Explain how to use status codes effectively in a RESTful API.
- Always use the 200 OK status code for every response.
- Use 404 Not Found for all error scenarios.
- Return only 500 Internal Server Error for all errors.
- Choose appropriate status codes to indicate the outcome of the request.
Using status codes effectively in a RESTful API is essential for conveying the outcome of a request to clients. Always using the 200 OK status code for every response is not appropriate; instead, you should choose status codes that accurately represent the result. Similarly, using 404 Not Found for all error scenarios is not ideal because it doesn't provide enough information about the nature of the error. Returning only 500 Internal Server Error for all errors is not recommended as it lacks specificity. The best practice is to choose appropriate status codes such as 200 for successful requests, 201 for resource creation, 204 for successful requests with no response body, 400 for client errors, and 500 for server errors.
