The route is the offset from the application base URL. The route can contain parameter which are translated by the binder, to your method parameters.

So the first route, customers/{customerId}/orders would be called as https://someserver/customers/123/orders (route = customers/123/orders), which will result in a call similar to GetOrdersByCustomer(123).

The second route, customers/{customerId}/orders/{orderId} would be called as https://someserver/customers/123/orders/456 (route = customers/123/orders/456), which will result in a call similar to GetOrderByCustomer(123, 456).
