Errors

Novant 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, a resource does not exist, etc.). Codes in the 5xx range indicate an error with Novant’s servers (these are rare).

HTTP Status Code	Code Summary
`200 OK`	Everything worked as expected.
`400 Bad Request`	The request was unacceptable, often due to missing a required parameter.
`401 Unauthorized`	No valid API key provided.
`402 Request Failed`	The parameters were valid but the request failed.
`403 Forbidden`	The API key doesn’t have permissions to perform the request.
`404 Not Found`	The requested resource doesn’t exist.
`409 Conflict`	The request conflicts with another request (perhaps due to using the same idempotent key).
`429 Too Many Requests`	Too many requests hit the API too quickly. We recommend an exponential backoff of your requests.
`500, 502, 503, 504`	Something went wrong on Novant’s end. (These are rare.)
