Error Response Format

Every non-2xx response returns a JSON object with the same two fields.

Field	Type	Description
message	String	Human-readable description of what went wrong
name	String	Error class name, for branching in client code

{
  "message": "Not found",
  "name": "ItemNotFoundException"
}

Common name values

name	Status	Meaning
MissingParamsError	422	A required parameter is missing
ValidationError	422	Parameter content failed validation
AuthenticationError	401	Authentication failed
UnauthorizedError	403	Access denied
ItemNotFoundException	404	Resource not found
ItemExistsException	409	Resource already exists
QuotaExceededError	402	Plan quota exceeded
ConfigurationError	503	Service temporarily unavailable

Errors outside this list are returned as 500 with the same body shape.

See Error Code for the status codes themselves.
