What are the primary status codes for successful API responses?

• A. 400 Bad Request, 404 Not Found
• B. 200 OK, 201 Created
• C. 500 Internal Server Error, 401 Unauthorized
• D. 300 Multiple Choices, 302 Found

Answer: (B)

The primary status codes indicating successful API responses are 200 OK and 201 Created. A status code of 200 OK signifies that the request was successfully received, understood, and processed by the server. This is the most common response for successful GET requests, indicating that the server has returned the requested data without any issues. On the other hand, a status code of 201 Created is used to indicate that a request, typically a POST request, has been fulfilled and has resulted in the creation of a new resource. This response not only acknowledges the success of the request but also indicates the creation of a resource, often accompanied by a URI in the response header pointing to the newly created resource. These codes are essential for developers as they convey clear and unambiguous information about the result of the API call, which is crucial for implementing proper error handling and success confirmation in API interactions.
