The following is an example of updating a Contact where we are changing only the email address. (See [Contact](docId:3GJo07dAqjxtJeAYY3sl9) for all available fields).  The NetSuite contact Id (internalId) is required to update the contact.

:::hint{type="info"}
Note: You can only update one record at a time.

The response returns the complete contact information, but we have shortened the response in our example for ease of reading.

Request

```apex
//  Create a Map to store all the data of a Contact
Map<String, Object> nsContact = new Map<String, Object>();

//Pass internalId to update the Contact
    nsContact.put('internalId', '63547');
    nsContact.put('email', 'jamesupdate@grandhotel.com');

//  Initializing the RequestJSON Data to be passed.
Map<String, Object> requestJSONMap = new Map<String, Object>();
    requestJSONMap.put('contacts', new List<Object>{nsContact});
    String reqJSON = JSON.serialize(requestJSONMap);

Map<String, Object> reqObj = new Map<String, Object>();
    reqObj.put('version', '1.0');
    reqObj.put('action', 'updateContact');
    reqObj.put('requestJSON', reqJSON);

//  Placing a request to Breadwinner Global API
Map<String, Object> resp = breadwinner_ns.BreadwinnerNetSuiteAPI.call(reqObj);
System.debug(resp);
