/AWS1/CL_SWF=>RESPONDACTIVITYTASKCOMPLETED()
¶
About RespondActivityTaskCompleted¶
Used by workers to tell the service that the ActivityTask identified
by the taskToken
completed successfully with a result
(if provided).
The result
appears in the ActivityTaskCompleted
event in the
workflow history.
If the requested task doesn't complete successfully, use RespondActivityTaskFailed instead. If the worker finds that the task is
canceled through the canceled
flag returned by RecordActivityTaskHeartbeat, it should cancel the task, clean up and then call
RespondActivityTaskCanceled.
A task is considered open from the time that it is scheduled until it is closed. Therefore a task is reported as open while a worker is processing it. A task is closed after it has been specified in a call to RespondActivityTaskCompleted, RespondActivityTaskCanceled, RespondActivityTaskFailed, or the task has timed out.
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. -
You cannot use an IAM policy to constrain this action's parameters.
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.
