While that list is handy for sure, the OP&#x27;s site also enables you to actually get the HTTP status code of your desires, since you can specify it in the request URL path: <a href="http:&#x2F;&#x2F;codes.io&#x2F;304" rel="nofollow">http:&#x2F;&#x2F;codes.io&#x2F;304</a>. This will return a `304 Not Modified` response, which can be helpful in writing testcode for your API service.
