## Supported syncing

| Sync Type | Description | Supported Sync Modes | API Reference |
| - | - | - | - |
| **Attribute Lists** | Sync data from any source to VWO Attribute Lists | Insert, Update, Upsert | [Attributes](https://help.vwo.com/hc/en-us/articles/8681465703705-Working-With-Attributes-in-VWO) and [Attribute Lists](https://help.vwo.com/hc/en-us/articles/900003106343-Targeting-Visitors-Using-Attributes-List-in-VWO) |

For more information about sync modes, refer to the [sync modes](https://docs.hightouch.com/syncs/types-and-modes.md#sync-modes) docs.

## Connect to VWO

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

Enter your **Authorization Token** into Hightouch.

If you don't already have a token, you can generate one [here](https://app.vwo.com/#/developers/tokens).

## Sync configuration

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

### Syncing Attribute Lists

Sync data from any source to VWO Attribute Lists.

Currently, we do not enable the creation of non-existent attribute lists, or the ability to browse attribute lists.
Syncing to VWO Attribute Lists requires a knowledge of the Attribute List ID, which you should be able to find in the VWO console.

#### Column selection

Configuring your VWO sync is as simple as selecting the column in your source which you are associating with the selected Attribute List.

When run, Hightouch will sync this column from your source to your Attribute List, diffing changes and keeping your Attribute List up to date.

## 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).
