# API errors

Typesense API uses standard HTTP response codes to indicate the success or failure of a request.

Codes in the 2xx range indicate success, codes in the 4xx range indicate an error given the information provided (e.g. a required parameter was omitted), and codes in the 5xx range indicate an error with the Typesense service itself.

401 Unauthorized - Your API key is wrong.
404 Not Found - The requested resource is not found.
409 Conflict - When a resource already exists.
