Hi,

Please enable debug mode for below class to log the request and response xml for rest connector.

com.pega.pegarules.integration.engine.internal.connect.rest.RESTConnector

Thank You,

The above debugger is for outgoing Connect REST requests.

I don't think there is a class for logging the entire incoming XML for Service REST.  There are other classes ServiceAPI and Utils classes which help to confirm if incoming the request is received by Pega, otherwise, I would generally use Service Trace Watch from corresponding Service REST rule.
