Using Mail Transport Rules and the Exchange AWS API

Question

I am looking to programmatically Enable and Disable hub transport rules from VS.NET and was hoping these functions would be available via the REST API. However, I can't find any references, which indicates that perhaps they don't exist. 
The rules I want to access can be used from PowerShell "Enable-TransportRule" and "Disable-TransportRule" and I can use them fine from Powershell.
So, my first question is, are these rules available from the Exchange EWS API? They need to be triggered when users perform certain events within the application.
If not, I am guessing I will be able to automate these cmdlets into a C# application or ASP.NET/C# application. Is this a correct assumption?
Thanks.
Jonathan.

No you can't set Transport rules from EWS, EWS is a mailbox access API and setting Transport Rule would be considered an Administrative Task so you need to use and Admin API which for Exchange is still the Exchange Management Shell. You can automate
the EMS cmdlet with Managed code (eg you could front end them with your own rest service) using Remote Powershell the best place to start would be
