Service REST rules

Version:

Only available versions of this content are shown in the dropdown

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.

Access

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.

Category

Service REST rules belong to the Integration-Services category. A Service REST rule is an instance of the Rule-Service-REST class.

Performance logging

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.

  • Creating a Service REST rule

    You can create Service REST rules to expose the REST APIs that can be called by another application to invoke an action or to retrieve data from Pega Platform. You need a service package and a Service REST rule to create and expose a Service REST from your application.

  • Defining resource and processing details for a Service REST rule

    Use the Service tab of the Service REST rule to configure the mapping of the URL path parameters, data transforms, and other configuration options for your service.

  • Service REST methods

    You can use the following methods when you configure Service REST rules.

  • Endpoint configuration upgrade

    Take advantage of all available configuration options for a URL by upgrading a REST connector to the new endpoint configuration. Use the Upgrade to new endpoint configuration button to upgrade a REST connector that was made before Pega Platform 8.3.

  • Distinct URI specification for service REST rules

    Different service REST rules are specified for different resource URIs. This functionality provides different processing options, request handling, and response handling for each distinct resource URI. Additionally, it eliminates the need to maintain complex logic used to handle all possible resource URI paths.

  • Service REST monitoring

    You can monitor Service REST request and response data and view the results of rule invocation by using a combination of dynamic system settings and options on the Service Package and Service REST rule forms. Monitoring is useful for debugging your application during development, for example, if a request is failing.
