Cancel or refund

put https://example.com/v1/payments/{orderRef}/operations/cancelOrRefund

This operation allows the merchant to cancel (also refered to as "void") or refund a transaction, according to its current state.

You can find below the exhaustive list of cases which may happen.

With a Cancel operation, the customer will not see movement on his bank account, contrary to Refund which gives back the charged amount.

Cancel is only performed when :

the transaction is not yet captured (in which case, the fund reservation on the customer payment method is cleared)
the operation occurs the same day as the capture operation.

If you want to cancel or refund less than the original transaction amount, you can specify the amount in the request body. Alternatively you can specify an amount of 0 if you want to refund the total amount.

Partial operation : 0 <amount < transaction's amount
Full operation : amount == transaction's amount ORamount== 0
