Currently although the reason for refusal is requested when not signing a document, then this value is not available for use anywhere. ValidateID does have this option available (Signers.RejectionReason from "Operation Get Document Information"). It would be very useful to implement the option to collect this information as otherwise you have to go and ask the person who has refused to sign the document to find out the reason for the rejection.
