# Close

> Close more deals by keeping your prospect data up-to-date and in sync with data in your warehouse

## Overview

Your leads and prospects expect you to have the necessary context before engaging with them. You can accomplish this by syncing lead and prospect data from your data warehouse to Close. You no longer need to worry about executives chasing the wrong leads or engaging with warm ones without proper context.

## Supported syncing

| Sync Type | Description | Supported Sync Modes | API Reference |
| - | - | - | - |
| **Lead** | Sync data from any source to Leads | Upsert, Update | [Lead docs](https://developer.close.com/resources/leads/) |
| **Contact** | Sync data from any source to Contacts | Upsert, Update | [Contact docs](https://developer.close.com/resources/contacts/) |
| **Opportunity** | Sync data from any source to Opportunities | Upsert, Update | [Opportunity docs](https://developer.close.com/resources/opportunities/) |
| **Note Activity** | Sync data from any source to Note activities | Insert, Update | [Note docs](https://developer.close.com/resources/activities/note/) |
| **Custom Activity** | Sync data from any source to custom activities | Upsert, Update | [Custom Activities docs](https://developer.close.com/resources/custom-activities/) |

When inserting Note activities, Hightouch creates and attaches new Note activities to the Lead object you specify in your sync configuration.

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 Close

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

You can generate a Close API Key in your Close account under [**Settings > API Keys**](https://app.close.com/settings/api/).

For more information, refer to [Close's docs](https://help.close.com/docs/api-keys).

## Sync configuration

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

### Record matching

You can match rows from your model to Close records on any unique property.

You must match Contacts by either email or the contact's ID.

### Field mapping

Use field mapping to sync any model columns to Close's default and custom fields.

## 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).
