I tried to add multiple contacts to my contact list using the example provided in the Bulk Activities. The code i use is given below. I get the Error "WebException: ProtocolErrorWith response: The remote server returned an error: (415) Unsupported Media Type." Can you please help me on how to add multiple contacts to a contact a list on a single invocation? Can you point out what is the error in the code given below?
public string Bulk_POST(string APIKey, string username, string password)
{
// Create login credentials
CredentialCache LoginCredentials = new CredentialCache();
// Create a new credential for this account
LoginCredentials.Add(new Uri("https://api.constantcontact.com/ws/customers/USERNAME" + username), "Basic", new NetworkCredential(APIKey + '%' + username, password));
// Create a web request
HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://api.constantcontact.com/ws/customers/" + username + "/contacts");
// Set Request to be a POST
Request.Method = "POST";
// Set the ContentType property.
Request.ContentType = "application/x-www-form-urlencoded";
// Set Request credentials
Request.Credentials = LoginCredentials;
// Set up XML String for the POST
string XMLData = "activityType=ADD_CONTACTS"+
"&data=Email+Address%2CFirst+Name%2CLast+Name%0A"+
"wstest3%40example.com%2C+Fred%2C+Test%0A"+
"wstest4%40example.com%2C+Joan%2C+Test%0A"+
"wstest5%40example.com%2C+Ann%2C+Test"+ "&lists=http%3A%2F%2Fapi.constantcontact.com%2Fws%2Fcustomers%2Fmyusername%2Flists%2F5"+
"&lists=http%3A%2F%2Fapi.constantcontact.com%2Fws%2Fcustomers%2Fmyusername%2Flists%2F6";
// Convert XMLData to byteArray for posting
byte[] byteArray = Encoding.UTF8.GetBytes(XMLData);
// Send POST request
try
{
// Set the ContentLength portion of the header
Request.ContentLength = byteArray.Length;
string XMLResponse = "Bytes to send: " + byteArray.Length;
// Create a stream for the POST Request // Note: Remember to add using System.IO
Stream streamRequest = Request.GetRequestStream();
// Write the data to the stream.
streamRequest.Write(byteArray, 0, byteArray.Length);
streamRequest.Close();
HttpWebResponse Response = (HttpWebResponse)Request.GetResponse();
// Process the Response as needed
// This is a generic StreamReader to read the entire response in
// You can recast this as any type of stream derivative
StreamReader Reader = new StreamReader(Response.GetResponseStream());
// Read the entire XML response to a string
// Note there may not be a XML response for a successful POST
XMLResponse += Response.StatusCode + Response.StatusDescription + Reader.ReadToEnd();
// Close Reader
Reader.Close();
// Close the response to free up the system resources
Response.Close();
return XMLResponse;
}
catch (WebException e)
{
// Get the web exception type and response code
return ("WebException: " + e.Status + "With response: " + e.Message);
}
catch (Exception e)
{
// Get the exception type
return ("Exception: " + e.Message);
}
}
}
