Why is it important for Process APIs to be independent of source systems?

The importance of Process APIs being independent of source systems primarily lies in their ability to facilitate easier data manipulation and logic implementation. When Process APIs do not rely on specific source systems, they can serve as an abstraction layer that provides a uniform interface for accessing and processing data from various back-end services and databases.

This independence allows developers to design and implement data processing logic without being constrained by the details of any one system's structure or data format. As a result, this flexibility enables teams to make changes to business logic, integrate new data sources, or adapt to changes in backend systems without needing to overhaul the entire architecture. The ability to manipulate data more easily also fosters better reuse and scalability of APIs across different projects and applications, ultimately leading to a more agile development process.

While other options may touch upon relevant points within the broader context of API design and system integration, none encapsulate the essence of the independence of Process APIs as effectively as the capacity for easier data manipulation and logic implementation.
