// RespondActivityTaskCompletedRequest returns a request value for making API operation for
// Amazon Simple Workflow Service.
//
// 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 (https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dg-basic.html#swf-dev-timeout-types).
//
// 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 (https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html)
// in the Amazon SWF Developer Guide.
