The following is an example of update Customer. The QuickBooks customer Id (Id) is required to update the customer (See [Customer](docId\:BEUVWRPdRH8smtNBYnEnJ) for the available fields).

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

- When you want to update specific fields of an entity without affecting others, use a sparse update operation by setting sparse= 'true' in your request. This approach is more efficient and less prone to unintended changes than a full update.

Request

```apex
//  Create a Map to store all the data of a Customer
Map<String, Object> customerMap = new Map<String, Object>(); 
    customerMap.put('DisplayName','Weiskopf Consulting');
	customerMap.put('Id','1201');
	customerMap.put('SyncToken','0');

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

Map<String, Object> reqObj = new Map<String, Object>();
    reqObj.put('version', '1.0');
    reqObj.put('action', 'updateCustomer');
    reqObj.put('requestJSON', reqJSON);
    //Required, if QuickBooks Multi-Org is enabled in Breadwinner. 
    reqObj.put('qbOrgId', '4620816365285051610');

//  Placing a request to Breadwinner Global API
Map<String, Object> respMap = breadwinner_qbo.BreadwinnerQBAPI.call(reqObj);
System.debug(respMap);
