# saveLog() for Lightning Experience

## Usage

Saves or updates an object in Salesforce. This method is available in API version 38.0 or later.

:::note
- To update using this method, include `Id`.
- To create using this method, include `entityApiName`.
- If an object uses `recordType`, pass the `recordTypeId` in the `saveLog` call. If you don't pass the `recordType`, the record is created using the default `recordType` for the profile. To create a person account, you can pass the person account `recordType` if the profile's default is to a business account.
- To refresh after you update or create using this method, call the `refreshView` method in the `callback` method.

## Arguments

| Name       | Type     | Description                                                                                                                                                                                                                               |
| ---------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `value`    | object   | Specifies the fields to save or update on the object. If the object's ID is specified, a record is updated. If the object's ID isn't specified, a new record is created. Ensure all required fields are specified when creating a record. |
| `callback` | function | JavaScript method executed when the API method call is completed.                                                                                                                                                                         |

To update a record, include the object's ID in `value`:

```javascript
{Id:"00QR0000000yN5iMAE", LastName:"New lastname" }
```

To create a record, include `entityApiName` instead:

```javascript
{entityApiName:"Contact", LastName:"LastName" },callback:callback}
```
