# updateCustomer

### Update the customer's attributes

```swift
/**
 * Update existing customer.
 *
 * @param customer - Customer with all fields that needs to be updated. All customer fields except 'username', 'password' and 'lock' can be updated with this method.
 * @param onSuccess - invoked if customer successfully updated
 * @param onError - invoked if exception occurred
 *
 */
- (void) updateCustomer: (Customer*) customer
              onSuccess: (void (^)(BOOL)) onSuccess
                onError: (void (^)(NSError *error)) onError NS_SWIFT_NAME( updateCustomer(_:onSuccess:onError:) );
```

The attributes:

`username`, `password`, `lock`

are not available in customer update.

The function updates the customer created with functions `createCustomer,` `setupCustomer` and `getCustomerInfo.`
