How do I set the FromFile option on a capture field

Found the problem that caused the error. In the sandbox environment I had to call "WithHandOverLinkHref" on the DocumentPackageSettingsBuilder with a URL.

Hi robadmiraal,

Thanks for your post!

Yes, I believe fromfile is not yet supported by text tags. Therefore, try to update the signatures in a separate step:

            DocumentPackage documentPackage = PackageBuilder.NewPackageNamed("Test FromFile")
                             .WithSigner(SignerBuilder.NewSignerWithEmail("[email protected]")
                                           .WithCustomId("Signer1")
                                           .WithFirstName("John")
                                           .WithLastName("Smith"))
                             .WithDocument(DocumentBuilder.NewDocumentNamed("Document1")
                                     .WithId("Document1")
                                     .FromFile("C:\\Users\\liangdu1\\Desktop\\work\\documents\\demo docs\\4B-CarLoan.pdf")
                                     .WithSignature(SignatureBuilder.CaptureFor("[email protected]")
                                         .OnPage(0)
                                         .AtPosition(100, 140)
                                      )
                                    .WithSignature(SignatureBuilder.CaptureFor("[email protected]")
                                         .OnPage(0)
                                         .AtPosition(100, 240)
                                      )
                                    .WithSignature(SignatureBuilder.CaptureFor("[email protected]")
                                         .OnPage(0)
                                         .AtPosition(100, 340)
                                      )
                              )
                              .Build();

            PackageId packageId = ossClient.CreatePackageOneStep(documentPackage);

            DocumentPackage createdPackage = ossClient.GetPackage(packageId);
            foreach (var doc in createdPackage.Documents)
            {
                if (doc.Id == "Document1")
                {
                    List<Signature> captureSignatures = new List<Signature>();
                    foreach (var signature in doc.Signatures)
                    {
                        if (signature.Style == SignatureStyle.HAND_DRAWN)
                        {
                            signature.FromFile = true;
                            captureSignatures.Add(signature);
                        }
                    }

                    if (captureSignatures.Count > 0)
                    {
                        ossClient.ApprovalService.UpdateApprovals(createdPackage, doc.Id, captureSignatures);
                    }
                }
            }

            ossClient.SendPackage(packageId);
            Debug.WriteLine(packageId);

Let me know how this works for you.

Thank you very much for this solution. Unfortunately I get an error on this line:

DocumentPackage createdPackage = ossClient.GetPackage(packageId);

The error is: :

OneSpanSign.Sdk.OssException: 'href cannot be null or an empty string'

packageId is filled and the package is created.

The baseURI on the ossCLient is "https://sandbox.esignlive.com/api". Can you help me with this?

The problem only occurs in the sandbox. In the live API it works well.

Another thing in your example code is that it includes this line:

ossClient.SendPackage(packageId);

Causing the package to be sent out immediately. I've changed it to:

ossClient.UpdatePackage(packageId, createdPackage);

So the package is only updated and not send to the signers.
