The APIs return HTTP code to indicate success or error on a request. We usually return 200 on any success request and you should be especially careful on 4xx or 5xx response code.

Response Code	Description
200	OK
400	Bad Request \| Probably malformed data
401	Unauthorized \| `access_token` not authorized or missing
403	Forbidden \| This resource can't be access with this `access_token`
404	Not Found \| The requested resource was not found
405	Method Not Allowed \| The resource does not accept this HTTP method
500	Generic Server error \| Something went wrong with our service, contact the support for more informations
502, 503	Bad Gateway \| Most likely a momentary operational error, the requests should be retried
