The Designer comes with many adapters (see Adapters) that allow you to access a variety of backends via their REST interface. Request to REST services, and via the REST adapter use the HTTP protocol.
With this protocol, the xUML Runtime serves a set of standard headers (via libcurl) as described below (Standard HTTP Headers with xUML Service Adapters). You can use these headers to trace requests through multiple systems. Also, you can overwrite these standard headers using the concept of HTTP header roles.
