Representational State Transfer Protocol (REST) applications use HTTP instead of the more complex SOAP protocol to make calls between machines. The REST integration interface in the Pega Platform supports interactions with external systems through Web services.
Use the Application Explorer to see Service REST rules in your application. Use the Records Explorer to list all Service REST rules that are available to you.
Service REST rules belong to the Integration-Services category. A Service REST rule is an instance of the Rule-Service-REST class.
You can collect performance statistics about the resources used by a service in a Comma-Separated-Values (CSV) file, accessed from the Log menu. See Performance tool — Statistics for services in the SERVICES-PAL log.
You can trace the operation of a Service REST rule and the service activity it calls. See Tracing services.
