Our API uses standard HTTP response codes to indicate whether a specific request has been successfully completed or not.

Error Code	Reason
200 OK	The request has succeeded.
400 Bad Request	The server could not understand the request due to invalid syntax.
401 Unauthenticated	The client must authenticate itself to get the requested response.
429 Too Many Requests	The user has sent too many requests in a given amount of time. We recommend to implement exponential back-off.
500, 501, 502, 503 Service Unavailable	The server is not able to handle the request. This can be because our servers are down for maintenance or they are overloaded.
