The two most common ways to expose your application to an external system are to leverage the Pega API (B) and to create a web service with the Service wizard (D). The Pega API provides a set of out-of-the-box RESTful endpoints for performing operations within the Pega Platform. The Service wizard simplifies the creation of SOAP or REST services, enabling external systems to interact with Pega applications.References: Pega Community documentation on Pega API and Service wizard.

To report potholes through a mobile application using the Pega API, the POST/cases method would be used to submit the report case, and the GET/casetypes method would be used to access the related case type to ensure the correct case type is used for the report. References: Pega Platform API Guide.

A Declare OnChange rule is appropriate in a scenario where an immediate automatic response is required to a property change. For instance, when a manager approves a case (D), the case is routed back to the appropriate case worker. The OnChange rule can detect the approval and automatically perform the routing.
