The source of the checkout. To use this field for sales attribution, you must register the channels that your app is managing. You can register the channels that your app is managing by completing [this Google Form](https://docs.google.com/forms/d/e/1FAIpQLScmVTZRQNjOJ7RD738mL1lGeFjqKVe_FM2tO9xsm21QEo5Ozg/viewform?usp=sf_link). After you’ve submitted your request, you need to wait for your request to be processed by Shopify. You can find a list of your channels in the Partner Dashboard, in your app’s Marketplace extension. You need to specify the handle as the source_name value in your request. The handle is the channel that the order was placed from.
