Type: Array of ints

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.

LocaleValues
Type: Array of Locale structures

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.

QualificationTypeId
Required: Yes
Type: string

The ID of the Qualification type for the requirement.

RequiredToPreview
Type: boolean

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.
