HTTP Response Status Codes: Successful (200–299) — Grow Together By Sharing Knowledge

HTTP response status codes are an essential part of web communication, providing valuable information about the outcome of a client’s request.

In our previous blog posts, we explored Informational Responses (100–199) and learned how they establish communication and signal the progress of a request.

Now, let’s dive into the second class of HTTP response status codes — Successful Responses (200–299). These codes indicate that the client’s request was successfully received, understood, and accepted by the server. Join us as we explore each of these successful responses in detail.

Table: HTTP Response Status Codes — Successful Responses HTTP 2xx Status Codes (Successful Responses)

200 OK

• Description: The request was successful, and the server sends the requested data in the response body.
• Example: HTTP/1.1 200 OK

201 Created

• Description: The request was successful, and the server has created a new resource as a result.
• Example: HTTP/1.1 201 Created

202 Accepted

• Description: The server has accepted the request for processing, but the processing is not yet complete.
• Example: HTTP/1.1 202 Accepted

203 Non-Authoritative Information

• Description: The server successfully processed the request, but the returned information may be from a different source.
• Example: HTTP/1.1 203 Non-Authoritative Information

204 No Content

• Description: The request was successful, but there is no data to return (e.g., for DELETE requests).
• Example: HTTP/1.1 204 No Content

205 Reset Content

• Description: The server instructs the client to reset the document view, which is often used after form submissions.
• Example: HTTP/1.1 205 Reset Content

206 Partial Content

• Description: The server successfully fulfilled a partial GET request, returning only a portion of the requested data.
• Example: HTTP/1.1 206 Partial Content

207 Multi-Status

• Description: The server has completed a multi-status response, providing information about multiple independent operations.
• Example: HTTP/1.1 207 Multi-Status

• Example: HTTP/1.1 208 Already Reported

226 IM Used

• Description: The server successfully fulfilled a request for the resource, and the response is a representation of the result of one or more instance manipulations applied to the current instance.
• Example: HTTP/1.1 226 IM Used

Successful responses (status codes 200–299) indicate that the client’s request was successfully received, understood, and processed by the server. These codes are crucial for indicating the positive outcome of various types of requests, such as data retrieval, resource creation, and more.

As a developer, understanding these successful response codes helps in handling successful requests appropriately, interpreting returned data, and ensuring a smooth user experience.

Next, we’ll delve into the world of Redirection Responses (300–399), which signal that further action is needed to complete the request. Happy coding!
