# Errors

Wundaflow uses standard HTTP response codes to indicate success or failure of an API request. Generally, codes in the `2xx` range indicate success, codes in `4xx` range indicate an error that failed due to the request params, and codes in the `5xx` range indicate an error with Wundaflow's platform.

Most `4xx` error codes will also return a JSON response body that indicates the exact issue with the request.
