Error Handling: HTTP Status Codes
Map HTTP status codes to user-facing messages, distinguish between network errors and server errors, and implement retry logic.
HTTP Status Code Categories
Status codes are grouped by first digit: 2xx success, 3xx redirect, 4xx client error (your fault), 5xx server error (their fault).
Common 2xx Codes
200 OK: success with body. 201 Created: resource created (often returns the new resource). 204 No Content: success with no body (DELETE, sometimes PUT).
