Out of box, this list is based on customer context and displays the sold products and install base items owned by the customer.

To access this extension point, navigate to **All** &gt; **System Extension Points** &gt; **Scripted Extension Points** and select **CSMServiceDefinitionIntegrations**.

To modify this extension point:

1.  Select the **Create implementation** related link on the extension point record.
2.  Modify the **Script** field and add an API to return product information.
3.  Select **Update**.

    The system adds the implementation to the Implementations related list on the extension point record.

    **Note:** The implementation with the lowest **Order** number is used to return the list of products.
