We are using 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, a charge failed, etc.). Codes in the 5xx range indicate an error with WATI servers (these are rare).

401 No valid API key provided.
403 The API key doesn't have permissions to perform the request.
404 The requested resource doesn't exist.
500 Something went wrong on our end. (These are rare.)
