Hi Team,

from CreateEmbededWidget.I have test account ,I can ping with my apikey and send test file also working well.

When i try to create embeded widget using CreateEmbededWiget in SOAP API with my pdf file its giving the following error

" Document Title is required. (apiActionId=XW2L8DU63B5JI48)"

  EmbeddedWidgetCreationResultErrorCode.EXCEPTION

In my code is following,

                apiKey="XXXXXXXXXXXX";

                 ES = new EchoSignDocumentService18();

                Pong pong = ES.testPing(apiKey);

                SenderInfo sender = null;

                WidgetCreationInfo widget = new WidgetCreationInfo();

                FileStream pdfFile = new FileStream(@"D:\test4.pdf", FileMode.Open);

                echosign.secure.com.FileInfo file = new echosign.secure.com.FileInfo("test4.pdf", null, pdfFile);

                echosign.secure.com.FileInfo[] fileSizes = new echosign.secure.com.FileInfo[1];

                fileSizes[0] = file;

                widget.fileInfos = fileSizes;

                EmbeddedWidgetCreationResult embResult = ES.createEmbeddedWidget(apiKey, sender, widget);

                if (embResult.success)

                    return embResult.javascript;

                else if (embResult.errorCodeSpecified)
