Zoho CRM APi v2 not triggering workflows

Zoho CRM APi v2 not triggering workflows

I have noticed that the new implementation is not triggering workflows as the v1 API was.

I am using the PHP SDK and the code:
$trigger=array("workflow","approval","blueprint");
$responseIns = $record->create($trigger)
but, while the record is created, the workflow does not run.
Having looked at the forums it appears a few people had similar problems, but I'm not sure what the resolution was.
