API orchestration is the process of integrating applications into a single offering. API orchestration typically requires creating a single API that offers valuable functions to its consumers, often by making multiple calls to multiple different services to respond to a single API request
An orchestration layer steps in when multiple API services need to be coordinated. It adds the ability to manage data formatting between separate services, where requests and responses need to be split, merged or routed. By adding this abstraction layer you provide your API with a level of intelligence for communication between services, while handling vital authentication tasks. Adding an orchestration layer to your API gives you many benefits like
