In a Pega application, what best practice should be followed for handling exceptions in integrations?

Using a centralized error handling strategy for all integrations is a best practice because it ensures consistency and maintainability in how exceptions are managed throughout the application. By having a unified approach, developers can easily track, log, and respond to errors that may arise across various integrations, rather than dealing with disparate handling methods scattered throughout the codebase.

Centralized error handling allows for better monitoring, reduces the risk of overlooking issues that could lead to system failures, and enhances the ability to implement comprehensive logging and notification procedures. This approach also simplifies troubleshooting because errors can be diagnosed from a single point, rather than having to sift through multiple integration endpoints to discover how each one handles exceptions.

In contrast, approaches that involve ignoring exceptions, allowing each integration to manage its own exceptions independently, or only documenting exceptions without taking action would lead to inconsistent handling of issues, increased difficulty in identifying the sources of problems, and poor user experience if integrations fail without appropriate responses.
