Hi,


Thank you for the code example. I can see that you have missed such declaration:

SignDocument = new SignDocument
{
DocumentGuid = document.Guid,
RecipientGuid = document.SignatureDocumentRecipients.First().Guid
};

Then you should use this object in the Signature method. For example as shown on the screenshot

For more info please check WebForms example from this package

Best regards.
