Get a List of RAPID Routines via WebServices

Hello, I am trying to figure out the best way to retrieve a list of all the routines which exist in a RAPID module. In the PC SDK There was a Module class which had a GetRoutines() method which returned an array of Routine. I was hoping to find something similar in the Web API.

I was looking at using GET /rw​/rapid​/tasks​/{task}​/modules​/{module}​/routine but this requires row and column parameters which I am unable to supply as my front end application does not necessarily know about the existence of a routine prior to fetching them from RAPID.

Thanks in advance,
