API Data Flow Diagram Description

This diagram illustrates the validation and processing flow of requests in the API. The process starts when the user attempts to log in. If the credentials are incorrect, the user is prompted to retry. Once successfully authenticated, the system checks if the user is authorized. If the key is invalid or has expired, the request is rejected.

If the user is authorized, the API validates whether the request is well-formed. If it is, a response with status code 200 is returned. This response can be just the 200 code or 200 along with a JSON containing the relevant data, depending on the context of the request. If the request is malformed, the server may respond with error codes such as 400, 422, or 500, depending on the type of issue encountered in the request structure or server processing.
