`OrderPayment`` Updates Must Be Server-Side
To keep your app secure, requests to cancel an OrderPayment should only be generated on the server-side.
A POST request to /orders/{order_ref}/payments/{payment_ref}/cancel/ cancels an existing OrderPayment.
An OrderPayment can only be cancelled if its status is requires_confirmation or failed. Because only payments in these unsuccessful states can be canceled, this endpoint has no financial side effects.
On success, the API responds with the original OrderPayment object.
