An error response indicating that WingCash requires a valid ReCAPTCHA response for an API call, but the ReCAPTCHA response was not provided, or it failed validation.

Some WingCash API calls rely on an invisible ReCAPTCHA widget to inhibit computers trying to guess passwords or authentication codes. When your app receives this error, your app should execute the invisible ReCAPTCHA widget and automatically resubmit the API call with the ReCAPTCHA response. Note that the invisible widget may open a question and answer session in your app if the ReCAPTCHA servers detect possible abuse.
