## Sync configuration

Once you've set up your LINE Ads destination and have a [model](https://docs.hightouch.com/getting-started/concepts.md#models) to pull data from, you can set up your sync configuration to begin syncing data. Go to the [**Syncs** overview page](https://app.hightouch.com/syncs?from=docs) and click the **Add sync** button to begin. Then, select the relevant model and the LINE Ads destination you want to sync to.

### Syncing segments

Sync data from any source to LINE Ads custom audiences.

#### Record matching

To match rows from your model to segment in LINE Ads, you need to select a model column and corresponding LINE Ads field. You can match on any of the following LINE Ads fields:

* **Email**
* **Phone number**
* **IFA**

If you are syncing to an existing segment, only the ID type for that segment is available.

## Tips and troubleshooting

To see the exact API requests and responses from each sync run, use the [live debugger](https://docs.hightouch.com/syncs/debugger.md). To get notified by Slack, PagerDuty, SMS, or email when a sync fails, set up [sync alerts](https://docs.hightouch.com/syncs/alerting.md). If you run into an issue this page doesn't cover, [contact support](#pylon-chat).
