Void a payment by releasing an already authorized amount, before it is captured, so no funds is transferred from the cardholder to you. This releases the held funds on the customer’s card instead of completing the charge. This cannot be used to "cancel" a pending payment, that has not yet been authorized. *We recommend a minimum timeout of 60 seconds.* :::info Operations are processed synchronously All operations such as `CAPTURE`, `VOID` and `REFUND` are processed synchronously and the outcome is returned directly in the response, meaning webhooks are not required. We **strongly** recommend using the **Idempotency-Key** header, to ensure safe retries in case of network failure. :::
