# Configuring a Platform Event Data Source (Managed Package)

For the managed package runtime, configure a Platform Event data source to enable apps to communicate inside and outside of Salesforce.

![Managed Package app icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/resources-global/_corporate/images/managedpackageicon.png) This information is for Omnistudio for Managed Packages. For Omnistudio on standard runtime, see [Omnistudio Help](https://help.salesforce.com/s/articleView?id=xcloud.os_omnistudio_standard.htm&language=en_US).

Platform Events are part of Salesforce’s enterprise messaging platform. A Platform Event combines PushTopic and Streaming Channel. Instead of working with an sObject, Platform Events work with custom objects. See [Platform Event Data Source (Managed Package)](https://help.salesforce.com/s/articleView?id=xcloud.os_platform_event_data_source_1.htm&release=264.0.0&type=5 "For the managed package runtime, configure a Platform Event data source to enable apps to communicate inside and outside of Salesforce.").

To configure a Platform Event data source:

1. In the Cards Designer, in the Layout or Cards pane, from the **Data Source** picklist, select **Streaming API**.
2. From the **Type** picklist, select **Platform Event**.

3. In the **Channel** field, enter the URL of the Platform Event that you created.
4. From the **Operation** picklist, select **Replace** or **Append**.
    
    - Select **Replace** to overwrite the Card with new data.
    - Select **Append** to add new data to the Card.
    
    From the **Get All Messages** picklist, select **True** or **False**.
    
    - Select **True** to get all data from the last 24 hours.
    - Select **False** to get the latest data update.
5. (Optional). Enter values for these properties:
    
    - To drill down to a specific dataset, in the **Result JSON Path** field, enter a path. For example, enter records.results, which drills down to the `results` array and passes the array to the card or card layout.
    - To sort data by a specific data field, enter the field name in the **Order By** input field.
    - To reverse the order of the data returned, select **True** from the **Reverse Order** picklist.

    - Set a **Timeout** value in milliseconds.
        
        The timeout value controls the time that the framework waits for the designated data source to return a response. Timeouts improve handling user interactions with long running processes. Setting an appropriate timeout value allows the application and users to react accordingly to long wait times.
    - Set an **Interval** value in milliseconds.
        
        The card component's data source refreshes continuously at the given interval and checks for changes in data source records. If changes are found, the layout or card component reloads. Setting an interval enables recursive updates of records.
6. To preview a card using real data, add a test variable in the **Test Data Source Settings** fields. See [Testing Data Source Settings (Managed Package)](https://help.salesforce.com/s/articleView?id=xcloud.os_testing_data_source_settings.htm&release=264.0.0&type=5 "For the managed package runtime, add runtime variables to fetch and test your data source.").

    After configuring a Streaming API data source for an LWC card, you cannot preview the card in the Card Designer's Preview pane. To view the LWC card, you must deploy it, and then add the LWC card to a Lightning or Community page. For more information on deploying an LWC card, see [Creating an LWC Card Layout (Managed Package)](https://help.salesforce.com/s/articleView?id=xcloud.os_creating_an_lwc_card_layout.htm&release=264.0.0&type=5 "For the managed package runtime, create an LWC card layout to enable Vlocity Lightning web components."). For more information on adding an LWC card to a page, see [Adding an LWC Card to a Lightning or Community Page (Managed Package)](https://help.salesforce.com/s/articleView?id=xcloud.os_adding_an_lwc_card_to_a_lightning_or_community_page.htm&release=264.0.0&type=5 "For the managed package runtime, beginning with the Vlocity Insurance and Health Summer '19 and Vlocity Communications, Media, and Energy Fall '19 releases, Vlocity supports the Salesforce Lightning Web Component programming model.").
