RespondActivityTaskCanceled Method (respondActivityTaskCanceledRequest)
AmazonAmazon.SimpleWorkflowAmazonSimpleWorkflowRespondActivityTaskCanceled(RespondActivityTaskCanceledRequest) Did this page help you?   Yes   No    Tell us about it...

Used by workers to tell the service that the ActivityTask identified by the taskToken was successfully canceled. Additional details can be optionally provided using the details argument.

These details (if provided) appear in the ActivityTaskCanceled event added to the workflow history.

IMPORTANT: Only use this operation if the canceled flag of a RecordActivityTaskHeartbeat request returns true and if the activity can be safely undone or abandoned.

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.
