Hi Devin,

Thanks for your response! We are sending binary multipart formdata as base64.

I tried using a slightly modified version of your code but got an error. Perhaps, there's something wrong with my version of the code.  Here's what I used:

Here's what the Form Post Activity looks like:

The error states that we have an "InvalidObject"

So I looked into the Token Value returned by from the SDK activity and it's like this. I'm not sure if this looks right. 

Once again, thank you for your help and I'd appreciate any sort of pointers.

Best regards,
Kentaro 

While the DocumentData value looks like it is probably correct, I would change your code to use the Workflow connection.  Then you will not have to deal with logging into the repository.  Also, I would implement "using" blocks in the code to make it cleaner and reduce potential memory leakage.

The code looks something like

            String base64String = null;
            try
            {
                // Get EntryID from the FindEntry activity
                int iDocID = (int)GetTokenValue("FindEntry_OutputEntry_ID");
                // Get the document using the Workflow connection
                using (DocumentInfo DocInfo = Document.GetDocumentInfo(iDocID, RASession))
                {
                    // Create MemoryStream to hold exported document
                    using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
                    {
                        // Create DocumentExporter object
                        DocumentExporter de = new DocumentExporter();
                        // Export to PDF in MemoryStream
                        de.ExportPdf(DocInfo, DocInfo.AllPages, PdfExportOptions.IncludeText, ms);
                        // Write MemoryStream data to Base64 string
                        base64String = Convert.ToBase64String(ms.ToArray());
                    }
                }
            }
            catch (Exception ex)
            {
                // Report exception message
                WorkflowApi.TrackError(ex.Message);
                // Set return value to null
                base64String = null;
            }
            // Return the Base64 String
            SetTokenValue("DocumentData", base64String);
