How does orchestration using Composite APIs function?

Orchestration using Composite APIs functions by utilizing outputs from one API call as inputs for another. This approach allows for a more efficient and streamlined data flow between various services or components. In this context, composite APIs enable a single request to encompass multiple operations across different services, ensuring that the result of one operation can be immediately leveraged in subsequent operations. This chaining of API calls is essential for complex business processes where the output of one step must dictate the behavior or data of the next step.

For example, when integrating systems, if an API retrieves customer data, that data can then be directly passed to another API for processing or updating records without requiring the integration to handle the intermediate steps manually. This enhances performance and simplifies integration logic, promoting better system interconnectivity and reducing latency.

The other options describe different approaches to API calls. Processing all requests in parallel suggests simultaneous execution without dependency, while making calls independent of each other implies a lack of connection between API functionalities. Finally, requiring manual input at each stage indicates an interactive process rather than the automated nature of orchestration through Composite APIs. These options do not capture the inherent efficiency and dependency management that orchestration through composite calls provides.
