# Errors

The Glu API uses standard response codes to indicate a success or failed API request.  A successful request will use a `2XX` range of response codes, `4XX`  indicates an error with the provided information and a `5XX` range error code indicates an error at our end.

You can check the response body for a more detailed explaination of an error, the error content type will use the application/problem+json standard.
