| - | - | - | - |
| **Candidates** | Sync data from any source to Great Question candidates | Upsert | [Candidates docs](https://developer.greatquestion.co/reference/overview) |

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 Great Question

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

Enter the following fields into Hightouch:

* **Base URL**: If left empty, the default base URL (`https://api.greatquestion.co/`) will be used.
* **API key** (Required): Refer to the [Great Question docs](https://developer.greatquestion.co/reference/authentication-1) to generate your API key.

## Sync configuration

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

### Syncing candidates

Sync data from any source to Great Question candidates.

#### Record matching

You can match rows from your model to candidates in Great Question on any column in your model and any field in Great Question. Ensure the data types of the model column and Great Question field you select match.
Refer to the [record matching docs](https://docs.hightouch.com/syncs/record-matching.md) for more information.

#### Field mapping

Hightouch lets you sync candidate fields via [field mapping](https://docs.hightouch.com/syncs/mapping-data.md).
You can map data from any of your model columns to default and custom candidate fields.
If you send data for a custom field that doesn't exist, Hightouch adds the field.
Ensure your model's columns have the same data types as the fields you want to sync to.

#### Delete behavior

The [delete behavior](https://docs.hightouch.com/syncs/overview.md#delete-behavior) you select dictates what to do when a row no longer appears in your model's query results. You have the following options:

| Behavior | Description |
| - | - |
| **Do nothing** | Keep the candidate in Great Question with all its synced fields |
| **Delete** | Delete the synced candidates from Great Question |

## 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).
