Which API builds on the System API by combining data with business logic?

The Process API is designed to build upon the System API by integrating data with business logic. In the API-led connectivity approach that MuleSoft promotes, System APIs are responsible for exposing and managing the underlying data sources, such as databases or third-party services. However, these APIs usually focus solely on data retrieval and do not incorporate any business rules or workflows.

The Process API serves as an intermediary layer that takes the data provided by System APIs and enriches it with additional business logic. This means it can perform operations like data transformation, aggregation, and orchestration of multiple System APIs to produce a more tailored data response that aligns with business requirements. By utilizing Process APIs, organizations can create more sophisticated applications that leverage the foundational data while incorporating the necessary business rules and processes, making them more efficient and aligned with business goals.

In contrast, other types of APIs like Experience APIs are typically focused on exposing data to specific user interfaces or external applications, while Management APIs deal with the administration and monitoring of APIs. Therefore, the Process API's unique role in combining data with business logic makes it the correct choice in this context.
