C# REST PayPal API - How to pass the custom variable?

Question

I've read about the the ability to pass a custom variable to along with my paypal payment in order to identify later on. Is it possible only through a client side request (paypal button + HTML form) or can I also achieve this ability using the server side REST Api (NOT the adaptive payments Api) for C#. I searched a lot and will appreciate any help on this one.

Thnaks, Ohad.

REST API没有提供通过自定义值发送传递的方法。
