## Connect to Kayzen

Go to the [**Destinations** overview page](https://app.hightouch.com/destinations?from=docs) and click the **Add destination** button. Select **Kayzen** and click **Continue**. You can then authenticate Hightouch to **Kayzen**.

Enter the following fields into Hightouch:

* **API key**

## Sync configuration

Once you've set up your Kayzen 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 Kayzen destination you want to sync to.

### Syncing audiences

Sync data from any source to Kayzen audiences.

#### Select an existing audience or create a new one

You can create a new audience or sync to an existing one. When creating a new audience, you can optionally enter a name. If you leave it blank, Hightouch uses the name of the model. To use an existing audience, select it from the dropdown.

Hightouch creates the audience in Kayzen during the first sync run.

#### Record matching

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

* **IDFA**
* **GAID**

#### Field mapping

Hightouch lets you sync audience fields via [field mapping](https://docs.hightouch.com/syncs/mapping-data.md).
You can map data from any of your model columns to the default audience fields.
Ensure your model's columns have the same data types as the fields you want to sync to.

## 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).
