# Sync your business hub with your external app

{% hint style="info" %}
**Who can use this feature?**

* Business hub **Owners**
* Only supported using the Cerby web app
  {% endhint %}

As a business hub **Owner**, you can initiate a sync to ensure that the information shown in Cerby is up to date with the information available in your seat-based and paid social apps.

Cerby keeps your business hubs up to date automatically, but you can also run syncs at any time. Whenever you perform manual updates in the external app, Cerby recommends running a sync to ensure the latest information is reflected in your business hub.

To sync your business hub with your external app, you must complete the following steps:

1. Log in to your [Cerby](https://app.cerby.com/) workspace.
2. Select the **Business Hubs** option from the left menu. The **Business Hubs** page is displayed.
3. Click the **More options** (...) icon of the corresponding business hub card. A drop-down menu is displayed.
4. Select the **Settings** option from the menu. The business hub details page is displayed with the **Settings** tab activated.
5. Click the **Sync** button located at the top-right section of the page. A message box is displayed with information about the process. ​**NOTE:** The sync process may take a few minutes depending on the number of users and assets. You can review the progress of the automated task through the **Automation** **Log** page.
6. Activate the **Users** tab. The recently synced app users are displayed in the following tabs of the **User Overview** section:
   * **Onboarded users:** This tab displays the users matched to their Cerby account.
   * **Unmatched users:** This tab displays the users who were not automatically matched.
   * **Guest users:** This tab displays the users matched to a Cerby guest user.
7. Perform one of the following actions described in the [Connect a business hub for your app](/setup-and-admin/business-hubs/connecting-your-apps/connect-a-business-hub-for-your-app.md) article for unmatched users:
   * [Match users](/setup-and-admin/business-hubs/connecting-your-apps/connect-a-business-hub-for-your-app.md#match-users)
   * [Remove unmatched users](/setup-and-admin/business-hubs/connecting-your-apps/connect-a-business-hub-for-your-app.md#remove-unmatched-users)
   * [Exempt unmatched users](/setup-and-admin/business-hubs/connecting-your-apps/connect-a-business-hub-for-your-app.md#exempt-unmatched-users)

Now you are done.
