Can Field locators be used with the CoSign Signature Soap API C# - cosign-api

Question

I have tried
Req.OptionalInputs.FieldLocatorOpeningPattern = "<<";
Req.OptionalInputs.FieldLocatorClosingPattern = ">>";
but sign is not replaced the space provided in pdf. Can you please provide a code sample for using the Soap API.

Answer 1

Please see the code sample below for using CoSign Signature SOAP API (aka SAPIWS) with CoSign Signature Locators:
public SAPISigFieldSettingsType[] getSigFieldLocatorsInPDF(
string FileName,
string UserName,
string Password)
{
//Create Request object contains signature parameters
RequestBaseType Req = new RequestBaseType();
Req.OptionalInputs = new RequestBaseTypeOptionalInputs();
//Here Operation Type is set: enum-field-locators
Req.OptionalInputs.SignatureType = SignatureTypeFieldLocators;
//Configure Create and Sign operation parameters:
Req.OptionalInputs.ClaimedIdentity = new ClaimedIdentity();
Req.OptionalInputs.ClaimedIdentity.Name = new NameIdentifierType();
Req.OptionalInputs.ClaimedIdentity.Name.Value = UserName; //User Name
Req.OptionalInputs.ClaimedIdentity.Name.NameQualifier = " "; //Domain (relevant for Active Directory environment only)
Req.OptionalInputs.ClaimedIdentity.SupportingInfo = new CoSignAuthDataType();
Req.OptionalInputs.ClaimedIdentity.SupportingInfo.LogonPassword = Password; //User Password
Req.OptionalInputs.FieldLocatorOpeningPattern = "<<";
Req.OptionalInputs.FieldLocatorClosingPattern = ">>";
//Set Session ID
Req.RequestID = Guid.NewGuid().ToString();
//Prepare the Data to be signed
DocumentType doc1 = new DocumentType();
DocumentTypeBase64Data b64data = new DocumentTypeBase64Data();
Req.InputDocuments = new RequestBaseTypeInputDocuments();
Req.InputDocuments.Items = new object[1];
b64data.MimeType = "application/pdf"; //Can also be: application/msword, image/tiff, pplication/octet-string
Req.OptionalInputs.ReturnPDFTailOnlySpecified = true;
Req.OptionalInputs.ReturnPDFTailOnly = false;
b64data.Value = ReadFile(FileName, true); //Read the file to the Bytes Array
doc1.Item = b64data;
Req.InputDocuments.Items[0] = doc1;
//Call sign service
ResponseBaseType Resp = null;
try
{
// Create the Web Service client object
DSS service = new DSS();
service.Url = "https://prime.cosigntrial.com:8080/sapiws/dss.asmx"; //This url is constant and shouldn't be changed
SignRequest sreq = new SignRequest();
sreq.InputDocuments = Req.InputDocuments;
sreq.OptionalInputs = Req.OptionalInputs;
//Perform Signature operation
Resp = service.DssSign(sreq);
if (Resp.Result.ResultMajor != Success )
{
MessageBox.Show("Error: " + Resp.Result.ResultMajor + " " +
Resp.Result.ResultMinor + " " +
Resp.Result.ResultMessage.Value, "Error");
return null;
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Error");
if (ex is WebException)
{
WebException we = ex as WebException;
WebResponse webResponse = we.Response;
if (webResponse != null)
MessageBox.Show(we.Response.ToString(), "Web Response");
}
return null;
}
//Handle Reply
DssSignResult sResp = (DssSignResult) Resp;
return Resp.OptionalOutputs.SAPISeveralSigFieldSettings;
}
