Testing WCF API with path parameters in Postman

Question

I am creating an API with WCF (C #) and testing it with Postman. It seems that I'm having problems using the "Params" section in Postman, since it will convert any key value pairs that I entered into Parallel Params.

My contract defines a UriTemplate so ...

    [OperationContract]
    [WebGet(UriTemplate = "/GetClientDataFromAlias/Alias/{alias}", 
                RequestFormat = WebMessageFormat.Json,
                ResponseFormat = WebMessageFormat.Json)]
    GetClientDataFromAliasResponse GetClientDataFromAlias(string alias);

However, when I run the request through Postman, the URL is converted to the following ...

http://troikawcf.localhost/ClientWCFService.svc/GetClientDataFromAlias?Alias=myalias

What I would like to translate is the following: comply with my contract

http://troikawcf.localhost/ClientWCFService.svc/GetClientDataFromAlias/Alias/myalias

Am I missing a setting in Postman to set all parameters in Path format? Or do I need to change my contract to use Query String Parameters?

For more information, see the screenshot below ...

Many thanks
