Which HTTP status code is returned after a successful REST API request? After a successful REST API request, the HTTP status code returned is typically "200 OK." The "200 OK" status code indicates that the request has been successfully processed, and the response body usually contains the requested data or confirms the success of the operation.
Beyond the generic 200 OK status code, REST APIs may also provide more specific status codes to convey additional information about the nature of the success. For example, a status code of 201 Created might be returned after a successful POST request, indicating that the requested resource has been successfully created on the server. Similarly, a status code of 204 No Content may be returned for a successful request that doesn't require the server to send back a response body. These specific status codes offer clients more nuanced information about the outcome of their requests, helping them understand the server's actions in greater detail.
In addition to the HTTP status code, the response headers and body often contain valuable information such as metadata, caching directives, and links to related resources. Properly handling these responses in client applications is crucial for effective communication between clients and servers in a RESTful architecture, ensuring that both parties have a clear understanding of the success and specifics of the API interactions. Overall, the use of appropriate HTTP status codes enhances the robustness and clarity of RESTful API implementations.
