How do I pass a dynamic parameter as a part of the URL of a REST service while using WSO2 ESB Proxy Service?

I am trying to simply host a REST service as a proxy service in WSO2 ESB. I am using Custom Proxy to do this. When I run the created proxy, I am not able to pass parameters to the proxy service at run time. How do I do this?

My REST service will be hit on a URL of format:http://ip:host/requestMapping/{name}

The parameter 'name' has to be passed from the UI through the ESB to the service through a proxy service hosted on the ESB. Can you help me with the steps to follow to make this work?

I tried using this page: http://wso2.com/library/articles/2013/12/restful-integration-with-wso2-esb/

But that is for creating APIs which I have been successfully in creating. But I am unable to do this using Proxy services.

Basically in my program, when the user interacts with the UI, he enters a name as input. This name has to be passed to the proxy service hosted in the ESB which should forward this as a path variable to my REST service.

Right now, my service body is:

<inSequence>
  <send>
   <endpoint>
   <http method="POST" uri-template="http://ip:port/resourceMapping/{uri.var.name}"></http>

    </endpoint>
   </send>
</inSequence>
<outSequence>
  <send></send>
</outSequence>

When I run this, instead of sending the name as entered by the user, it sends "uri.var.name" to the REST service. On the other hand, if I define a property tag and define a value for it and then do this, the REST service gets the value of the property that I have set. But I need this value to be sent dynamically by the user so I can't define property and value inside.

Please help me.

I think, the best approach is to use API in this case because the request to the ESB is REST and endpoint also accepting REST. This is the best practice.
