Adding a contact to a list in from scratch C#

[RachelE81]

         Please help :(  I tried to do this exactly like the API documentation.... Is there anything im missing or not adding.  I of course get the 400 error.

Thanks

privatevoid btn_ContactEmailSubmit_Click(object sender, EventArgs e)

            {

       if (txtbox_ContactEmail != null)

                {

        string NewListName = txtbox_ContactEmail.Text;

        string Resource = API_RESOURCE_CONTACTS;

        string Url = String.Format("https://api.constantcontact.com/ws/customers/{0}/{1}", API_USERNAME, Resource);

　

CredentialCache CredentialCache = newCredentialCache();

                    CredentialCache.Add(

         newUri(Url), "Basic", newNetworkCredential(API_KEY + "%" + API_USERNAME, API_PASSWORD));

try

                    {

XDocument NewContact = newXDocument

(

 newXDeclaration("1.0", "utf-8", "no"),

 newXElement

   (

       Atom + "entry",

      newXAttribute("xmlns", "http://www.w3.org/2005/Atom"),

newXElement(Atom + "title=\"text\"", "" ),

newXElement(Atom + "updated", "2011-09-02"),

newXElement(Atom + "author", ""),

newXElement(Atom + "id", "data:,none"),

newXElement(Atom + "summary",

           newXAttribute("type=\"text\"", "Contact")),

newXElement(Atom + "content",

           newXAttribute("type", "application/vnd.ctct+xml"),

newXElement(ConstantContact + "Contact",

           newXAttribute("xmlns", "http://ws.constantcontact.com/ns/1.0/"),

newXElement(ConstantContact + "EmailAddress", txtbox_ContactEmail.Text),

newXElement(ConstantContact + "OptInSource", "ACTION_BY_CUSTOMER"),

newXElement(ConstantContact + "ContactLists",

newXElement(ConstantContact + "ContactList", newXAttribute("id", "https://api.constantcontact.com/ws/customers/{myusername}/lists/1"))

                            )

                            )

                            )

                            )

                            );

string Response = NewContact.Post(Url, CredentialCache);

MessageBox.Show("You have successfully created a new Contact!");

                        txtbox_ContactEmail.Clear();

                    }

catch

                    {

MessageBox.Show("An Error has occured!");

                    }

                }

Hey,

Did you make sure that your choosing the Id of the contact and passing it to that URI.  Let me know the email address and the ID so i can test it on my side.

[RachelE81]

CredentialCache LoginCredentials = newCredentialCache();

string ContactURI = String.Format("https://api.constantcontact.com/ws/customers/{0}/{1}/5608", API_USERNAME, API_RESOURCE_CONTACTS);

                        LoginCredentials.Add(

newUri(@"https://api.constantcontact.com/ws/customers/smimarketing"), "Basic", newNetworkCredential(API_KEY + @"%" + API_USERNAME, API_PASSWORD));

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(ContactURI);

                        request.Credentials = LoginCredentials;

                        request.Method =

"PUT";

                        request.ContentType =

@"application/atom+xml";

                        request.ContentLength = byteArray.Length;

Stream dataStream = request.GetRequestStream();

                        dataStream.Write(byteArray, 0, byteArray.Length);

                        dataStream.Close();

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

string returnString = response.StatusCode.ToString();

Console.WriteLine(returnString);

MessageBox.Show("You have successfully updated a Contact!");

Email: hello@hello.com

ID:    5608

List:  28

the current list it is in is 1
