Understanding HTTP status codes

HTTP status codes are three-digit numbers sent by a server in response to an HTTP request. These codes provide feedback to the client about the outcome of the request and help identify any issues that may have occurred during the transaction. The first digit of an HTTP status code indicates the category of the responses, which could be Informational, Successful, Redirection, Client Error, or Server Error.

The common status codes you’ll encounter for each category are listed as follows:

1XX Informational

Status Code	Description	Reason
