         The V2 Orders API will not trigger the typical [Order Email](https://support.bigcommerce.com/s/article/Customizing-Emails?language=en_US) when creating orders. To create an order that does trigger this email, you can instead [create a cart](/docs/rest-management/carts/carts-single#create-a-cart) and [convert that cart into an order](/docs/rest-management/checkouts/checkout-orders#create-an-order).
 
+        If you are building an app that creates orders, it must include your app's ID in the `external_source` field of new orders to be approved for the App Marketplace. See [App Store Approval Requirements](/docs/integrations/apps/guide/requirements#functionality) to learn more.

         > #### Note
         > * If historical orders processed on another eCommerce platform are being migrated to BigCommerce, supply the `external_source` field with the code **M-MIG**. This code will exclude the historical orders from the store’s GMV/order count, which factors into pricing.
