If you use Delivery.com or Slice to receive orders, you can add a Start Order call-to-action button on your Facebook Page that will enable people to order food directly through your Page. When people click on the button, you’ll receive those orders through Delivery.com or Slice, and those orders will appear along with your restaurant’s other orders.
Note: Delivery.com and Slice are the only third-party delivery systems we support at this time. If you use Delivery.com or Slice and you don’t have an existing call-to-action button on your Page, the Start Order button will automatically be added to your Page.
Note: If your restaurant has an unmanaged Facebook Page with a Start Order button, you’ll certainly need to claim the Page to make any changes to the Page and edit the Start Order call-to-action button. Learn how to claim unmanaged Pages.
