OSB and REST

Question

Hi everyone,
I have the requirement of develop a proxy service that consumes a RESTful service of another system called "Provider", the integration is like this, its very simple.
CLIENT >>>> OSB >>>> PROVIDER
   soap     --      soap      --   http
the problem i have is i dont know how to call a RESTful service via POST method , i have seen various examples but they only specifies to consume the REST service via GET method and not another method, to be more specific, i dont know how to do the mapping of the xml request to a REST service request in the case of a POST method, because the REST service can not receive a xml, which of the variables (indbound, outbound, body) of the proxy service i do the mapping of the xml input for pass the values to a RESTful SERVICE. ???
I will pass what i have...
this xml for example
<OrderNotificaction>
      <OrderNumber>12345</OrderNumber>
      <OrderStatus>20</OrderStatus>
</OrderNotification>
for OrderStatus > 20 = shipped
for OrderStatus > 10 = handling
and the REST service is consumed in this url, with this structure
http://host/api/orders/number/status
the mapping will result in some like this, if im not mistaken
http://host/api/orders/12345/shipped
i have to pass the values to the url with a routing options action to concat the parameters? or i can put the values of the xml in a variable of the proxy service for POST method? or both?
or a REST service can receive a xml request?
thanks in advanced

Try this:
1. Create a business service to call the Provider service.
2. In the Proxy route node, add a route action to invoke the above business service.
3. In the Route action add routing options and set URL to a new value, you can write XQUery expression to create the endpoint as required (in your case http://host/api/orders/12345/shipped )
