Facebook can calculate a more accurate return on ad spend or [return on marketing investment](https://en.wikipedia.org/wiki/Return_on_marketing_investment) for Facebook Ads if you upload physical and retail offline events to Facebook.

This connector uploads a feed of customer and offline transactions from Customer Data Platform (CDP) to Facebook. CDP uses a scheduled template report to incrementally push offline event data to [Facebook’s Offline Conversions API](https://developers.facebook.com/docs/marketing-api/offline-conversions/). Refer to the **Parameters** section on the same link for the list of supported fields. Uploads are performed in batches to a single event set in Facebook. Facebook then uses each customer’s Personally Identifiable Information (PII) to match each offline transaction to a user account in Facebook. For large datasets, this process can take 24-48 hours because it takes significant time for Facebook to match the uploaded customer PII to individuals in their identity graph.

Setup
-----

1.  Complete the prerequisites listed by Facebook here: [Offline Conversions API](https://developers.facebook.com/docs/marketing-api/offline-conversions#requirements).
2.  To receive the latest Facebook Partner ID, [contact Acquia Support](https://docs.acquia.com/service-offerings/support#contact-acquia-support "https://docs.acquia.com/service-offerings/support#contact-acquia-support").
3.  Set up the Business Manager Partner Access.
    
    You may already have done this step for [Facebook - Custom Audience](/customer-data-platform/connectors/digital-advertising/facebook-custom-audience). By enabling the Partner Access, CDP is able to connect to your Business Manager (BM) accounts without having to share your username and password.
    
4.  Log in to the Business Manager account.
5.  Ensure that the **Offline event set** is enabled for the current account. You need to share this with Acquia.
6.  Ensure that you either have admin access or at least the access to add the Partners and share the **Offline event set**.
    1.  Go to **Users** > **Partners** and click **Add**.
    2.  Provide CDP’s Partner ID and click **Next**.
    3.  Click **Ad Accounts**.
    4.  In the **Select assets** section, select the required assets.
    5.  Select **Ad account advertiser** as a role.
    6.  Click **Assign Assets**.
7.  Apart from Ad Account asset, select the specific offline event set asset through the **Offline event sets** asset type, and provide enough permission to manage by CDP.
    1.  Go to **Users** > **Partners** and click **Add**.
        
        This adds the Acquia’s account as a partner and enables you to share the resources.
        
    2.  Click **Give a partner access to your assets**.
        
        The system displays the **Add a new partner** section.
        
    3.  Enter CDP’s **Partner business ID** and click **Next**.
    4.  In the **Select asset type** section, click **Offline event set**.
    5.  In the **Select assets** section, select the required assets.
    6.  In the **Offline event set** section, enable **Manage offline event set**.
    7.  Click **Save Changes**.
    8.  Inform CDP and send the Ad Account Id and name to your CDP team.
        
        The account name appears on the **Partners** tab with status as **Pending**. Contact [Acquia Support](/service-offerings/support#contact-acquia-support) and inform them that you have granted the access. CDP adds the account to the system user account. Once it is added, the Pending status disappears.
        
8.  CDP sets up the daily export of the files to Facebook.
9.  In Facebook Business Manager:
    1.  Click **Business Manager** in the upper left section and select **Events Manager → Offline Events**

    2.  In **Events Managers**, go to the second dropdown from right and select **Offline event sets** to view all the available event sets. In a specific event set, you can also get the actual event set id (Offline event set ID). If there is none, you can create a new event set by clicking **Add Data Source → Offline event set** and following the instructions.

    3.  To view the data uploaded through a successful template report, click specific event set id to view the history of all the uploaded events.

    4.  After the template report is executed a few times, review the Facebook account for critical errors and warnings for the CDP event set. Contact [Acquia Support](/service-offerings/support#contact-acquia-support) if there are any changes necessary to the data, template report, and execution schedule.
