# 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.
## Syntax
```javascript
sforce.opencti.saveLog({
value:{
entityApiName:STRING, //Optional
Id:STRING, //Optional
param:VALUE //Optional
},
callback:FUNCTION //Optional
})
```
## 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}
```

## Response
This method is asynchronous. The response is returned in an object passed to a callback method. The response object contains the following fields.

|------|------|-------------|
|`success`|boolean|Returns `true` if the API method call was invoked successfully, `false` otherwise.|
|`returnValue`|object|ID of object if creating or updating the object was successful; `null` if creating or updating the object wasn't successful.|
|`errors`|array|If the API call was successful, this variable is `null`. If the API call failed, this variable returns an array of [error messages](https://developer.salesforce.com/docs/service/api-cti/guide/sforce-api-cti-error-messages-lightning.md).|
