Why would you need HTTP Code Tool?
When testing APIs or web services, it is essential to verify that the expected HTTP status codes are returned for different scenarios. By utilizing the links provided on this page, you can easily simulate specific HTTP status codes and observe how your application responds to them.
For example, let's say you want to test how your application handles a "404 - Not Found" response. Simply click on the corresponding link ("/return-http-404-code"), and your application will receive a simulated "404" response from the server. This allows you to evaluate if your application gracefully handles such situations, displays appropriate error messages, or performs any necessary error handling logic.
Likewise, you can use other links to simulate various status codes such as "200 - OK," "500 - Internal Server Error," or even less common ones like "418 - I'm a teapot." This level of control enables you to thoroughly test your API or web service's behavior under different conditions, ensuring that it responds accurately and handles errors gracefully.
By leveraging the provided links to simulate different HTTP status codes, you can streamline your testing process, validate your application's response handling, and enhance the overall reliability and robustness of your API or web service.

HTTP Status Codes Explained
HTTP (Hypertext Transfer Protocol) status codes are standard response codes that indicate the status of a request made by a client to a server. These status codes are a crucial part of the communication between web browsers, servers, and other web applications. Understanding HTTP status codes is essential for web developers, system administrators, and anyone working with web technologies.
What is an HTTP Status Code?
HTTP status codes are three-digit numbers that categorize and provide information about the response from the server. They are grouped into five classes, each representing a different category of status codes. The status codes provide valuable insights into the success or failure of a request and assist in troubleshooting and debugging web applications.
The Five Classes of HTTP Status Codes
- Informational (1xx): These status codes indicate that the server has received the request and is processing it.
- Successful (2xx): These status codes indicate that the request was successful and the server has fulfilled it.
- Redirection (3xx): These status codes inform the client that further action is required to complete the request. The client is typically redirected to a different resource or URL.
- Client Errors (4xx): These status codes indicate that there was an error on the client's side, such as an invalid request or unauthorized access.
- Server Errors (5xx): These status codes indicate that there was an error on the server's side while processing the request.
