New checkoutCharge field added to the Storefront API sellingPlan object
API
Effective April 01, 2022
As of GraphQL Admin API version 2022-04, a new checkoutCharge field has been added to sellingPlan. It consists of a charge type (either percentage or price), and an amount, indicating how much of the product's cost will be charged at the time of checkout. This field is currently restricted behind the extend_selling_plans_api beta flag.
