post https://api.sandbox.clearpay.com/v2/payments/token:/reversal
This endpoint performs a reversal of the checkout that is used to initiate the Clearpay payment process. This will cancel the order asynchronously as soon as it is created without the need of an additional call to the void endpoint. In order for a payment to be eligible, the order must be in an Auth-Approved or Captured state and must be issued within 10 minutes of the order being created.
