# Errors

Patch APIs uses conventional HTTP response codes to indicate the success or failure of an API request.

As a general rule:

* Codes in the `2xx` range indicate success
* Codes in the `4xx` range indicate incorrect or incomplete requests, like invalid paths, incorrect auth, or incorrect parameters for the request.
* Codes in the `5xx` range indicate an error in the server.
