Hi Guys,
I'm adding contacts to the lists thru activities. I'm getting The remote server returned an error: (400) Bad Request. Code is as follows
HttpWebRequest oRequest = null;
oRequest = (HttpWebRequest)LoginCredReq("https://api.constantcontact.com/ws/customers/username/activities");
oRequest.ContentType = "multipart/form-data; boundary=" + PostData.boundary;
oRequest.Method = "POST";
PostData pData = new PostData();
Encoding encoding = Encoding.UTF8;
Stream oStream = null;
pData.Params.Add(new PostDataParam("activityType", "SV_ADD", PostDataParamType.Field));
pData.Params.Add(new PostDataParam("lists", "http://api.constantcontact.com/ws/customers/username/lists/1", PostDataParamType.Field));
pData.Params.Add(new PostDataParam("data", "C:\\test.xls","file", PostDataParamType.File));
byte[] buffer = encoding.GetBytes(pData.GetPostData());
oRequest.ContentLength = buffer.Length;
oStream = oRequest.GetRequestStream();
oStream.Write(buffer, 0, buffer.Length);
oStream.Close();
HttpWebResponse oResponse = (HttpWebResponse)oRequest.GetResponse();
private WebRequest LoginCredReq(string sUri)
{
CredentialCache LoginCredentials = new CredentialCache();
new NetworkCredential("apikey%username", "password"));
// Create WebRequest, this is a factory class with a static constructor
// You can not use new, all requests must be created with WebRequest.Create
WebRequest Request = WebRequest.Create(sUri); // URI for the GET
// Set Request credentials
Request.Credentials = LoginCredentials;
return Request;
}
