API orchestration

API orchestration is the centralized control layer that sequences, transforms, and coordinates multiple API calls into a single, coherent workflow.

This technology acts as your digital conductor, consolidating a complex, multi-step business process—like a full e-commerce checkout or a user registration—into one front-end call. The orchestration layer manages the entire flow: it sequences calls, applies conditional logic, transforms data (e.g., JSON to XML) between services, and enforces robust error handling across disparate systems (Source 1.2, 1.4, 1.8). This approach shifts complexity from the client application to the backend, enabling cleaner microservices architecture and improving client-side performance. Dedicated platforms like Kong, n8n, or Orkes (built on Netflix Conductor) are often used to implement these high-efficiency, multi-step workflows (Source 1.1).
