# Error codes

Check the possible error codes that the PayFit API can return.

### ❌ Error codes

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

In general:

* Codes in the `2xx` range indicate success.
* Codes in the `4xx` range indicate an error that failed given the information provided (e.g., a required parameter was omitted, missing authentication, etc.).
* Codes in the `5xx` range indicate an error within our servers. We will do our best to so that it never happens 😇.
