What does a 2xx HTTP status code indicate?

A 2xx HTTP status code signifies that the request made by the client has been successfully processed by the server. This status category indicates that the action requested by the client was received, understood, and accepted, providing positive confirmation of the operation's success.

For example, a 200 status code means "OK," confirming that the request has succeeded. Other codes in the 2xx range, such as 201 for "Created" when a resource has been successfully generated, or 204 for "No Content" when the request was successful but there is no content to return, further exemplify the successful outcomes associated with this category.

In contrast, the other options refer to different classes of status codes: redirection is typically represented by 3xx codes, unauthorized requests fall under 4xx codes, and client errors also belong to the 4xx range. Therefore, understanding the meaning of a 2xx status code is crucial because it conveys a successful interaction between the client and server.
