SDK code for creating Notary transactions and adding Notary related fields.

The attachment is a working example I created for you, using .NET SDK and REST method(for second step). Simply adjust to your own info, and do remember to modify the notary field name if your setup in account was different from my test account. Regarding how to add notary fields, Here's a example of how notary regular and seal fields look like in JSON:

{
              "binding": null,
              "validation": null,
              "id": "cggVvdrOuhAO",
              "page": 0,
              "subtype": "CUSTOMFIELD",
              "extract": false,
              "width": 165,
              "height": 37,
              "formattedValue": "",
              "left": 315,
              "top": 310,
              "extractAnchor": null,
              "data": null,
              "type": "INPUT",
              "value": null,
              "name": "NotaryLicenseExpiryDate"
            },
            {
              "binding": null,
              "validation": null,
              "id": "CYJyVpplmcg7",
              "page": 0,
              "subtype": "SEAL",
              "extract": false,
              "width": 165,
              "height": 37,
              "formattedValue": "",
              "left": 315,
              "top": 404,
              "extractAnchor": null,
              "data": null,
              "type": "INPUT",
              "value": null,
              "name": "NotaryName"
            }

REGULAR notary field has a type of "INPUT", subtype of "CUSTOMFIELD" and use name to identify which field to choose SEAL notary field has a type of "INPUT", subtype of "SEAL" and use name to identify which field to choose So an equivalent .Net code can be:

                Signature notarySignature = SignatureBuilder.SignatureFor(notaryEmail)
                         .AtPosition(400, 100)
                         .WithField(FieldBuilder.CustomField("NotaryLicenseExpiryDate")
                             .WithStyle(FieldStyle.UNBOUND_CUSTOM_FIELD)
                             .AtPosition(400,200)
                             )
                          .WithField(FieldBuilder.CustomField("NotaryName")
                             .WithStyle(FieldStyle.SEAL)
                             .AtPosition(400, 300)
                          )
                         .Build();
                eslClient.ApprovalService.AddApproval(eslClient.GetPackage(createPackageOneStep), notaryDocumentId, notarySignature);

Hope this could help! Duo
