Order Cancellation now available on GraphQL Admin API

API

As of GraphQL Admin API version 2024-01, you can use the orderCancel mutation to cancel an order. The mutation allows apps to specify some options for cancellation (eg whether or not to refund the customer, restock inventory quantities, notify the customer) as well as a reason for cancellation and a merchant-facing staff note. The mutation performs cancellation asynchronously in a background job and as such, returns a job that can be queried for using the job API
