Docusign - Error opening PDF downloaded through the Rest API

Question

With the REST api, I am trying to get the documents out of a completed envelope. My header is using X-DocuSign-Authentication.

EnvelopesApi ap = new EnvelopesApi();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");

EnvelopeDocumentsResult edr = ap.ListDocuments((AccountId, "xxx-xx-xxx");

List<EnvelopeDocument> docs = edr.EnvelopeDocuments;

foreach(EnvelopeDocument doc in docs)
{  
   Stream stream1 = ap.GetDocument(AccountId, "xxx-xx-xxx", doc.DocumentId);
   StreamReader reader = new System.IO.StreamReader(stream1, encode);
   var data = reader.ReadToEnd();
   StreamWriter writer = new StreamWriter(@"C:\mysigneddoc.pdf");
   writer.Write(data);
   writer.Close();
}

When I try to open the completed pdf, I get the error stating that

the signers identity has not been verified.

Any ideas where I might be going wrong?

Please look at the API recipe here to download the documents from an envelope.

var ap = new EnvelopesApi();
var edr = ap.ListDocuments((AccountId, "xxx-xx-xxx");
List<EnvelopeDocument> docs = edr.EnvelopeDocuments;

foreach(EnvelopeDocument doc in docs)
{
  // GetDocument() API call returns a MemoryStream
  var docStream = (MemoryStream)envelopesApi.GetDocument(accountId, envelopeId, doc.DocumentId);
  // let's save the document to local file system
  filePath = @"C:\temp\" + Path.GetRandomFileName() + ".pdf";
  fs = new FileStream(filePath, FileMode.Create);
  docStream.Seek(0, SeekOrigin.Begin);
  docStream.CopyTo(fs);
  fs.Close();
}

You can also download the combined documents in an envelope using the GetEnvelopeDocuments api. You are not required to query for each individual document.

Combined PDF

Pass the string combined as the documentId.

Retrieve a PDF that contains the combined content of all documents and the certificate.

string envelopeId = "XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
string accountId = "XXXXXX";
var envApi = new EnvelopesApi();

// GetDocument() API call returns a MemoryStream
var docStream = (MemoryStream)envApi.GetDocument(accountId, envelopeId, "combined");
// let's save the document to local file system
string filePath = @"C:\temp\" + Path.GetRandomFileName() + ".pdf";
var fs = new FileStream(filePath, FileMode.Create);
docStream.Seek(0, SeekOrigin.Begin);
docStream.CopyTo(fs);
fs.Close();

ZIP file

Pass the string archive as documentId

Retrieve a ZIP archive that contains all of the PDF documents, the certificate, and any .WAV files used for voice authentication.

var envApi = new EnvelopesApi();

// GetDocument() API call returns a MemoryStream
var docStream = (FileStream)envApi.GetDocument(accountId, envelopeId, "archive");
// let's save the document to local file system
string filePath = @"C:\temp\" + Path.GetRandomFileName() + ".zip";
var fs = new FileStream(filePath, FileMode.Create);
docStream.Seek(0, SeekOrigin.Begin);
docStream.CopyTo(fs);
fs.Close();
