Using embedded parameters in REST Outbound WS endpoint

We have an external REST API where the endpoint is using embedded parameters.

I have tried to search for some examples, but so far no luck.

The endpoint looks like this: https://hostname/path/{parameter}/path/{parameter}

The proxy BS does not contain any IO, only the method with parameters.

If we simulate and add the parameters as a propertyset, the call to the external service is just an empty DELETE operation.

Anyone ever had this type of outbound calls before from Siebel ?
