HTTP Status Codes
You send a request to an API. Sometimes everything works: 200 OK Sometimes you made a mistake: 404 Not Found And sometimes the problem isn't yours at all: 500 Internal Server Error These three-digit numbers are HTTP status codes. They are one of the simplest ways for a server to tell a client what happened to its request. But with dozens of possible status codes, do you really need to memorize…
HTTP status codes are three-digit numbers that servers use to communicate the outcome of a client's request. These codes are grouped into five categories: informational (1xx), success (2xx), redirection (3xx), client error (4xx), and server error (5xx). Understanding the most common status codes is crucial for backend developers, as they help identify issues and guide clients accordingly.
Some frequently encountered status codes include 200 OK (successful request), 201 Created (resource created successfully), 204 No Content (success with no response body), redirect codes (301, 302), and common client errors like 400 Bad Request (invalid request) and 404 Not Found (resource not found).
