Hips host will automatically perform reversal if no response is received from card schemes. Therefore you should generally only do reversal for approved authorizations. However, the API also supports blind reversals, meaning you are able to send a reversal even though you haven’t got a response on the authorization. Blind reversals are performed by supplying the original idempotency key instead of the payment id. Authentication Key Type: TerminalApiKeyAuth
