# Create a Marketing App Extension

A marketing app extension represents a third-party app that you use to work with prospects outside of Account Engagement. We recommend setting up a marketing app extension for each third-party app that you use to interact with prospects and store data. For example, if you have a webinar provider, a video platform, and you send out surveys, set up an extension for each vendor.

### Required Editions

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small edition"><colgroup><col></colgroup><tbody><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: <span>Account Engagement <strong>Plus</strong>, <strong>Advanced</strong>, and <strong>Premium</strong> Editions</span></td></tr></tbody></table>

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small permission">
        <colgroup>
          <col style="width:50%">

          </tr>
        </thead>
        <tbody>
          <tr class="">
            <td data-label="User Permissions Needed" class="slds-cell-wrap" style="vertical-align:top;" headers="d41408e68 ">To access Marketing Setup in Salesforce:</td>

            <td class="slds-cell-wrap" style="vertical-align:top;" headers="d41408e68 ">Customize Application</td>

          </tr>
          <tr class="">
            <td data-label="User Permissions Needed" class="slds-cell-wrap" style="vertical-align:top;" headers="d41408e68 ">To access Marketing App Extension for the first time:</td>

            <td class="slds-cell-wrap" style="vertical-align:top;" headers="d41408e68 ">Manage Public List Views</td>

          </tr>
        </tbody>
      </table>

Even if you only have one business unit, the extension must be assigned to a business unit and have associated activity or action types.

1. From Marketing Setup, select **Marketing App Extensions**.
2. Click **New** and enter a name for your extension.
    
    ![Screenshot of modal to create a new extension with the example VidLand, a video platform.](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-pardot-264-0-0-production-enus/5fef4d4f-9a34-45c6-8cd3-e3200b9eeba8/pardot/images/pardot_extensibility_new_extension.png)
3. Enter an API name for your extension, or you can use the name generated when you enter the name of your extension.
4. If needed, enter a description for your extension for internal use.
5. To use the extension’s activities or actions in automations, select **Active in Automations**. You can always return to this step later to activate your extension.
6. Save your work.

You can create as many marketing app extensions as you want. The number of active extensions that you can have at one time depends on your edition. After you create an extension, assign the extension to a business unit.
