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 handle the unavailability of a system of record when using a SOAP connector, the most effective approach is to implement the retry logic in the connector's error handler flow. This flow can be configured to wait for a specified duration (in this case, an hour) before retrying the connection. If the system remains unavailable after the retry, the flow can then proceed to send a notification to the system administrator. This approach encapsulates the error handling logic within the connector's flow, making it reusable and maintainable.References: Pega Community documentation on connector error handling and SOAP connectors.

Pega Web Mashup is ideal for scenarios where minimal resources are available for updating the Pega Platform with each new release, as it allows external applications to embed Pega UI elements with minimal maintenance. Additionally, it's useful when users are expected to create cases, open assignments, and manage data privacy within an embedded Pega frame in an external web page.
