API Reference (API Version 2012-01-25)

RegisterActivityType

Registers a new activity type along with its configuration settings in the specified domain.

Important

A TypeAlreadyExists fault is returned if the type already exists in the domain. You cannot change any configuration settings of the type after its registration, and it must be registered as a new version.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

  • Use a Resource element with the domain name to limit the action to only specified domains.

  • Use an Action element to allow or deny permission to call this action.

  • Constrain the following parameters by using a Condition element with the appropriate keys.

    • defaultTaskList.name: String constraint. The key is swf:defaultTaskList.name.

    • name: String constraint. The key is swf:name.

    • version: String constraint. The key is swf:version.

If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter is set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

Request Syntax

{ "defaultTaskHeartbeatTimeout": "string", "defaultTaskList": { "name": "string" }, "defaultTaskPriority": "string", "defaultTaskScheduleToCloseTimeout": "string", "defaultTaskScheduleToStartTimeout": "string", "defaultTaskStartToCloseTimeout": "string", "description": "string", "domain": "string", "name": "string", "version": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

defaultTaskHeartbeatTimeout

If set, specifies the default maximum time before which a worker processing a task of this type must report progress by calling RecordActivityTaskHeartbeat. If the timeout is exceeded, the activity task is automatically timed out. This default can be overridden when scheduling an activity task using the ScheduleActivityTask Decision. If the activity worker subsequently attempts to record a heartbeat or returns a result, the activity worker receives an UnknownResource fault. In this case, Amazon SWF no longer considers the activity task to be valid; the activity worker should clean up the activity task.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

Type: String

Length Constraints: Maximum length of 8.

Required: No

defaultTaskList

If set, specifies the default task list to use for scheduling tasks of this activity type. This default task list is used if a task list isn't provided when a task is scheduled through the ScheduleActivityTask Decision.

Type: TaskList object

Required: No

defaultTaskPriority

The default task priority to assign to the activity type. If not assigned, then 0 is used. Valid values are integers that range from Java's Integer.MIN_VALUE (-2147483648) to Integer.MAX_VALUE (2147483647). Higher numbers indicate higher priority.

For more information about setting task priority, see Setting Task Priority in the in the Amazon SWF Developer Guide..

Type: String

Required: No

defaultTaskScheduleToCloseTimeout

If set, specifies the default maximum duration for a task of this activity type. This default can be overridden when scheduling an activity task using the ScheduleActivityTask Decision.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

Type: String

Length Constraints: Maximum length of 8.

Required: No

defaultTaskScheduleToStartTimeout

If set, specifies the default maximum duration that a task of this activity type can wait before being assigned to a worker. This default can be overridden when scheduling an activity task using the ScheduleActivityTask Decision.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

Type: String

Length Constraints: Maximum length of 8.

Required: No

defaultTaskStartToCloseTimeout

If set, specifies the default maximum duration that a worker can take to process tasks of this activity type. This default can be overridden when scheduling an activity task using the ScheduleActivityTask Decision.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

Type: String

Length Constraints: Maximum length of 8.

Required: No

description

A textual description of the activity type.

Type: String

Length Constraints: Maximum length of 1024.

Required: No

domain

The name of the domain in which this activity is to be registered.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: Yes

name

The name of the activity type within the domain.

The specified string must not start or end with whitespace. It must not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f-\u009f). Also, it must not contain the literal string arn.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: Yes

version

The version of the activity type.

Note

The activity type consists of the name and version, the combination of which must be unique within the domain.

The specified string must not start or end with whitespace. It must not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f-\u009f). Also, it must not contain the literal string arn.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: Yes

Response Elements

If the action is successful, the service sends back an HTTP 200 response with an empty HTTP body.

Errors

For information about the errors that are common to all actions, see Common Errors.

LimitExceededFault

Returned by any operation if a system imposed limitation has been reached. To address this fault you should either clean up unused resources or increase the limit by contacting AWS.

HTTP Status Code: 400

OperationNotPermittedFault

Returned when the caller doesn't have sufficient permissions to invoke the action.

HTTP Status Code: 400

TypeAlreadyExistsFault

Returned if the type already exists in the specified domain. You get this fault even if the existing type is in deprecated status. You can specify another version if the intent is to create a new distinct version of the type.

HTTP Status Code: 400

UnknownResourceFault

Returned when the named resource cannot be found with in the scope of this operation (region or domain). This could happen if the named resource was never created or is no longer available for this operation.

HTTP Status Code: 400
