In which order are the API Client, API Implementation, and API Interface components called in...

Correction Note:The provided PDF Answer Key listsBas the answer. However, based on standard MuleSoft and REST architecture principles,Ais the correct logical flow.

The Concept:In an API-led connectivity approach, the "Interface" represents the contract (such as the RAML specification, the HTTP Listener, and the APIkit Router). The "Implementation" represents the backend logic and flows that process the request.

The Flow:

API Client:The consumer (e.g., a mobile app, Postman, or another system) initiates the HTTP request.

API Interface:The request first hits the Interface. This layer defines the URL, validates the request against the API Specification (RAML/OAS), and routes it to the correct flow.

API Implementation:Once validated and routed, the request is processed by the implementation flows (business logic) to fetch data or perform actions.

Therefore, the data travels:Client -> Interface -> Implementation.
