Error Codes

If an API request fails, an HTTP Status code will be returned in the response. Possible error codes are described below:

Code	Reason
`400`	The request is invalid (e.g., required request parameters are not present)
`401`	The requestor could not be authenticated, likely because the required authentication JWT was not provided or is invalid or expired
`403`	The requestor is not authorized to perform the requested operation
`404`	The requested resource was not found. E.g., an attempt was made to update or delete a non-existent subscription
`409`	The requested resource already exists. E.g., an attempt was made to establish a notifications subscription when an identical subscription already exists
`500`	The request failed due to a server error
`504`	The request to the server timed out
