Replaces the contact information with information from the specified Contact object. Uninitialized properties are cleared.
First, you usually call Contact_Load to get a contact by its ID, change some of its properties and then pass the updated object to Contacts_Update.
Requirements
The authenticating user must belong to a user group that has the Update privilege for Contacts.
Parameters
The operation uses the following parameters:
AuthenticationData : AuthenticationData, required
An AuthenticationData object containing the login information and the project ID that contains the contact.
Contact : Contact, required
A Contact object with the updated contact information.
SendEmailAlert : string, required
Y means send an email alert to the subscribed users after updating the contact.
Any other value (for example, N or empty string) means do not send e-mail alerts.
Result
None.
Remarks
The Contact object has matching Id and Name properties, for example, AssigneeUserId and AssignedToName. To set them, specify the value only for the Id property. The corresponding Name property will be set automatically.
Example

Sample Code
C#
string login = "[email protected]";
string password = "p@ssword";
int projID = 10372;
// The ID of the contact to update
int id = 4;
								ServiceSoapClient service = new ServiceSoapClient();
// Prepare AuthenticationData
								LoginInfo loginInfo = service.GetLoginInfo("", login, password);
								AuthenticationData authData = new AuthenticationData();
								authData.AppCode = loginInfo.AppCode;
								authData.UserId = loginInfo.UserId;
								authData.PassCode = password;
								authData.DeptId = loginInfo.DeptId;
								authData.ProjId = projID;
// Get a contact by its ID
								Contact contact = service.Contacts_Load(authData, id);
// Change contact properties
								contact.Status = "Closed";
								contact.FolderId = 24;
// Upload the updated contact
								service.Contacts_Update(authData, contact, "N");
								Console.WriteLine("The contact was updated.");
							
Java
String login = "[email protected]";
String password = "p@ssword";
int projID = 10372;
// The ID of the  contact to update
int id = 4;
								ServiceSoap service = new Service().getServiceSoap12();
// Prepare AuthenticationData
								LoginInfo loginInfo = service.getLoginInfo("", login, password);
								AuthenticationData authData = new AuthenticationData();
								authData.setAppCode(loginInfo.getAppCode());
								authData.setUserId(loginInfo.getUserId());
								authData.setPassCode(password);
								authData.setDeptId(loginInfo.getDeptId());
								authData.setProjId(projID);
// Get a contact by its ID
								Contact contact = service.contactsLoad(authData, id);
// Change contact properties
								contact.setStatus("Closed");
								contact.setFolderId(24);
// Upload the updated contact
								service.contactsUpdate(authData, contact, "N");
								System.out.println("The contact was updated.");
