In which order are the API Client, API implementation, and API Interface components called in a typical REST request?

In a typical REST request, the sequence involves the API Client initiating the interaction by sending a request to the API Interface. The API Interface acts as the entry point for the request and is responsible for processing the request, routing it appropriately, and applying any necessary transformations or validations. Following this, the API Interface forwards the request to the API Implementation, which contains the concrete logic for handling the request and generating the appropriate response.

Thus, the flow begins with the API Client sending a request which reaches the API Interface, and then that interface coordinates with the API Implementation to complete the transaction. This illustrates the layered architecture that characterizes RESTful services, ensuring clear separation of concerns between the client interaction, the interface management, and the backend processing logic.

This correct sequence helps in understanding the interaction and flow of data in REST APIs effectively.
