public enum ScraperResultCode
This very special result code may only be returned from Login(JsonObject) or InitiatePayment(SepaDocument, JsonObject), when an additional challenge response value is needed for a successful log on. In response to this result code the client shall obtain the challenge response value from the user and include it with the other credentials in a followup call to Login(JsonObject).
A programmatic failure occured. Maybe missing JSON data or an invalid state for a method call. These should only occur when there is a bug in the calling code.
The scraper implementation encountered some unexpected JSON or HTML content which prevents further processing of the request. Usually this means that the implementation must be fixed.
The given security credentials have been proven wrong. Often this may be the result of a Login(JsonObject) with wrong PIN or password.
