Cancels the authorisation on a payment that has not yet been captured, and returns a unique reference for this request. You get the outcome of the request asynchronously, in a **CANCELLATION** webhook. If you want to cancel a payment but don't have the `pspReference`, use the `/cancels` endpoint instead. If you want to cancel a payment but are not sure whether it has been captured, use the `/payments/{paymentPspReference}/reversals` endpoint instead. For more information, refer to Cancel.
