For example, 200 Ok means that nothing went wrong and a GET or POST request was successful. 201 Created means that a GET or POST request has been fulfilled and a new resource has been created for the client. 202 Accepted means that a request has been accepted and is now being processed. 204 No Content means that there is no content coming back from the server (very similar to 200). 206 Partial Content is usually used for paginated responses indicating there is more data to follow.
