What is API Orchestration API orchestration refers to the process of integrating and managing multiple APIs to perform a unified task and create a seamless user experience. API orchestration can involve splitting, merging, or routing data to different APIs, depending on the desired outcome.

Data Transformation Not every request for data is delivered or received using a common format. Both the client and the server could need the data answers to be transmitted in a certain format, requiring data transformation to enable communication in a standard call format. Using its transformation capabilities, the orchestration layer can intervene to guarantee that payloads are prepared appropriately. 

Runtime management The orchestration layer can intervene before requests reach your API backend by treating each component of your application as a collection of microservices. Regarding security, this has a lot of benefits (runtime policies checking for malicious code threats). As a result, protocols, data validation, and error handling/logging are standardised. 

Integrating legacy system Language agnostic Orchestration platforms like Conductor can help you connect with your legacy systems. Mixing of API types, such as REST and SOAP, can lead to major headaches when trying to use multiple APIs together. In steps, the orchestration layer normalises the data structures. This manages the flow of data and lets you communicate with the most neglected APIs and microservices. 

Role-based permissions systems can be deployed since the orchestration layer can handle the authentication flow between microservices. This enables you to grant chosen people that fit a particular role access to only specific data. Authentication and Role Based Access Control
