HTTP HTTP Status Codes Top 10 HTTP Status Code

Example

2xx Success

• 200 OK - Standard response for successful HTTP requests.
• 201 Created - The request has been fulfilled, resulting in the creation of a new resource.
• 204 No Content - The server successfully processed the request and is not returning any content.

3xx Redirection

• 304 Not Modified - Indicates that the resource has not been modified since the version specified by the request headers If-Modified-Since or If-None-Match.

4xx Client Error

• 400 Bad Request - The server cannot or will not process the request due to an apparent client error (e.g., malformed request syntax, too large size, invalid request message framing, or deceptive request routing).
• 401 Unauthorized - Similar to 403 Forbidden, but specifically for use when authentication is required and has failed or has not yet been provided. The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource.
• 403 Forbidden - The request was a valid request, but the server is refusing to respond to it. The user might be logged in but does not have the necessary permissions for the resource.
• 404 Not Found - The requested resource could not be found but may be available in the future. Subsequent requests by the client are permissible.
• 409 Conflict - Indicates that the request could not be processed because of conflict in the request, such as an edit conflict between multiple simultaneous updates.

5xx Server Error

• 500 Internal Server Error - A generic error message, given when an unexpected condition was encountered and no more specific message is suitable.
