SWF / Client / respond_activity_task_completed
Used by workers to tell the service that the ActivityTask identified by the
taskTokencompleted successfully with a
result(if provided). The
resultappears in the
ActivityTaskCompletedevent 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
canceledflag 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.
You can use IAM policies to control this action’s access to Amazon SWF resources as follows:
Resourceelement with the domain name to limit the action to only specified domains.
Actionelement 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
causeparameter 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.

response = client.respond_activity_task_completed( taskToken='string', result='string' )
taskToken (string) –
taskTokenof the ActivityTask.
taskTokenis generated by the service and should be treated as an opaque value. If the task is passed to another process, its
taskTokenmust also be passed. This enables it to provide its progress and respond with results.
result (string) – The result of the activity task. It is a free form string that is implementation specific.
