How do you specify a Notification Writer when publishing an FME workspace via the FME REST API?

My workspace is run as a result of a directory watcher publication event. The event helpfully passes the JSON message about the location of the new file. I have the DirectoryWatcher reader in my workspace to read the JSON message.

 

 

When I publish to our FME Server 2014 using the wizard, I am able to specify which reader should be used to read in the notification event: this is on the Register Services screen, on the Notification Service line, clicking Edit..., there I can specify the Notification Reader. Similarly, I can specify the writer that will be used for the publish event (i.e. the Notification Writer).

 

 

In order to do automated deployment, I am using the FME Server REST API (v2). I am able to publish a workspace sucessfully using the API, as well as create topics and manage subscriptions. However, I cannot find a way of specifying which reader/writer should be used for receiving/sending the notification event message.

 

 

Is it possible to specify the Notification Reader or Notification Writer using the FME REST API?
