After a basic lookup on the APIs exposed ,looks like currently there is no webhook which are executed when my order gets filled.Rather I am required to poll orders and check if they are executed(correct me if I am wrong). Polling from client side has its disadvantages.
This is almost ready. We have a "Postback" API that'll send you an HTTP post signal with some payload when an order's state changes (completed, cancelled, rejected). I'll make an announcement soon.
