Is creating a POST REST Service like "https://tibco.service/sendtoqueue/queue?queuename" Using post data possible with TIBCO?

I would like to specify application/x-www-form-urlencoded which should allow the consumer to pass just about anything as data.  In this case I am looking to pass a variety of different XMLs (migrating a legacy application which eventually will be converted to JSONs but for now we would just like to pass the existing XMLs).  Any examples would be appreciated.  BusinessWorks Version 5.13 with REST/JSON version
